问题 Use case: When geofence triggers we need to contact server ASAP. We have solved this with an implicit BroadcastReceiver calling a Service for several years, but problematic in new versions due to Doze and Oreo background restrictions. Attempted fixes: We moved geofence registering from implicit -> explicit broadcast receiver to get around the "background mode" restriction. We tried to do it as in Googles examples, i.e. the broadcast receiver calling enqueueWork() on a JobIntentService . The

问题 In my app I want to measure how long the media button press was. I registered a broadcastReceiver that listens to the media button press: (please excuse stupid mistakes as I am a beginner...) <receiver android:name="MyRec"> <intent-filter> <action android:name="android.intent.action.MEDIA_BUTTON"> <action android:name="android.intent.action.MEDIA_BUTTON"/> </action> </intent-filter> </receiver> The broadcastReceiver activates a method in an activity (not ideal, but this is just for testing

问题 I am catching the android.intent.action.PHONE_STATE change event by using following code snippet with android BroadCastReceiver. I could recognize the event successfully and handle the incoming calls also can be done by following code. My requirement is identifying calls which are coming form a particular number, end that call through the code and invoke a web service for that incoming event.

问题 I have a BroadcastReceiver that can successfully catch a broadcast, but if I try to call another method from it, it won't always work. Here's my setup: private class MyReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { if (working == true) { //toast to make sure we got here doWork(); } } } The toast within the if gets called, but doWork doesn't execute. Has anyone dealt with a similar issue? 回答1: The Broadcast receiver doesn't have the same
