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 ???

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.

This is another solution..!! Thanks @jitesh sir – AskingToStack Apr 05 '17 at 09:10 — AskingToStack, Apr 05 '17 at 09:10

Is there a common way to use BroadCast thing as global way ?

You should register your in BroadcastReceiver instead of specific Activity

<receiver
        android:name="com.example.android.NotificationReceiver"
        android:permission="com.google.android.c2dm.permission.SEND" >
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            <category android:name="com.example.android" />
        </intent-filter>
    </receiver>

Second way: Make independent custom class of BroadcastReceiver and register/unregister in Base of all Activity
