System broadcast not delivered to the broadcast receiver












0














I'm trying to implement a receiver that reacts to Bluetooth devices being connected or disconnected. However, I only receive the broacasts when the application is open.



I've added the receiver to the manifest:



<receiver android:name=".BleReceiver"
android:enabled="true"
android:exported="true">
<intent-filter>
<action android:name="android.bluetooth.device.action.ACL_CONNECTED" />
<action android:name="android.bluetooth.device.action.ACL_DISCONNECTED" />
</intent-filter>
</receiver>


And my receiver looks like this:



public class BleReceiver extends BroadcastReceiver {
private static final String TAG = "BleReceiver";
@Override
public void onReceive(Context context, Intent intent) {
Log.d(TAG, "Got intent: " + intent.getAction());
}
}


This works just fine when the app is open, but if I eg. use the task switcher and swipe the activity, no broadcasts are received anymore.



The output of adb shell cmd package query-receivers --brief -a android.bluetooth.device.action.ACL_CONNECTED looks just fine:



Receiver #3:
priority=0 preferredOrder=0 match=0x108000 specificIndex=-1 isDefault=false
com.example.blelistenerapp/.service.ble.BleReceiver


Also, I checked the implicit broadcast exceptions, and these two actions are listed there.
