Solution to ‘Application not installed’ error on Android

How to fix ‘App not installed’ error on Android

If the app comes from outside the Google Play Store, first of all let’s make sure that we can download APKs outside the Play Store by accessing Settings> Security> Install unknown apps and choosing here from where to install the APKs. Confirmed this point, again in Settings> Security we can limit the behavior of Play Protect, which is the antivirus system of the Google Play Store and may be blocking the installation of applications.

And another possible solution is through the file system, for which we will need a file explorer like ES File Explorer –download below-. We open it, go to the root of the system and look for the folder System for delete all residual data that could exist from the app to reinstall. Now we will return to the root of the system, we will go to the folder Data and from it, again, we will delete all the data of the application to be reinstalled.

Why am I getting the ‘Application not installed’ error?

Google is somewhat imprecise when displaying a error in android; so it is not possible to always know, with one hundred percent certainty, for what is this. But this problem can be caused by a bad uninstall that has left residual files, for example, or other problems like an automatic blocking of Google Play Protect. Obviously, the first case will occur when that app has already been installed on the device and, for whatever reason, we reinstall it, receiving this error. However, there may be a few more causes:

Wrong file

If you installed an application and then tried to install a variant of it but with a different certificate (with or without signature), then a technical error will occur showing the message β€œApplication not installed”.

Damaged storage

A corrupted SD card can also cause the “Application not installed” error in Android. In fact, the internal storage can also cause failure if it contains unnecessary data or that alters the storage location. To stop this inconvenience, there are ways in which you can repair a damaged micro SD card, it is best to try this before disposing of the memory.

App permission

It is possible that the permissions of the application cause the error in your system. For this reason, it is convenient that you go to the “Settings”, then to the “Apps” menu and select “Reset application permissions”, in order to allow the installation of Apps from other sources.
