Google Maps Api Key Not Working V2

I had an android application that utilizes google maps. I have followed the instuctions and made the app working in debug mode using the debug key. I have retrieved my SHA-1 key fr

Solution 1:

You're generating an ApiKey for the Google Maps V2, but you are using the v1 MapView com.google.android.maps.MapView. On the Android Maps V2 API, the key is placed on the manifest, and you use com.google.android.gms.maps.MapView to show the map, using the Google Play Services Library.

I suggest reading the overview section here to learn how to setup your Project with the Google Play Services Library, and looking at the new API Reference here.

Solution 2:

If you are developing google maps api. You need to have two sets of map api key. One map api key that is generated by using your SHA1 fingerprint from your debugging keystore, this map api key is to be used when you are debugging your app in eclipse and running it from there. The other map api key is generated by using your SHA1 fingerprint from official or production keystore, this map api key is used when you will signed or publish your app.

I think you are experiencing mismatch of your keys there since the map api key on the manifest is from debugging keystore and you have signed your app with your official keystore.

Also I think you are developing MapView. It is recommended now to use MapFragments now. I have links here that might help you.
