Android Workshop Part 1: Setting up

The instructions laid out below are for setting up your computer to work with Android. This includes configuring Android Studio (the IDE), and setting up a test device.

Step 1: Installing Java

Android applications are written in the Java programming language. Because of this you will need to install the Java SE Development Kit (JDK). Go the web page and download the right version for your operating system. Make sure you accept the license agreement.
