try insert into AndroidManifest.xml this code:
android:configChanges="keyboard|keyboardHidden|orientation"

      <activity
            android:label="@string/app_name"
            android:name=".MyActivity" 
            android:screenOrientation="portrait"
            android:configChanges="keyboard|keyboardHidden|orientation"
