I made a simple app in android studio

Question

i generate the apk file install it in my phone and it works perfect.
but i send the apk file thru whatsapp to another device but when i try installing it in the other device it says there was a problem parsing the packages.
anyone can help me whats wrong with my app

Answer 1

Either the file was corrupted during the process of sending or your other device doesn't support it, e.g the android version is too low. Check what api level you used and see which android version that corresponds to, and then check if your device has that version or higher.

Answer 2

your app is fine but you can't just build apk file from your installed application because installation files will be missing. you'll have to build it in android studio itself and send that apk file on whatsapp
