Android onActivityResult not called / triggered

Question

I read much about issues with onActivityResult, but it seems that none of the described problems fit to mine, like putting a negative requestCode in start

Answer 1

Had the same problem. check your manifest and make sure you are NOT using single instance:

android:launchMode="singleInstance"

Answer 2

Another variant on this one. From a DialogFragment, you can startActivityForResult. But if your Intent is started from the associated Activity, you must include getActivity() before startActivityForResult. See below (last line):

Activity activeOne=FileDialogWindow.this.getActivity();
Intent intent = new Intent(activeOne,FolderSelectionActivity.class);
String message = "foobar";
intent.putExtra(EXTRA_MESSAGE, message);
getActivity().startActivityForResult(intent,1);
