To make an Android app effective and successful, it needs to be integrated with many different third party services. This will deliver the best services and experience to the end-user. To make Android apps more versatile, we integrate apps with many other external systems. One of the most common ways to integrate is with payment gateways such as PayPal and Authorize.net. We use Firebase & Urban Airship for push notifications. Thus, the apps could deliver relevant information bringing the attention of the end-user to increase the effectiveness of the application.
