the errors getting r cannot found , keeps suggesting import wrong version of r.

edit: have changed manifest

  

<activity             android:name="info.androidhive.googlemapsv2.mainactivity"             android:label="@string/app_name"             android:theme="@style/appbasetheme"             <intent-filter>                 <action android:name="android.intent.action.main" />                   <category android:name="android.intent.category.launcher" />             </intent-filter>         </activity>  

but still errors

the problem youre importing

import com.google.android.gms.r; 

solution: remove r.java used not google one..
