Using broadcast in Android

Question

Anybody knows how to use sendBroadcast and BroadcastReceiver for different application? Actually I have already used sendBroadcast and BroadcastReceiver but in the same project. Now I want to try to send to another application. Anybody knows?

In my previous project I broadcast like this in mainActivity:

Intent broadCastIntent = new Intent("SendMessage");
broadCastIntent.putExtra("NAME", gameName);
broadCastIntent.putExtra("JOB",jobStatus);
broadCastIntent.putExtra("STATUS",gameStatus);
sendBroadcast( broadCastIntent );
Log.d("Broadcast sent", gameName );

Also I add method to check the intent:

protected void onResume()
    {

        if (receiver == null)
        {
            receiver = new myBroadcastReceiver(); --> Here I call the receiver from another package
        }
        registerReceiver(reciever, new IntentFilter("SendMessage"));

    }

    @Override
    protected void onPause()
    {
        super.onPause();
        unregisterReceiver(reciever);
    }

And in another package but in one project , I have created myBroadcastReceiver class for Receive the intent:

public class myBroadcastReceiver extends BroadcastReceiver 
{

    @Override
    public void onReceive(Context context, Intent intent) {

        String status = intent.getStringExtra("STATUS");
        String job = intent.getStringExtra("JOB");
        String media = intent.getStringExtra("MEDIA");
        GameWorldExtension.job = job;
        GameWorldExtension.media = media;
        GameWorldExtension.status = status;
        Log.d("receiver", "Got message: " + GameWorldExtension.status);
    }

}

I have try and it works fine. Right now I want to try to send into another application. I have tried many ways, but it didn't successful. Anybody knows how to send in right order?Thanks

I think this post could help you. There is an example of BroadcastReceiver that listening "onWifiChange" event. How to use Broadcast Receiver in different Applications in Android?

On Sender side:

1) Sender class:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Intent intent = new Intent("pacman.intent.action.BROADCAST");
    intent.putExtra("message","Wake up.");
    sendBroadcast(intent);
}

On Receiver side:

1) Receiver class:

public class MyBroadcastReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        System.out.println("Message at Pacman received!");
    }
}

2) Receiver manifest file:

<receiver android:name="com.ex.myapplication2.MyBroadcastReceiver">
    <intent-filter>
        <action android:name="pacman.intent.action.BROADCAST" />
    </intent-filter>
</receiver>

Hi someGuy, thank you for your answer. As I see from example "onWifiChange" I couldn't find how the intent is broadcasted. I would like to know both ways, how to send and received it. — eng, Oct 18 '13 at 08:12
