Regarding that you might have already handled the savedInstanceState, then include 

android:configChanges="orientation"

in the activity in android manifest.

May be it case for activity reload

there is a way you can try:Simply add the "screenSize" attribute like I did below:

<activity
    android:name=".YourActivityName"
    android:configChanges="orientation|screenSize">
</activity>

more details: about it http://developer.android.com/guide/topics/manifest/activity-element.html

You need to override the onSaveInstanceState method. When that method is called, save the data you want to keep to the bundle object. Then in onCreate you should be checking if bundle != null), and if that is true (meaning you saved stuff in the onSaveInstanceState method, update your variables based on values in the bundle.

From the Android documentation, you should avoid using the android:configChanges property:

Note: Using this attribute should be avoided and used only as a last resort. Please read Handling Runtime Changes for more information about how to properly handle a restart due to a configuration change.
