Getfragmentmanager() Returns Null, With Android.support.v4.app.dialogfragment Support Libraray

here is the fragment dialog: import android.support.v4.app.DialogFragment; public static class SensorMeasurmentsDialogFragment extends DialogFragment { public static SensorM

Solution 1:

In one of my fragments, I was using replace so when I used add it worked good! might help you

Solution 2:

The activity must extend from FragmentActivity for you to be able to use Fragments. You might have to use a workaround at the moment until Google updates their map library.

You might have to use a modified compatibility lib such as this one:

I ran into this problem also. The problem happens with setRetainInstance(true) only. My workaround is to use the parent activity's FragmentManager object instead of the DialogFragment's FragmentManager.
