i have some problem, my app works fine, but when i load it in Play market, maps does not works correctly. I make next:
keytool -list -v -keystore C:\User\Name/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android
SHA1;com.kostya.app
Where is my mistake? I read this article. Together we can create nice tutorial how to sign app using google maps v2. How to test application at once after loading in play market, without weithing some ours.
When your are creating keystore for creating signed apk you have to do this.
set the password the same like in your created keystore (not android as in debug mode)
keytool -list -v -keystore ~/.android/ YOUR_KEYSTORE -alias YOUR_PROJECT_NAME
