Quite often, users complain that when installing an application, their Android smartphone displays the error message “ The application is not installed. A package with the same name already exists" This happens because the new package conflicts with an existing package that has the same name. Every app on Google Play has a unique package name, but that doesn't mean two developers can't develop two different apps and give the file packages the same name. And then the error occurs when you try to install or download the APK file of the same name, and the Android device displays a corresponding message.
In most cases the situation occurs when your phone has the same application has already been installed for multiple user profiles on the same device, and it was not properly removed from each profile. If you try to install a new APK of the same application in such a situation, then you will encounter exactly this error. Therefore, the most obvious solution would be to carefully uninstall the application and then try to install a new APK. So what do you need to do?
Main solution
Go to Settings -> Apps, then find and open app info. After that, open the additional menu (3 vertical dots) and select “Delete” for all users.
This fix works in most cases, but there are some misfires where even after uninstalling the application, all users still have to deal with a package conflict with an existing package with the same name.
Additional solutions
1st option - Allow installation of applications from unknown sourcesTo fix the error “The application is not installed. A package with the same name already exists”, you need to try to allow installation of applications from unknown sources. The corresponding item is available in the phone's security settings.
2nd option - install the application using ADB
- First of all, you need to install Android Debug Bridge for PC and activate the “USB Debugging” mode in the “For Developers” options on your smartphone. (We wrote in detail about how to enable the “For Developers” mode in).
- Next, while simultaneously holding down the power and volume + buttons, you need to reboot the smartphone into “Recovery” mode, and then connect the Android device to the computer using a USB cable.
- Then you need to open the command line and enter the following command there:
adb install -l -r name-of-file.apk
* Instead of name-of-file.apk, indicate the name of the application to be installed.
To use this method, you must have Root rights on your device and install the application. Next, you need to do the following action sequence:
Now you know how to deal with the situation if your Android smartphone displays the error “The application is not installed. A package with that name already exists.” If you want to share your methods or tell me whether the methods suggested above worked, write in the comments. Let's discuss it together.
This article is devoted to the problem when applications are not installed on an Android phone or tablet: the download process does not begin or the download is waiting.
To fully use the gadget on the Android system, you should install it on it different applications, which will comfortably help you watch videos, communicate on social networks, process photos, etc. Often the installation process goes fine, but in some cases it is not possible to install the application or game. Let's look at this problem.
The main reason is the shortage internal memory tablet or smartphone. If the gadget does not have enough memory, it will not be able to save the program installation file and install it. The problem can be resolved in one of the following ways:
Increase
To see exactly where applications are installed, you need to go to the “Memory” menu in the settings. There is a “Installation location” item at the top. Clicking on it will display a list with available options.
To install applications on a memory card, you need to select it in this list. In this situation, the installation file system will download the file and install programs on the microSD. The location of the file does not matter; programs work equally well from the card and from the gadget’s internal memory.
Increase
This operation is not available on all gadgets. It all depends on the shell provided by the product manufacturer.
One more possible reason errors during installation; there may be an unstable Internet connection while downloading the installation file from the Play Market via 3G. It's better to connect to Wi-Fi point to ensure a connection with stable speed.
In addition to problems with programs, errors can occur in Google work account. To eliminate them, you need to delete your account and add it again:
- Open the settings, find the “Accounts” section.
- Select the line “Google”.
- Click on the account you are using.
- Expand the additional menu and select “Delete account”. It is important to pay attention to the nuance that all data associated with the account will be deleted. Therefore, if necessary, we create a backup copy.
Increase
When you delete account, the gadget needs to be rebooted. The next time you turn it on, you should add your account again and try to download programs from the Play Market.
If problems arise with the installation, the last resort would be to flash the device or reset it to factory settings. Flashing is only relevant for devices with a custom system, not the official one.
Correct installation of applications
Every user should know that the application can be installed on Android different ways- APK file and through the Play Market. This allows you to reduce the number of errors when installing software and will allow you to choose a more appropriate method for each specific case.
Instructions for installing the application from the Play Market:
- Launch the Play Market application on Android. If you have not yet added a Google account, the system will prompt you to provide information about your existing profile or create a new account.
- In the search bar, enter the name of the application that you want to install.
- Open the page with the found application. You should make sure that it is compatible with the gadget. Then click “Install”.
- We accept the required permissions.
- We are waiting for the download and installation of the software to complete.
Increase
After successful installation, you will be notified that the application has been installed. It should be opened and checked for functionality. You can perform identical actions on your computer using the Google Play resource:
- In the browser, open the Google Play resource. Log in to your account added to the gadget.
- Find the application, check compatibility and click “Install”.
- If one account is added to several devices, then select the device on which you want to install the application.
Increase
The main condition for remote installation of applications was connecting the gadget to Wi-Fi. The application will not be downloaded from Google Play via mobile traffic.
Application installation mode
If you need to install a program from a third-party source, without using the Play Market, you should prepare the system:
- Open settings, go to the “Security” menu.
- Find the line “Unknown sources” and put a tick next to it.

Unlike iOS and other closed systems, Android developers have provided the ability to install various applications independently, without the participation of Google Play Store and other content stores. Having the .apk file in your hands, you can install it yourself paid application without paying a penny for it.
"Why resort to self-installation by using. apk files? "- you ask, and then that not all applications are presented in the Google Play Store and, moreover, most of them are paid and cost money. All applications for Android have .apk extensions - in fact, this is a kind of archive, the contents of which can be viewed by anyone archivist.
Where to begin?
The first action you need to perform is to allow the installation of applications from unknown sources, go to Settings -> Applications and put a tick next to the item Unknown Sources and click OK.
1. Installing applications using a file manager
After this simple step, you can copy the .apk file to the SD card of your phone. Next, to install the application, you can use any file manager that recognizes and understands apk files. ASTRO File Manager or ES File Explorer are suitable for these purposes.
Run file manager, find the apk file, tap on it and install the application using the standard Android installer.
2. Install applications using the application manager
In addition, to simplify the installation procedure for Android applications, there are special programs- application managers. One of these programs is
InstallAPK will independently identify the apk file and start installing the application on your Android phone. You will only need to agree to install the application and click the "Install" button.
4. Other ways to install Android applications
In case you do not want to install any additional programs, then you can install the application from apk files the old-fashioned way. Launch the standard Android browser and enter address bar browser the following link and the installation will start automatically:
content://com.android.htmlfileprovider/sdcard/FileName.apk
This method is not very convenient and is suitable for those who rarely install programs for Android.
Conclusion
In this article, we tried to describe all the methods known to us for installing an Android application from apk files. If you know other ways to install programs, write to us about them in the comments and we will definitely include these methods in this article. Stay with us.
As is known, users often mobile devices encounter problems when installing a particular application/game. It would seem, what could be simpler? But in practice, standard installation necessary content can often result in hours of agony. It’s worth noting right away that problems, as well as methods for solving them, depend on where the content was taken. Let's look at the main options.
Google Play and Error 406
Sometimes a situation happens that a user wants to download content that is interesting to him from the official Google store, however, instead of the required result, it receives a 406 error. What should I do? Go to the "Settings" section, then "Applications" and select the "All" tab. For the items "Google Services Framework", "Google Play Market" and "Google Play Services" - do the following: remove updates, clear the cache, etc. If everything is done, then go to Settings\Accounts\Google. Here we are interested in the “Setting up account synchronization” item. Uncheck all the boxes and reboot the device. After the reboot, put all the checkboxes back (an error may pop up, but you shouldn’t pay attention to it). Reboot the device again. Ready!
The apk file won't install
There may be several problems here. First, make sure you have Root rights. Without them, installing apk files turns into a real pain. Secondly, if during installation you see a message that the format is not supported, then try using the "ROM Manager" application. Select the "Correct access rights" function and try again. Thirdly, make sure that in the Settings/Application Manager/Application Installation section there is a checkmark next to the “Allow installation of applications from other sources” item. However, from now on you must be completely confident in the sites from which the necessary content will be taken. And finally, fourthly, if nothing helps, then probably the reason may be in the firmware of the device itself. This is especially true for devices with unofficial firmware. In this case, it is recommended to contact a specialist.
If these tips did not help you and the application/game still does not install, then try asking a question in the comments to the appropriate topic.
Installing applications on Android is quite simple; in most cases, you do not need to flash or patch your device in any way! To help novice users and others, we present to your attention a manual on “how to install games and programs on Android,” as well as “how to install games with a cache on Android.”
1. Let's get started, the first thing you should do:
- Go to "Settings" - in the "Personal" section, select "Security" - in the "Device Administration" section, select "Unknown sources" and check the box!
2. Now let’s move on to downloading the necessary files:
- Exist setup files, also called apk and cache files, are additional files for some games and programs! I will describe how to install all this below, first we will figure out how to select the appropriate files for your device.
- Near the links to download files on our website, markers with certain parameters are indicated, here is their list and what they mean:
- @root - applications that will only work on devices with super user rights, which can be obtained by flashing the device or through special programs.
Answer: Go to our info site in the catalog of smartphones and tablets, find your device through a search, if it has firmware, then you will see the corresponding “Firmware” tab, in it you will find instructions for obtaining root rights and instructions for firmware. For example: instructions for Samsung firmware G9208 Galaxy S6
- Adreno, PowerVR, Mali, Tegra 2, Tegra 3 - in addition to the main processor, the devices also have a processor that processes graphics - a video accelerator. You need to select files in accordance with the video accelerator of your device (we mainly use these designations for cache files), but if all the labels are next to the cache link, then there is one cache for everyone!
- For Broadcom processors - try the cache from Adreno
- For Vivante processors - cache from Mali must be suitable
- Having registered on the site, go to “Account” - “Settings”, then find the field with the note “Your PDA device” and begin entering the name of the smartphone/tablet (similar devices will be displayed in the list), after selecting your device, its video accelerator and architecture will be displayed below processor. Or use the CPU-Z program
- If your device is not on the list, use the "My device is not on the list" button and we will add it!
- Having decided which tags correspond to your device, go to the site and download the files!
- If the files were downloaded to the PC, connect the device when USB help cord, wait until the device is detected as a flash drive (for some, you may need to confirm the connection on the device). Next, copy the downloaded file to a folder convenient for you.
- If you downloaded the file directly to the device, then skip the previous step.
- Next, launch the file manager (on Samsung it’s called “My Files”), if it doesn’t exist, install it from the Play Store, for example: “ES Explorer”.
- We find the downloaded file and tap on it, launch the installation, follow the instructions, and when finished, click done!
- If the game does not require additional cache files, then find the game in the list of your applications and launch it!
- Select the previously downloaded cache, unpack it using WinRAR program for PC or ES File Explorer for Android, or their analogues. We place the resulting folder along the path indicated on the game page (above the cache links). In 99% of cases, sdcard = BUILT-IN memory card, NOT removable microSD!
- Next, install the apk as described above.
- /sdcard/Android/data/ and /sdcard/gameloft/games/ - caches located along these paths can be downloaded through the application via wi-fi, EDGE or 3G. Also, it is not necessary to change the cache from version to version.
- /sdcard/Android/obb/ - download caches to this folder only from the site; when updating the version, we download the new cache again.
You will not receive an answer to these questions from the moderator; you will find the answers to them under the list of questions!
- In the description of the cache path, “sdcard” is the built-in memory card, NOT micro SD, which can be removed!
- Will it work on my device?
- Which cache should I download for my device?
- I have no data folders or obb, what should I do? Create it!
- Why can't I see the cache?
- I placed the cache correctly, but it asks me to download XXX MB, why?
- I have little internal memory, and the cache weighs a lot, what should I do?
- How to ask a question correctly to get an answer?
- How to get Root rights?
Answer: Look at the tags and see if your device is supported or not in Google Play. We cannot know whether it will work for you or not, and you can wait a long time for a response from a user with the same device! Better post your results!
Question: Why can’t I see the cache? I posted everything as written.
Answer: The cache is located not on the phone’s built-in memory, but on microSD. Not every game supports placing the cache on an external drive. The exception is some Chinese devices and some Fly models, in these smartphones/tablets when connected microSD cards The external card is being replaced with a built-in one...
Answer 2: Launch the game and see what folder and where it will create, it should be similar to the folder from the cache archive, move the files from the folder in the archive to the folder created by the game.
Answer 3: The folder from the archive must be extracted into the current folder, and not into the folder with the name of the archive (when unpacking via WinRAR)
Question: I placed the cache correctly, but it asks me to download x MB, why?
Answer: If the number of MB is approximately equal to the MB of cache downloaded from the site, then this is not a further download, but a complete download! That is, the cache is not located correctly, read the previous question/answer!
Question: I only have 1GB of internal memory, and the cache is 2GB, what should I do?
Answer: Flash root rights and use a program, for example: Directory Bind.
Answer 2: Look in the phone settings, the option “Install applications on an external SD card”, activate it. It may help if the apk has already been installed; after enabling this option, you need to reinstall it.
Question: How to ask a question correctly to get an answer?
Answer: Write in clear text, without using words only in capital letters, your installation steps: Indicate which card the cache was placed on (external microSD or built-in), write what full cache path you got, whether there is Internet on the device and the model itself device (its characteristics do NOT need to be specified). Have you checked the game's support for your device on the Google Play page?
In this article, I will tell you about the ten most common reasons why programs are not installed. You will learn about the symptoms of a particular cause and will be able to diagnose and eliminate it yourself.
So, let's go - ten reasons why programs are not installed on Windows.
The most common reason why programs are not installed is the lack of a system library NET Framework required version. This library contains resources that are needed for the normal operation of a particular program. Therefore, if it is not there, then the program will not be able to install.
It is recommended that you install all versions of the NET Framework on your computer, starting with 2.0 and ending with the highest version that your Windows supports. This will ensure normal work all programs compatible with your OS.
To find out which NET version Framework is installed on your computer, click on the “Start” button, select “Control Panel”, then open the “Programs” section, and then “Programs and Features” (example for Windows 7).
You can download the versions you are missing on the Microsoft website.
As a rule, if programs are not installed due to the lack of the required NET Framework, a message appears indicating the version that needs to be downloaded.
Lack of Visual C++ and Direct X required version
The next common reason why programs are not installed is the lack of Visual C++ and Direct X components. Visual C++ is necessary for programs written in the popular C++ language, and Direct X is required for most games. As with the NET Framework, there are different versions of these components.
You can find out the version of Visual C++ in the same way as the NET Framework - in the “Programs and Features” section.
And in order to find out the version of Direct X, click “Start” and open “Run” (or ctrl + R). Write down the dxdiag command and click OK.
As a rule, if the program does not install due to the absence of these components or their correct version, a corresponding message appears. The required versions of Visual C++ can be downloaded, and Direct X .
Incorrect Windows bit depth
Windows can be 32-bit or 64-bit. You can install 32 and 64 bit programs on 64-bit operating systems. And at 32 bit systems Only a 32-bit program will work. Therefore, you will not be able to install a 64-bit program on it.
To determine the system bit size, click right click to "Computer" and select "Properties".
The bit depth of the program can be found in its description. If it is not suitable, a corresponding error will appear during the installation process.
Damaged installation file
If, when installing the program, an error appears stating that the installation file is damaged, you should obtain this file again. This can happen due to the fact that the program file was not fully downloaded, or was posted on the site already damaged. To solve the problem, you need to try to download the program installation file from another location.
Missing required DLL
A rare reason why programs are not installed is the absence of some libraries in the system that should be there by default. This happens if you use an unofficial Windows assembly or these libraries were removed intentionally.
The problem manifests itself in a message that complains about some DLL file.
To solve it, you need to download the required DLL file and place it in the desired directory (in system32 or SysWOW64). You can download the libraries.
After this, you should register the library. To do this, click “Start” and select “Run” (or press ctrl + R). Then write cmd and click “OK”. IN command line libraries are registered with the command regsvr32 file.dll, where file.dll is the name of the library file.
Program build curves
A frequent reason why programs are not installed is the crooked hands of pirates who hack them and give them to you for free use, or somehow modify them, that is, make own assembly(repack). To avoid this, read the comments of those who have already tried what you are installing.
It is difficult to say what errors may occur when installing such programs. It could be anything.
Without administrator rights
If you work in an office, then you may encounter that your user does not have administrator rights. Your System Administrator may intentionally prevent the installation of programs. To solve this, ask him for help.
This can happen not only in the office, but also at home if your user on the PC does not have administrator rights.
Blocking by security programs
All computers have antiviruses and some software can be blocked by them. This is also a common reason why programs are not installed. The solution is simple - disable your antivirus or other security program and install the program. If necessary, add this software to the trusted list in your antivirus or security program.
Be carefull. If you are not sure of the reliability of the source of the program, then it is better not to install it if the antivirus complains.
Conflicts with older versions of programs that were not completely removed
If you are updating a version of a program and first uninstalled the old one, and then try to install a new one, a conflict may occur if the components of the old version were not completely removed. This often happens when using the standard Windows uninstaller.
To fix this problem, you must remove all components previous version manually. You can also use cleaning programs, such as CCLeaner.
Equipment disadvantages
Today there are programs and games that can no longer be installed on all computers. So they may have special requirements for video cards, random access memory, processor.
You won’t be able to solve this problem by downloading some files. Here you need to upgrade your computer and buy additional hardware.
To make it easier to install new programs on your computer, you can use the OfflineInstaller website ( 6

To fully use a gadget with Android OS, you need to install various applications on it that will help you comfortably watch videos, process photos, communicate on social networks, etc.
Usually everything goes fine, but sometimes it is impossible to install a game or application. Why is this happening?
Most common cause: random failure
Any equipment is not insured against accidental failure. If the installation failure occurs for the first time, it is most likely an accidental malfunction. Just turn off your phone (tablet) and then turn it on again, i.e. reboot the device.
As a rule, this is enough so that the next time you start the installation everything goes fine.
Low memory
Loading applications on Android devices always occurs only in, and not on, the memory card. After installation, some of them can be copied to the card, but not all. If your device's internal memory is full, or the app you're downloading takes up a lot of memory, you'll need to make room for it to install.
- Check whether your tablet or smartphone has free memory.
- View the list of installed applications, remove those that you no longer use.
- Transfer files for which Android allows this action to the memory card. Usually these are photographs, video and audio files, texts, etc.
- Run a program to clean up memory from garbage - temporary files left behind after running applications. If cleaning has not been carried out for a long time, then a fairly large amount of memory may be freed up after it.
After completing all these operations, try downloading the application you need again. If free space a lot, then it should install without problems.
Unlicensed or incorrect application
Check the source from where you want to install the application. Many gadgets today are used with the installation antivirus programs and other security systems. If the application you are installing turns out to be incompatible with official version Android OS or contains viruses, it will not be installed. The Android OS developer recommends using only applications from the Play Market for installation, since he can guarantee their safe and correct operation.
If you still want to install an application from another source, go to your security settings and allow the installation of third-party software. It is possible that in this case it will be downloaded to the memory of your Android device as a file, and then you will have to launch it using a special installer. But in this case, no one can guarantee that it will work correctly on your device and will not conflict with other applications.
Reset
In the case when all of the above did not help, or if, after various attempts to change the settings, Android almost stopped working altogether, the last resort remains - resetting the settings to the original ones. Before performing a factory reset, remove the memory card and try to save a list of your contacts and other important information on your desktop computer;
Errors when installing applications are a common occurrence among Android users. Therefore, in this article we have collected common problems and solutions.
No installation permissions
When installing applications from unknown sources, before starting the installation or during the installation process, you need permission to install the program.
Solution
- Open system settings.
- Next, select the section – security.
- Check the box next to Allow installation of applications from unknown sources.
In Android 7 and 8, you also need to confirm the application through which the program was downloaded. And in Android 9, individually activate installation from unknown sources for the program that downloaded the application being installed, for example a browser or cloud storage client.
Incorrect application build
If the developer made a mistake when assembling the program or did not activate additional functions, then during the installation process a message will appear indicating that the application cannot be installed.
Solution
Download the program from another source. Ask the author, if possible, to rebuild the package.
The application is not supported by the system version
One of the important requirements during the application installation process is the version operating system. If the developer has implemented support only for Android 6, then the program will be installed on subsequent versions - 7, 8, 9. However, the application will not be installed on earlier versions - 5.1, 5.0, 4.4, etc.
Solution
- If the application does not install from Google Play, try downloading the program from another source. Sometimes developers exaggerate the requirements for installing applications.
- Update your operating system version.
- Ask the developer to include your system version in the list of supported versions. If the program is free, ask for a build that supports your OS version.
The existing program is interfering
Often an installation error occurs when trying to install on an existing application. Moreover, this happens both when downloading applications from Google Play and when installing them from unknown sources.
Solution
- Delete installed application and perform a clean installation.
- Clean residual files of a deleted application.
Issues related to Google Play or Google services
Are you getting an error when installing apps from Google Play? There may be problems with Google services or the app store itself.
Solution
- Open the system settings section, then the application item. Find programs and Google services. Clear cache and data. If that doesn't help, reinstall or update the services.
Low memory
Often applications are not installed due to lack of space on the disk drive. In particular, when 500-1000 MB are free, and the downloaded application takes up, for example, 200 MB.
Solution
- Remove required applications, clear the cache.
- Transfer files from internal memory to external drive.
System failure
Sometimes application installation is prevented by various software and system glitches.
Solution
- Reboot your system.
- Check your phone for viruses.
- If necessary, perform a factory reset and reconfigure the system.
Conclusion
Usually, a problem with installing applications on Android is caused by 1-2 problems. But sometimes the installation fails due to a number of problems. Therefore, to resume normal installation of applications, you need to solve all the existing problems one by one, as shown in the article.
Android App Not Installed is no longer an unknown error code for installing applications as many people experience this on a daily basis. The error message “Android application not installed” usually appears when you try to download and install a program with an .apk extension from a location other than the Google Play Store. The error is confusing at first, but makes sense considering that this unknown error code is not a software problem or a hardware problem when installing programs.
This is a direct result of what you do with your device. Yes, you heard that right. Your erroneous actions may result in the error “Android application is not installed.”
If you want to know more about the causes of this error and how to the best ways to resolve it, read on. Here's everything you need to know...
Here are some reasons for the error “Android application is not installed”
Insufficient storage space
When Android software and data such as photos, videos, music, messages, software, contacts, emails etc. are stored in the internal memory, there is not enough space for other applications, which leads to the “Android App Not Installed” error.
Files are corrupted
If you are not downloading the program from Play Store and choose another platform, the application files usually become corrupted and cannot be easily installed on your device. You need to be sure where you download it. Check the extension name and do not try to install the attached files.

Damaged memory
Corrupted memory, especially a corrupted SD card, is a known cause of the “Android app not installed” error. Even the internal memory can be blocked by unnecessary and unwanted data, some of which may contain an element that interferes with the location. Take this issue seriously because a damaged SD card and even locked internal memory can put your device at risk.
Access rights
Program operations in background and application permissions are not new concepts. Even such errors can cause an unknown error code during installation on a smartphone.
Invalid file
If you already have the app installed, but download a different version that has a unique signed or unsigned certificate, it may also result in the Android app not installed error. This sounds technical, but this and all the other reasons mentioned above can be resolved by you.
An unknown error code while installing an application may occur due to one or more of the reasons mentioned above. Therefore, carefully read the reasons given above to avoid such problems in the future.
