Using Broadcast Recceiver for all Activities in app

Question

I am using BroadCast Receiver in my app. I have many activities in my app. Used broadcard receiver in MainActivity.java as below :

private BroadcastReceiver smsReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        // Retrieves a map of extended data from the intent.
        final Bundle bundle = intent.getExtras();
        try {
            if (bundle != null) {

            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
};

I am notifying when message is coming and MyActivity is in focus. Now When my other activites are in focus i am not getting notified. Is there a common way to use BroadCast thing as global way ??? for all activities ???

Answer 1

Broadcast receiver always be their util you unregister broadcast receiver.

For solving your problem you have to register broadcast on application level.

Eg :

public MyApplication extends Application 
{
    onCreate() {
        // register broadcast receiver here
    }

    private BroadcastReceiver smsReceiver = new BroadcastReceiver() 
    {
        @Override
        public void onReceive(Context context, Intent intent) {
            // Retrieves a map of extended data from the intent.
            final Bundle bundle = intent.getExtras();
            try {
                if (bundle != null) {
                }
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    };
}

After that you can perform any action at any time as now broadcast receiver on application level. Also you will not face any memory leak inside activity.
