title: Android Hello World in IntelliJ 12 - Cannot find android.app.Activity class
body: <p>Please see below. I have a feeling I've got the SDKs configured incorrectly, but I'm not sure how to solve it. I tried Googling for answers but no one had this exact problem.</p>
  
  <p>Do I have the wrong Java version maybe? It seems like the two SDKs might be conflicting with each other.</p>
  
  <p>I made this project via:</p>
  
  <ol>
  <li>Create New Project</li>
  <li>Android > Application Module</li>
  <li>Defaults and Finish</li>
  </ol>

  <p>Edit: See screenshot. I got it working. All I did was create a new project and re-select the Android SDK. I'm still thinking it was because I added too many SDKs/JDKs the first time. I think all you need is the Android SDK and don't need to add the normal Java one too.</p>
