I have started to work on Android M runtime permission. Here I am facing the issue that if requestPermissions
is called from Dialog Fragment
class then onRequestPermissionsResult
not getting called in the same Dialog fragment
class. But if requestPermissions
is called from Activity
class or Fragment
class then onRequestPermissionsResult
method get called in the same class.
Here is my sample code:
public class ContactPickerDialog extends DialogFragment {
private static final int READ_CONTACTS_REQUEST_CODE = 12;
private Context mContext;
private void loadContact() {
if(hasPermission(mContext, Manifest.permission.READ_CONTACTS)){
new ContactSyncTask().execute();
} else {
this.requestPermissions(new String[]{Manifest.permission.READ_CONTACTS}, READ_CONTACTS_REQUEST_CODE);
}
}
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
Logger.d("TAG", "dialog onRequestPermissionsResult");
switch (requestCode) {
case READ_CONTACTS_REQUEST_CODE:
// Check Permissions Granted or not
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
new ContactSyncTask().execute();
} else {
// Permission Denied
Toast.makeText(getActivity(), "Read contact permission is denied", Toast.LENGTH_SHORT).show();
}
break;
default:
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
}
}
private static boolean hasPermission(Context context, String permission){
return ContextCompat.checkSelfPermission(context, permission) == PackageManager.PERMISSION_GRANTED;
}
}
Here in the code I am calling requestPermissions
method of Dialog Fragment
class. So I am expecting to get result in same class.
Any help is appreciated. Thanks in advance!
EDIT: Here I am adding more detail, so that it will be more helpful to others. Previously I have used getChildFragmentManager() to show the DialogFragment.
ContactPickerDialog dialog = new ContactPickerDialog();
dialog.show(getChildFragmentManager(), "Contact Picker");
But As @CommonWare asked me to use activity to show the DialogFragment. I have made following changes and it works.
ContactPickerDialog dialog = new ContactPickerDialog();
dialog.show(getActivity().getSupportFragmentManager(), "Contact Picker");
If you're inside a Fragment
from support library, call requestPermissions()
directly, and your Fragment's onRequestPermissionsResult()
will be called back.
If you call ActivityCompat.requestPermissions()
, then it's the Activity
's onRequestPermissionsResult()
that will be called back.
