Android users are constantly on the receiving end of system errors. Every week we see new problems arise which 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 if you do something to interrupt the download, it can be problematic. 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 appear. Alternatively, it could be the internal memory that is corrupt (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. This means that 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 installed, and if you have an idea of what the reason is this time, you can avoid future encounters.

Solution #2 – Clearing Your Storage to Fix ‘Android App Not Installed’
Keeping your storage clear of unnecessary or junk files is always a good idea. Not only will it minimise the number of errors that you experience but it will also make more space for data that is actually important. Go to “Settings > Application Manager” and see which apps are filling the most storage on your device.
Focus on the apps which are the heaviest and either select “Uninstall” or, if the app data is the problem, tap “Clear data”. You might find that your games are the problem, so if you stop enjoying an Android game be sure to delete it.
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 Android app not 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 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
It goes without saying that restarting your device is always worth a shot. This will reload the Android system, and if the error was a result of a system problem, a restart would fix it.
To restart an Android device all you have to do is hold the Power key until a menu appears. Tap “Restart”, and in no time at all, your device will have completely rebooted.
It’s worth mentioning that you should restart your phone or tablet every so often. Doing this won’t just reload the Android OS, but it can also lessen the stress put on the device’s hardware.
Solution #7 – Factory Reset to Fix ‘Android App Not Installed’
Finally, a factory reset might be in order. If you don’t yield successful results from any of the other fixes, then factory resetting Is worth considering. Follow the simple steps below to factory reset your Android device.
Step #1 – Open the “Settings” app and swipe down to “Backup & Reset”.
Step #2 – Tap the “Factory data reset”.
Step #3 – Next, tap “Reset phone > Erase everything”.
Step #4 – If you have a password you must enter it now.
Step #5 – The factory reset will take about 5 minutes, and once it’s complete, you can attempt to install your app.
This will wipe all of your personal data, so please take a backup using Google Drive. Alternatively, use dr.fone – Android Transfer as we previously mentioned for the best results.
