Android将AppWidgetProvider中的屏幕锁定在活动之外

Question

How to create a simple widget that locks the screen without an Activity , only in an AppWidgetProvider ?

I've tried this solution but the method getSystemService does not exist out of an Activity context.

Thank you very much for every clarifications.

Answer 1

在传递给onReceive()的Context上调用getSystemService() onReceive() 。
