On change screen orientation, new activity created

android, android-activity, java, screen-orientation, youtube

Solution

In your AndroidManifest.xml add, android:configChanges and this would avoid the activity being re-created on orientation change. I hope your landscape and portrait mode has the same layout.

    <activity android:label="Your Activity Name" 
    android:configChanges="keyboardHidden|orientation|screenSize"
      android:name="com.yourpackage">

To add more to this, i would suggest you to look at the `onPause()` and `onResume()` methods and if you are playing with Fragments then have a watch on `onSaveInstanceState` and `onRetainInstanceState` rather than applying the xml changes as "Activity is destroyed by design."

Problem

I'm relatively new to Android but have made quite a few apps over the past year so forgive me. I know that when you are running an app on a device and change the screen orientation by turning the device the activity that is showing is completely recreated. I go to the youtube app (I am using Nexus 7 w/ Android 4.2.2) and play some video and then flip the screen to change orientation. The video keeps playing and everything is re-sized accordingly... How is this possible if the activity is completely recreated? Thank you.
