I found some post here but I couldnt figure out the solution because I use the navigaton drawer sample by the android studio and I havent figured out everything

Answer 1

If you generated the Navigation Drawer Activity with android studio, in the NavigationDrawerFragment class change the import

android.support.v4.app.ActionBarDrawerToggle

to

android.support.v7.app.ActionBarDrawerToggle
