I'm using the Firebase App distribution to send out updates to a few testers and the most recent APK I uploaded will not install on Android devices (actually it is several new versions that all have issues installing). I had previously uploaded a version that worked, but all subsequent updates fail with an 'App not installed' error message. I'm confused by the APK files that are generated from Android Studio and I don't recall which version I previously uploaded that worked. In the apk folder there is a debug folder that contains an apk file named app-debug.apk. I'm pretty sure this is the one I used with the successful version of the distribution. There is also a flutter-apk folder with an identically named file app-debug.apk. Does anyone know the difference between these files and which one I should use? That question is a side note as neither of those files work.

I have tried telling my testers to uninstall the previous (working) version and then try to update their Android with the latest version, but the error still occurs. I do not have any issues with my iOS version and that test group.

Do I need to update the debug.keystore file? I have searched many different threads for a solution and nothing seems to work. Any suggestions to debug the issue would be appreciated.

On Android, if the package exported by debug cannot be installed on some devices, such as "parsing failure", you can add a signature file to the debug version. It is better to generate it yourself, and do not use the tool's own. In addition, you can add a signature file to the debug version androidmanifast.xml Statement under application android:testOnly= "False", which may help you
