I am developing a simple android app with a TextView and ImageView on the launching page. When I rotate my phone to landscape mode, the app crashes. Though I see that the app is not killed, it just goes away and I can see that it is still running in Android Studio. Following is my code:
Content_main.xml -landscape mode

<TextView

<TextView
