Android users are constantly on the receiving end of system errors. Every week we see new problems arise that prevent users from accessing their device’s full capabilities.

Recently the most common Android error has been ‘Android App Not Installed‘ or  Android file transfer Mac not working, and unfortunately, it’s more bothersome than other errors.

This error typically appears when users attempt to install an APK that isn’t available on the Google Play Store. Believe it or not, this is a problem that isn’t a direct result of a software or hardware error; it’s how you use the device.

Fortunately, it’s not the end of the world and if you regularly install APKs from a third-party source, use this guide to fix the problem.

Why You Might See ‘Android App Not Installed’

Before eliminating the error, it’s always a good idea to know what causes it. This will prevent it from popping up in the future, and thus, here are some of the reasons.

#1 – Not Enough Storage

If you don’t have enough available storage, then the app won’t be able to install properly. In some cases, the app may attempt to install even if there isn’t sufficient storage, but it will fail, and this error is then shown.

#2 – Corrupt APK File

Downloading the APK file for an app is simple enough, but it can be problematic if you do something to interrupt the download. Make sure that you only download genuine APK files and that you aren’t downloading them from a known harmful source. A file that is corrupt or is a virus will result in this error showing.

#3 – Corrupt Storage Device

Much like hard drives, SD cards can corrupt without any warning. If you try to install an APK on your SD card when the device is corrupt, you’ll likely see this error. Alternatively, it could be the corrupt internal memory (although this usually makes the device unusable).

#4 – Insufficient System Permissions

When you install an Android app, you will receive a request for specific permissions. These permissions are usually vital to an app’s functionality, and if you don’t accept them, you won’t be able to use the app.

#5 – Duplicate Installation

If you are downloading an APK from outside of the Google Play Store, then you won’t get the benefit of duplication detection. If you install a newer version of a third-party APK you already have on your device, it likely won’t run properly.

These are the main reasons that will cause the Android app not to be installed, and if you have an idea of the reason this time, you can avoid future encounters.

Solution #3 – Only Download Apps from the Google Play Store

It should be a rare occurrence to download apps outside of the Google Play Store. Every once in a while, you might want to download an APK that isn’t available in your region, for example. This is fine to do but try not to make it a regular thing as it could result in the Android app not being installed.

Similarly, downloading an app from a third-party source is risky because the APK could have a virus in it which will infect your device. Ultimately, it’s best to stick to the Play Store.

Solution #4 – Don’t Change the Install Location

Android applications, when installed, will give you the opportunity to choose the install location. It’s advisable to leave the install location as the default selection rather than changing it. If you change the location, then errors may occur, and the app may not run properly.

Solution #5 – Allow the Requested Permissions

Every Android app requires specific permissions to function properly. Thus, whenever you install an app, you’ll see a permissions request. If you don’t want to allow these permissions, then you won’t be able to use the app.

If having insufficient permissions is why the Android app is not installed, then you may have accidentally tapped the wrong option. To check what permissions an Android app has, go to “Settings > Apps” and tap on the specific app. From here, you’ll be able to tap on “Reset application permissions” and make sure that everything is correct.

Again, please understand the risks that come with giving an app some system permissions. For example, you should never allow root permissions. This permission gives the app full control of your device, and in most cases, this will be used against you.

Solution #6 – Turn Your Device Off and On

Restarting your device is always worth a shot. This will reload the Android system, and if the error results from a system problem, a restart will fix it.

To restart an Android device, you have to hold the Power key until a menu appears. Tap “Restart”, and your device will have completely rebooted in no time at all.

Solution #7 – Factory Reset

#1 – Open the “Settings” app and swipe down to “Backup & Reset“.

#2 – Tap the “Factory data reset“.

#3 – Next, tap “Reset phone > Erase everything“.

#4 – If you have a password, you must enter it now.
