i get the error on case 114 KaabaLocatorFragment() when i highlight this line it says

required android.support.v4.app.Fragment found it.bellotti.navigationdrawer.compass.KaabaLocatorFragment

also the case 114 is new line i just added to this project , i wanted to just ad a compass layout and class to this project so here is the line am having problem here is kaabalocatorFragment

Answer 1

You are using the support library v4 on your MainActivity, but the fragment KaabaLocatorFragment is using the native fragment.

The fragment KaabaLocatorFragment need to extends the support.v4 library

Inside the KaabaLocatorFragment, try change this:

import android.app.Fragment;

to this

import android.support.v4.app.Fragment;
