Poniżej moje manifestu pliku których działania zostały dodane
<activity
android:name="com.hogaming.android.Activities.LoginActivity"
android:configChanges="orientation|screenSize|keyboardHidden">
</activity>
<activity
android:name="com.android.activities.MainActivity"
android:configChanges="orientation|screenSize|keyboardHidden">
</activity>
