Absolutely possible, in AndroidManifest.xml add this to activity:

android:configChanges="orientation|keyboardHidden"

Read this article Handling Runtime Changes. Basically there are two options

Let android handle configuration changes - then your activity will be recreated and onCreate will be invoked again.
Handle it yourself - then your activity won't be destroyed.

Yes it is possible to do this, by adding android:configChanges="orientation" to your manifest.

However, by choosing this path, you lose much of the great resource management in Android.

If you want to appropriately save and restore state since the activity is recreated without the above manifest change, then you will want to look at onSaveInstanceState () and onRestoreInstanceState ()
