How to manually call broadcast re

Answer 1

1. The way to launch a BroadcastReceiver manually is by calling

Intent intent = new Intent("com.myapp.mycustomaction");
sendBroadcast(intent);

where "com.myapp.mycustomaction" is the action specified for your BroadcastReceiver in the manifest. This can be called from an Activity or a Service.

2. It is known that Android allows applications to use components of other applications. In this way, Activitys, Services, BroadcastReceivers and ContentProviders of my application can be started by external applications, provided that the attribute android:exported = true is set in the manifest. If it is set to android:exported = false, then this component cannot be started by an external application. See here.
