启动应用程序时，Android 9 手机崩溃

Question

我的应用只在android 9 上崩溃。它在其他android platforms 上运行良好。可能是什么原因？ 我收到以下错误：

ui.activities.StartActivity}：java.lang.SecurityException：调用自 用户 0 作为用户 -1 没有权限 INTERACT_ACROSS_USERS 或 不允许 INTERACT_ACROSS_USERS_FULL

Answer 1

在你的清单中添加这个 android:protectionLevel="signature" 。

添加权限

<permission android:name="android.permission.INTERACT_ACROSS_USERS_FULL" android:protectionLevel="signature"/>

Answer 2

Android 9 具有旋转、省电等新功能。您是否尝试过从代码内部获取设备旋转权限？经常将其设置为纵向模式可能是一个错误。
