Answer 1

you should use

getActivity.getSupportFragmentManager() like
//in my fragment 
SupportMapFragment fm = (SupportMapFragment)    
getActivity().getSupportFragmentManager().findFragmentById(R.id.map);

I have also this issues but resolved after adding getActivity() before getSupportFragmentManager.

Answer 2

getSupportFragmentManager() is not part of Fragment, so you cannot get it here that way. You can get it from parent Activity (so in onAttach() the earliest) using normal

activity.getSupportFragmentManager();

or you can try getChildFragmentManager(), which is in scope of Fragment, but requires API17+

Answer 3

For me I made sure to import v4 like this:

import android.support.v4.app.DialogFragment;

Then used:

getActivity().getFragmentManager()

Answer 4

If you're instantiating an android.support.v4.app.Fragment class, the you have to call getActivity().getSupportFragmentManager() to get rid of the cannot-resolve problem. However the official Android docs on Fragment by Google tends to over look this simple problem and they still document it without the getActivity() prefix.

Answer 5

For my case, I made sure that Fragment class is imported from

android.support.v4.app.Fragment

Not from

android.app.Fragment

Then I have used

getActivity().getSupportFragmentManager();

And now its working. If I use activity instance which I got in onAttach() is not working also.

Answer 6

Inside a Fragment subclass you have to use getFragmentManager in place of getSupportFragmentManager. You will get the support one if the import are from the support library.
