android studio tutorial for beginners 2015

So let’s start the adventure! I’ve broken down what we need to do into 7 simple steps (from which the 5th one „Write new code” is much longer than the others, as it contains the key part of this tutorial). However, adding multithreading and asynchronity to the app would bring in more complexity, so I left them out for now.

For example, all our code is synchronous and runs within the UI thread, that is something you don’t want to do in a „serious” app, as network can be really slow and it should be avoided that the app looks to be frozen. In comparison, this post contains a code snippet that just wants to be short and simple, so please don’t criticize the shortcuts, they are inten ded. It contains nicely designed and comprehensive code, from which you can learn a lot. They are all great, for example Claudia Pacheco’s „How To…Consume OData Services in Online Mode (Android)” tutorial (available here: ) is really excellent. There is already plenty of other material available covering learning OData SDK for Android.

The only prerequisites are basic knowledge of Java programming, the Android SDK, RESTful web services and the OData protocol, as well as Android Studio and SAP Mobile SDK being installed on your developer PC, the latter being downloadable from the location specified in this article at the time of writing this post. Around the code, I try to provide as much explanation as possible, so that anyone new to the topic can understand. You can call it the „Hello World” for OData on Android. In this tutorial, my intention is to introduce the SAP Mobile Platform SDK for Android, Harmonized OData API online store concept to you with a code snippet altogether 31 lines long.
