Question

我的应用程序服务在LockScreen中启动活动（Manifests.xml中的android：showOnLockScreen =“true”选项）。

LockScreen活动设置onTouch侦听器。

在onTouch中，它会调用完成（）来关闭活动

此完成（）功能会产生警告消息'需要android.permission.INTERACT_ACROSS_USERS'

如何解决？

以下是Manifests.xml

<service android:name=".LockScreenService" />
<activity android:name=".LockScreenActivity"
    android:showOnLockScreen="true"
    android:launchMode="singleInstance"
    android:theme="@style/AppThemeNoAction">
</activity>

以下是onTouch Source上的锁屏活动

@Override
public boolean onTouch(View v, MotionEvent event) {
    finish()
}

以下是警告日志

高于目标API 23版本，应用程序通过弹出窗口获得权限。你有弹出窗口的权限吗？

修改您可以使用checkSelfPermission()和requestPermissions()来检查权限或获得权限。

完成活动后Android android.permission.INTERACT_ACROSS_USERS警告
