Android Intent filter using data path

Question

I'm making messaging app. I want to push message to specific chatroom by using broadcast. I though uri.

chat://chatroom/{room name}

And I send a message to room name 7777.

Intent intent = new Intent(ACTION_UPDATE_CHAT); intent.setData(Uri.parse("chat://chatroom/7777")); LocalBroadcastManager.getInstance(this).sendBroadcast(intent);

And I regestered a broadcastreceiver with intent filter like below.. But I can't receive message.

IntentFilter filter = new IntentFilter(ACTION_UPDATE_CHAT); filter.addDataScheme("chat"); filter.addDataAuthority("chatroom", null); filter.addDataPath("7777", PatternMatcher.PATTERN_LITERAL); LocalBroadcastManager.getInstance(context).registerReceiver(receiver, filter);

Please Help!! :)

filter.addDataPath("7777", PatternMatcher.PATTERN_LITERAL);

But If then..Every chat room receive br..

When you send broadcast,the intent action is ACTION_UPDATE_DATA,but when you receive broadcast,the intent action is ACTION_UPDATE_CHAT,maybe it's why you can't receive the message.

Thanks! For your help. I modified you mentioned. But still It's not working.

You should replace

filter.addDataPath("7777", PatternMatcher.PATTERN_LITERAL);

by

filter.addDataPath("/7777", PatternMatcher.PATTERN_LITERAL);

The change is very subtle. All I did was add a "/" before "7777". This will fix it.
