当我为我的应用小部件使用配置 Activity 时，一旦我使用带有 Android 4.4.2 和 GEL Launcher(默认启动器)的 Nexus 5 将 Activity 设置为 RESULT_OK，它就会崩溃.当我对 Android SDK API 示例小部件进行相同尝试时，也会发生同样的情况.因此我认为这不是我的代码的错.相同的代码使用我的 Nexus 4 及其默认启动器和相同的 Android 版本.错误日志(使用API​​ Examples Widget)如下:

When I use a configuration Activity for my app widget it crashes once I leave the activity with RESULT_OK set using my Nexus 5 with Android 4.4.2 and GEL Launcher (the default launcher). When I try the same with the Android SDK API Examples Widget, the same happens. Therefore I assume it is not the fault of my code. The same code works using my Nexus 4 with its default launcher and same Android version. The error log (using API Examples Widget) is as follows:

查看 com.android.launcher3.Launcher.onActivityResult(Launcher.java:804) 的源代码，似乎变量 mDragLayer 为空.有没有人有解决这个问题的方法?

Looking at the source code of com.android.launcher3.Launcher.onActivityResult(Launcher.java:804) it seems that the variable mDragLayer is null. Does anyone has a workaround for this problem?

推荐答案

我无法将小部件添加到我的主屏幕，并且在googlequicksearchbox"中一直崩溃.经过数小时的搜索和技术支持，我找到了这个.取消选中设置-> 开发者选项-> 不保留活动，修复它.

I could not add widgets to my home screen and kept getting crashes in "googlequicksearchbox". Many hours of searching and tech support, I found this. Unchecking Settings-> Developer options-> Don't keep activities, fixed it.
