Troubleshooting Opening APK Files
There are many reasons why APK files may not open. Here, we examine and provide some common solutions to these problems below:
Use an app for bundle installation:
Some APK files come in bundles, and you need an installer like Split APKs Installer to have them installed on your device.
By looking at the file extension name, you can distinguish Split APKs from regular APKs. Files with APKM, XAPK, and APKS are not regular APKs and will need a file extension like the Split APKs Installer.
Perform a clean install, don’t update:
You could update to a newer version that works optimally. But that doesn’t always work. How about uninstalling the original app and performing a clean install instead of overwriting by updating it?
Lack of space is not the most common reason for an app not opening, but it’s common. Ensure there is storge space before by doing the following:
- Using an SD card for media like music, videos, and photos.
- Make use of Google Photo’s unlimited storage.
- Use Google Drive or other 3rd party cloud service
- Clear data from apps
- Uninstall used apps
Make sure the file is not corrupted:
Some third-party apps often come corrupted and unsafe. And when they are in this state, they don’t run and are unstable. So, you should always download from known and trusted third-party sites like APK Mirror and similar sites that check apps before making them available.
Enable installation from unknown sources:
You’ll need to allow third-party installations to open unofficial APK files.
