Android M Permission Sample using Support Fragment

FragmentNeedingPermission.java

@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
  // ... Some magical things
  
  if (ContextCompat.checkSelfPermission(getActivity(), READ_CONTACTS) == PackageManager.PERMISSION_GRANTED) {
  
    // We have access. Life is good.
    setupContactsPicker();
  } else if (ActivityCompat.shouldShowRequestPermissionRationale(getActivity(), READ_CONTACTS)) {
  
    // We've been denied once before. Explain why we need the permission, then ask again.
    getActivity().showDialog(DIALOG_PERMISSION_REASON);
  } else {
  
    // We've never asked. Just do it.
    requestPermissions(new String[]{READ_CONTACTS}, REQUEST_PERMISSION_CONTACTS);
  }
  
  return magicalView;
}

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
  if (requestCode == REQUEST_PERMISSION_CONTACTS && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
    setupContactsPicker();
  } else {

    // We were not granted permission this time, so don't try to show the contact picker
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
  }
}

What if my app is not targeting M? Would this work?

If you are not supporting M then you don't need to request permissions, pre-M will force permissions acceptance as a condition of installation. You could wrap this in a version check in order to support M and pre-M.

The result wont be returned to support fragment, it will be returned to parent activity with this call.

I think requestPermissions would pass the results to the fragment itself. You can refer this answer on SO.
