问题 When I call startActivityForResult(new Intent(getActivity(), VkAuth.class), VK_ID); on Samsung (on HTC and Nexus everything works fine), onActivityResult with requestCode == VK_ID and result code 0 (Cancelled) is called before the VkAuth Activity is created. The parent Activity has android:launchMode="singleInstance" . startActivityForResult is called from a Fragment attached to the parent Activity. Log E/AuthenticationFragment: vkLogIn E/AuthenticationFragment: startActivityForResult 9101 E
