android - Google Map Api v2 shows "V/GoogleSignatureVerifier : signature not valid" error message in log

Question

I am developing an Android application using google map api v2 to show a Map in a Fragment. When I run the application, I always got this error message poppin in my log every now and then.

Things I've tried:

• Erasing the debug.keystore and rebuilding the app.
• Downgrading the Google Play Service and upgrading it again.
• Deselect Offline Work

Nothing does the trick so far...

Once upon the time in the Log tab :

Answer 1

When You make signed apk then you have to put SHA-1 Of that keystore in Google Api console where u enabled GoogleAPI V_2 enabled.Then Generate API key again and put that API key into your manifest file.
