JellyBean中的通知-添加操作不起作用

Question

Need some help with building an Jelly Bean notification with custom button (using addAction). The problem is, that i cannot just make it working. Basically, i want to build notification with following parameters: on notification click it must bring one of my activities up, on button click - play-pause player, which is running, when notification is shown. My code is: Receiver:

private BroadcastReceiver onNotification = new BroadcastReceiver() {

    @Override
    public void onReceive(Context context, Intent intent) {
        Log.d("NOTIFICATION", "Received broadcast");
        Bundle extras = intent.getExtras();
        int state = extras.getInt("state");
        if (state == 1) {
            playPauseMethod();
        }

    }

};

In onCreate method of activity i've added:

IntentFilter notif_iff = new IntentFilter(
                    MainService.NOTIF_BROADCAST);
LocalBroadcastManager.getInstance(getActivity()).registerReceiver(
                    onNotification, notif_iff);

Code in MainService is following:

public static final String ACTION = "com.formatbce.mdrive.action.UPDATE_UI";
public static final String NOTIF_BROADCAST = "com.formatbce.mdrive.action.NOTIF_BRD";
Intent in = new Intent(ACTION);
Intent notifInt = new Intent(NOTIF_BROADCAST);
private NotificationManager mNM = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

private void showNotification(final int statusBarIconID,
        final int bigIconID, final int ppIconID, final String contentTitle,
        final String contentText, final boolean showIconOnly) {
    PendingIntent layoutIntent = PendingIntent.getActivity(this, 0,
            new Intent(this, MediaFragmentActivity.class), 0);

        int state = 1;
        notifInt.setAction("blabla");
        notifInt.putExtra("state", state);
        PendingIntent mIntent = PendingIntent.getBroadcast(
                getApplicationContext(), 0, notifInt,
                PendingIntent.FLAG_UPDATE_CURRENT);
        notification = new Notification.Builder(this)
        .setContentTitle(contentTitle).setContentText(contentText)
        .setSmallIcon(bigIconID).setContentIntent(layoutIntent)
        .addAction(ppIconID, null, mIntent)
        .build();
            notification.flags |= Notification.FLAG_ONGOING_EVENT;
            mNM.notify(NOTIFICATION, notification);
}

So, when i calling showNotification() method, notification is shown, and click in it's body is working well. But when i'm clicking a button, setted with addAction, nothing changes... I mean, even that line in onReceive() isn't work:

Log.d("NOTIFICATION", "Received broadcast");

What can be wrong here? I read manuals in huge amount, but can't get it. Can somebody explain, how to get it working? Thank you!

PS When i changing addAction PendingIntent to getActivity, it works fine, btw...

I think what you're stuck with here is that the BroadcastReceiver isn't setup correctly. I'd actually suggest using a Service instead of a BroadcastReceiver, just due to latency of the BroadcastReceiver (at the same time, it should happen soon enough that it's likely not a big deal).

Do you have the BroadcastReceiver setup correctly in your Manifest?

Are you able to create an activity that just invokes the BroadcastReceiver (to verify that it's working correctly)?
