i have an app with various fragments and the problem is when the phone rotates, the app displays other fragments from the begining. it does not close the current fragments but looks like layers on top of each other. any help i'd be grateful. thanks

If you are adding multiple fragments to your activity then when you rotate your phone , activity gets re created and all your fragments get displayed again . You have to store the current fragment at the time of rotation and display it back when rotated – Vivek Mishra Dec 29 '15 at 05:22

Try this to add in your AndroidManifest
<Activity
....
....
android:configChanges="orientation|screenSize">

You need to check for a savedInstanceState, and if it exists, don't re-create your fragments. just check if is null or not
as shown below
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
if (savedInstanceState == null) {
// Do your oncreate because there is no bundle
}else{
// Do that needs to be done even if there is a saved instance, or do nothing
}
}
check this for more detail.

no, you need to maintain state of old fragment with super.onCreate(savedInstanceState);. So maybe set tag and find the fragment if it exist, or pass null bundle to super. find out more http://developer.android.com/guide/components/fragments.html – Amit Vaghela Dec 29 '15 at 05:40
