Build your first Android App.

With over one billion devices activated, Android is the best place to make apps for education, entertainment, communication or anything else you want. So if you’ve been thinking about, or simply playing with the idea of learning Android then start now. There is the easy way with the MIT App Inventor, a cloud-based tool, which means that you can build apps right in your web browser. Visit the site, follow the instructions, and start the tutorials.
For the hard way and the best, you’ll have to write your code with Java and design the layout with XML. Once your app is ready, you’ll use a build tool to compile all the project files and package them together into a .apk file that you can run on Android devices and/or submit to Google Play. All the files you used are managed by an Integrated Development Environment (IDE). The IDE is the program you will open to edit your code files and to manage your projects, just download it from Google(Android Studio) follow the instructions, and start the first tutorial for Android developers. Happy App-ing!!!
