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);
  }
}

On Pre-M, this will just work because ContextCompat.checkSelfPermission() will return true. On M, the support library components handle everything else correctly.

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.
