问题 We are about to update our App Android API 26. In the documentation about Broadcast receiver it says that Apps that target Android 8.0 or higher can no longer register broadcast receivers for implicit broadcasts in their manifest Implicit broadcast receivers are described as a broadcast that does not target that app specifically.

I created a BroadcastReceiver and it runs only when my app shown in recent apps menu. If I remove my app from the recent apps the BroadcastReceiver will stop working.

You receiver
