startActivityForResult(...)立即返回0 [英] startActivityForResult(...) immediately returns 0

问题描述

当我在Samsung上调用startActivityForResult(new Intent(getActivity(), VkAuth.class), VK_ID);时(在HTC和Nexus上一切正常)，在创建VkAuth活动之前，将调用具有requestCode == VK_ID和结果代码0(已取消)的onActivityResult.
父活动具有android:launchMode="singleInstance". startActivityForResult是从附加到父Activity的Fragment调用的. 日志

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/AuthenticationFragment: onPause
E/MainActivity: onPause
E/MainActivity: onActivityResult before super: request - 271245, result - 0
E/AuthenticationFragment: request - 9101, result - 0
E/MainActivity: onActivityResult after super: request - 271245, result - 0
E/AuthenticationFragment: onPause
E/MainActivity: onPause
E/VkAuth: onCreate
E/VkAuth: onResume

推荐答案

在我删除了android:launchMode ="singleInstance"之后，此错误行为停止了

after i removed android:launchMode="singleInstance", this misbehaivior stoped
