Android Question App app not installed....

[Beja]

Hello all,
This error message pops up each time I try to install a new apk file.. I changed the package name twice without positive result.
The msg says: "app not installed as package appears to be invalid"
Any help appreciated ..

Check if you have enogh space on your phone

It's possible there are multiple apps with the same package name in your phone.

This is not possible as Android uses the package name to uniquely identify an app so if you load another app with the same package name it tries to replace the existing app.

"app not installed as package appears to be invalid" is not a very helpful message unfortunately. Are you using an old version of B4A and trying to target SDK 31 or higher?

Also try to reduce your target SDK to 30 or lower and see if the error goes away.

Yup!
Andrew! I really appreciate your help! the Android version was the culprit.. I came down one by one and when reverted to v27 it worked like a charm.
The app is old. All thumps up..

Are you using the latest B4A IDE? If not then I think I know what the problem is.
