android:configchanges="keyboardhidden|orientation|screensize"

add activity element in manifest

like

<activity              android:configchanges="orientation|keyboardhidden|screensize"             android:screenorientation="unspecified"             android:name=".launchingpageactivity"             android:label="@string/app_name">             <intent-filter>                 <action android:name="android.intent.action.main" />                 <category android:name="android.intent.category.launcher" />             </intent-filter>         </activity>`
