The K2 compiler brings substantially faster compilation times, especially in large multi-module... Continue reading →

Now, we are going to create our first Android app in the Android development tutorial series. I assume that you've already setup a complete Android development environment and has a basic knowledge on Android application components and activity lifecycle. Its a longstanding tradition that when learning a new programming language or a framework, the first program written is to display a "Hello... Continue reading →

In this article, we will examine the Android project structure and file organization in detail, by creating a new Android project in Eclipse. Before that, it will be better to read my earlier post on how to setup a complete Android development environment in the Android development tutorial series. When we start a new Android project in Eclipse, it will automatically creates a lot of files and... Continue reading →

This is my third and final post in the Android key concepts series and the most important one, I think. In this article, we will explore the Android activity lifecycle and various event handlers associated with each stage changes. If you don't know what an Activity in Android is, go to Android application components first. We know how an application behaves in desktop platforms like Windows,... Continue reading →
