The Android operating system has its own application store Play Market. Therefore, users are recommended not to scour third-party resources in search of software, but to download it from an official, verified and moderated source. This is all very well, but sometimes the installation is interrupted by an error. The message “Application not installed” appears on Android - what to do in this case? There is nothing critical about this error, let's try to get rid of it together.
If during the installation of the software the error “Application not installed” occurs, then it’s time to clean the operating system of debris.
There really is a lot of it here - it is formed as a result of the operation of the OS and applications, and in quite large quantities. The presence of garbage leads to errors and failures, so you need to get rid of it. To do this, we will use the popular Clean Master application - it must be installed in advance, among the first applications.
- How is cleaning done?
- Launch the application;
- We start garbage analysis;
We remove the found garbage.
Finally, you can unload unused applications - this is done with the click of a button. If you want to achieve more expressive results, your smartphone or tablet should be restarted. After you have cleared the operating system of debris, try installing the software again - go to the Play Market and run the re-installation. If everything went well and critical junk was removed, the installation of applications will proceed without errors. Activate cleaning every time you notice any errors in operation operating system
Android. Instead of the Clean Master application, you can use any other applications to clean and speed up Android devices, including those combined with antivirus utilities
. Many handsets also include basic memory cleaning tools. More and more often, smartphones have built-in cleaners. An example of this are devices from Huawei and Xiaomi - they use standard tools
- to clear RAM and user memory. There are many advantages from them:
- There is no need to use third-party software, sorting through dozens of options;
- They know exactly what should be deleted and what should be left in memory.
In addition, there is no need to download them - everything is already on board.
Remove unnecessary applications and files
I got an "Application not installed" error on Android - what to do? Most likely, it’s time to deal with unused software. It's cluttering internal memory and prevents normal installation. As practice shows, errors occur even when free memory less than 500-700 MB remains. At the same time, many applications installed on the system are practically not used. Why keep them then? Feel free to demolish unnecessary applications and free up space.
You should also figure out where you store your music, photos, and videos. If all this is stored in the built-in memory, you need to revise and transfer the files to a memory card or copy to HDD your computer. After removing the software and files, launch Clean Master, clean up the garbage and proceed to reinstall the applications.
It is better to store photos and videos in the cloud. For example, in " Google Drive"or "Cloud Mail.ru". Initially, 8-10 GB are available to users, but this volume can easily be expanded using paid plans. As an example, consider tariff plans cloud storage from Mail.ru:
- 64 GB – 799 RUR/year or 99 RUR/month;
- 128 GB – 1550 rub/year or 169 rub/month;
- 256 GB – 2350 rubles/year or 249 rubles/month.
Promotional codes and promotions from cloud storage providers will help you reduce the cost or get free additional disk space. As for music, use numerous music services to listen to it - these are “Yandex.Music”, “VKontakte Music”, “Google Music”, “ Apple Music" and many others. Moreover, mobile operators provide them with free traffic.
Moving software to a memory card
If your Android device shows the error “Application not installed” and starts complaining about lack of memory, you need to delete some applications. Didn't find anything you didn't need? Then move some of the applications to the memory card - this is done using standard methods and with the help of an additional software. The performance of applications may decrease slightly, but there will be space for installing the necessary software.
Please note that some phones do not support installing and moving programs to memory cards or do not have card slots at all.
Getting rid of errors by rebooting
About itself in a simple way We still forgot to get rid of errors - this is the most banal reboot. It will help get rid of simple errors in the functioning of the operating system and bring it back to normal. Every user can reboot Android devices - to do this, you need to hold the on/off button until the corresponding menu appears. Next, select the “Restart” item, wait for the reboot and proceed to reinstall the applications.
Virus cleaning
Viral infections can impair the functionality of the operating room Android systems. As a result, various errors may appear in it, interfering with the normal installation of applications. Therefore, it is very important to have at least the simplest antivirus on board - install it in advance, immediately after you purchased your smartphone. After thoroughly checking for virus infections, you should begin reinstalling the necessary applications.
If your device is damaged and clogged to the point that cleaning and checking no longer help, try resetting to factory settings ( Hard Reset). Don't forget to first copy important data to a secure medium or cloud storage.
Alternative applications
In some cases, applications are incompatible with a specific smartphone or operating system version. You'll have to look for alternative software with similar functionality. Another thing is that it is impossible to find a replacement for the same Sberbank Online. But for social network There are many alternative clients on VKontakte. Additionally, if you receive an "Application not installed" error, you can contact the developer of that application at Google Play- it will help solve this problem.

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 applications and give the packages of files the same name. And then an error occurs when trying to install or download the same name APK file, and the Android device displays a corresponding message.
