here is the source code for isAdded :
/**
* Return true if the fragment is currently added to its activity.
*/
final public boolean isAdded() {
return mActivity != null && mAdded;
}
indeed ... mActivity is null...
I guess I have to recreate this fragment from scratch since I've lost
its activity owner ?
what cause this reference on mActivity being lost ?
if its the onPause => onResume, what's the point of having a onPause
onResume methods to implement in Fragment, if we have to recreate it
anyway ?
