Requirement: "adb install" is not possible due to USB write restrictions on my machine. So, I can only install the .apk file via phone memory.
Issue: “App is not installed” error occurs when trying to sideload APK from external sources (ask file from internal/external phone memory).
Device Info: Samsung M30S [Android 11]
Please Note: I checked below
- The phone has sufficient Storage
- Installation from unknown sources in device settings is allowed
- Did clean installed not the update
- Tried to install on different devices (2 devices)
Tried almost all available options which I found over the internet. Some are as below, but none worked:
- Disabling Google Play Protect
- Resetting App Preferences
- Tried APKs created with different ABIs
One possible reason could be the corrupted app, but I am not sure about it as this is getting installed on the emulator and a few days back same was getting installed on phone as well. Even the older .apk files are getting installed properly but not the new ones.
Any help/leads in this are highly appreciated.
