java.lang.IllegalStateException: Could not execute method of the activity

Problem
Caused by: java.lang.IllegalStateException: A required meta-data tag in your app's AndroidManifest.xml does not exist.

In my case i am missing "com.google.android.gms.version" in manifest file.  You must have the following declaration within the <application> element:     <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />
Solution
paste the
             <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />
