Parse SDK implement custom BroadcastReceiver for push notifications in android

Here's an example!

public class ParseCustomBroadcastReceiver extends ParsePushBroadcastReceiver {

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

            JSONObject json = new JSONObject(intent.getExtras().getString("com.parse.Data"));
            Log.d(TAG, json.getString("alert").toString());

            final String notificationTitle = json.getString("title").toString();
            final String notificationContent = json.getString("alert").toString();
            final String uri = json.getString("uri");             

            Intent resultIntent = null;
            TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);


                resultIntent = new Intent(context, HomeScreen.class);
                stackBuilder.addParentStack(HomeScreen.class);

            stackBuilder.addNextIntent(resultIntent);
            PendingIntent resultPendingIntent =
                    stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);


//Customize your notification - sample code
            NotificationCompat.Builder builder =
                    new NotificationCompat.Builder(context)
                            .setSmallIcon(R.mipmap.ic_notification_icon)
                            .setContentTitle(notificationTitle)
                            .setContentText(notificationContent);

            int mNotificationId = 001;
            NotificationManager mNotifyMgr =
                    (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
            mNotifyMgr.notify(mNotificationId, builder.build());


        } catch (JSONException e) {
            Log.d(TAG, e.getMessage());
        }

    }
}

Following this guide, replace android name for the receiver to the path of your custom broadcastreceiver

<receiver
            android:name=".receivers.ParseCustomBroadcastReceiver"
            android:exported="false" >
            <intent-filter>
                <action android:name="com.parse.push.intent.RECEIVE" />
                <action android:name="com.parse.push.intent.DELETE" />
                <action android:name="com.parse.push.intent.OPEN" />
            </intent-filter>
        </receiver>

In your application class, make sure to have subscribed to Parse Push like this

Parse.initialize(this, ParseUtils.PARSE_APPLICATION_ID_DEV, ParseUtils.PARSE_CLIENT_KEY_DEV);
        ParseObject.registerSubclass(Article.class);

        ParsePush.subscribeInBackground("", new SaveCallback() {
            @Override
            public void done(ParseException e) {
                if (e == null) {
                    Log.d(TAG, "successfully subscribed to the broadcast channel.");
                } else {
                    Log.e(TAG, "failed to subscribe for push", e);
                }
            }
        });

Update:

The above broadcast receiver expects to send a json object notification from parse dashboard usually consists of three name value pairs:

{ "alert": "Alert message", "title": "Title", "uri": "bla bla" } 

When you use only plain string for eg: hello world! in parse push dashboard, internally it goes as only alert tag. something like this : {"alert" : "hello world!, "title" = null/"", "uri" = null/""}

The broadcast receiver code above doesn't have this null checks, so it's caught in the catch with exception No title/uri.

So you can add some null checks based on what you are expecting from the push notification.

Something like this:

JSONObject json = new JSONObject(intent.getExtras().getString("com.parse.Data"));
            Log.d(TAG, json.getString("alert").toString());

            if (json.has("title")) {
                 notificationTitle = json.getString("title").toString();
            }
            if (json.has("alert")) {
                 notificationAlert = json.getString("alert").toString();
            }

            if(json.has("uri")) {
                notificationURI = json.getString("uri");
            }

Then set appropriate contentTitle and contentText in notification

 NotificationCompat.Builder builder =
                    new NotificationCompat.Builder(context)
                            .setSmallIcon(R.mipmap.ic_launcher)
                            .setContentTitle(notificationAlert)
                            .setContentText(notificationAlert);

Hope this helps!
