android - 主屏幕应用程序小部件配置 Activity 在 GEL 启动器下崩溃

Question

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 的 Nexus 5 和 GEL Launcher(默认启动器)设置 RESULT_OK 离开 Activity，它就会崩溃。当我对 Android SDK API Examples Widget 进行相同的尝试时，同样的事情发生了。因此我认为这不是我的代码的错。相同的代码在我的 Nexus 4 及其默认启动器和相同的 Android 版本上工作。错误日志(使用API​​ Examples Widget)如下:

查看 com.android.launcher3.Launcher.onActivityResult(Launcher.java:804) 的源代码，变量 mDragLayer 似乎为空。有人有解决此问题的方法吗？

Answer 1

我无法将小部件添加到我的主屏幕，并且在“googlequicksearchbox”中不断崩溃。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 -> 开发人员选项 -> 不要保留 Activity ，已修复。
