Google maps in my app is not visible

Question

When I launch my app I get the following error:

V/GoogleSignatureVerifier(4962): com.myapp.application signature not valid.

I have read that debug.keystore default key has only 1 year validity, so one must delete it afterwards to let android studio generate a new one. Eventually I did it but the error remains still.

Google maps in my app is not visible anymore after this move...

Please help if you can.

Answer 1

This warning is caused by a bug introduced in Google Play Services 9.x. It can be safely ignored, it will not cause any issues with your app and should go away with a future update to play services.

This issue has been acknowledged by an engineer at Google in the answer to this post.

Answer 2

When you delete debug.keystore then SHA1 fingerprint also changes. So you will need to get the latest SHA1 and then update it to the google map api developer console to get the Map.
