broadcastreceiver

问题 I've read several questions concerning similair issues, but they do not provide me with the solution. In my Android app I fire off a notification (in the Application class to be specific, which is actually started from a C2DM push event). I then want to receive an Intent when the "clear all" button is pressed on the notifications: notification.deleteIntent = PendingIntent.getService(this, 0, new Intent(this, NotificationDeleteReceiver.class), 0); In my NotificationDeleteReceiver.class I got

问题 Is there any reliable way to get a Context from a Service ? I want to register a broadcast receiver for ACTION_PHONE_STATE_CHANGED but I don't need my app to always get this information, so I don't put it in the Manifest . However, I can't have the broadcast receiver be killed by the GC when I need this information so I'm registering the broadcast receiver in a Service . Hence, I need a Context to to call registerReceiver() . When I no longer need the ACTION_PHONE_STATE_CHANGED I unregister

问题 When I pass extras to a PendingIntent, the message is never received by the sendBroadcastReceiver, because the onReceive() method of this BroadcastReceiver is never called. Why is this happening? public class MainActivity extends Activity { private static String SENT = "SMS_SENT"; private static String DELIVERED = "SMS_DELIVERED"; private static int MAX_SMS_MESSAGE_LENGTH = 160; private static Context mContext; private BroadcastReceiver sendBroadcastReceiver, deliveryBroadcastReceiver;

问题 I have a simple BroadcastReceiver set up to do something when the user gets an incoming SMS. But I need it to run in the background and when the device is asleep. So would I use a Service that starts the BroadcastReceiver ? If so, can someone give me some pseudo-code? And how would this work if the device is asleep? 回答1: I have a simple BroadcastReceiver set up to do something when the user gets an incoming SMS. OK.

问题 I was wondering if it is possible to find a list that includes all the receivers associated to a certain action. For example I have the following receiver that executes everytime that an SMS is received: <receiver android:name=".SmsReceiver" android:enabled="true"> <intent-filter android:priority="101"> <action android:name="android.provider.Telephony.SMS_RECEIVED" /> </intent-filter> </receiver> So with the priority="101" it´s executed even before than the default message service in Android.
