Remove all fragments from container

by

Its very simple just loop through all the fragments and remove it

for (Fragment fragment : getSupportFragmentManager().getFragments()) {
    getSupportFragmentManager().beginTransaction().remove(fragment).commit();
}

But in case of Navigation Drawer be sure to check it, if you try to remove it you will get error.

for (Fragment fragment : getSupportFragmentManager().getFragments()) {
  if (fragment instanceof NavigationDrawerFragment) {
      continue;
  }
  else { 
      getSupportFragmentManager().beginTransaction().remove(fragment).commit();
  }
}

Last but very important be sure to check for null before doing any fragment transactions

for (Fragment fragment : getSupportFragmentManager().getFragments()) {
    if (fragment instanceof NavigationDrawerFragment) {
        continue;
    }
    else if (fragment != null) {
        getSupportFragmentManager().beginTransaction().remove(fragment).commit();
    }
}
