In this tutorial I’ll show you how to fix Android Studio errors that you guys are having trouble with. I’ll also show how to pass objects between screens in Android.

I show how to set up Android Studio 0.8, show the files you need to install in the SDK Manager, and how to set up a working Android Virtual Device. I’ll also show how to fix the UIDs are inconsistent error. You can download Android Studio here. All the code used follows the tutorial below.
