  • (SOLVED)Android: "App not installed."? Can't install Android APK File On Android Device?

Hi,

I can export an Android APK file just fine from current Godot 3.x on Windows 10.

When I try to install the exported Android APK file on my device(Samsung Galaxy S7 Edge Smartphone) I receive error: "App not installed."?

I don't know how to troubleshoot the above, please help, thanks!

If you encounter the "App not installed" error message when trying to install an APK file on an Android device, several reasons could be causing this issue. Here are some common solutions:

Unknown Sources: Ensure that your device is set to allow installations from unknown sources. To check this, go to your device's "Settings," then "Security" or "Biometrics and Security," and enable the "Unknown Sources" option.

Corrupted APK File: The APK file you downloaded might be corrupted. Try downloading the APK again from a reliable source.

Insufficient Storage: Check if your device has enough storage space to install the app. If your device is running low on storage, free up some space and try installing the app again.

Incompatible Architecture: Make sure that the APK file corresponds to the architecture of your device's processor (e.g., ARM, ARM64, x86). Installing an APK with an incompatible architecture can result in the "App not installed" error.

App Conflict: If you are trying to install an app with the same package name as an existing app (including system apps), you may encounter conflicts. Uninstall the existing app or choose a different package name for the new app.

App Version Conflict: If you're trying to install an older version of an app over a newer version, it may cause issues. Uninstall the newer version first and then try installing the older version.

App Signature Mismatch: If the APK has been modified or is not from a trusted source, the app signatures might not match, leading to installation issues. Ensure that you are downloading APKs from reputable sources.

Device Compatibility: Confirm that the app is compatible with your device's Android version. Some apps may not work on older or newer versions of Android.

Install via Package Installer: Instead of directly opening the APK file, try using a file manager to locate the APK, and then choose "Package Installer" when prompted.
