I'm currently an Eclipse user, and am trying to migrate to Android Studio 1.0. I've hit a bunch of problems before getting started with development, with a new project that I generated using the wizard: 1. The final entry from the Android Studio install log was: "Creating Android virtual device Unable to create a virtual device: Unable to create Android virtual device" When I created my new project I got these issues: 2. "Gradle project sync failed" 3. "Rendering problems - missing styles. Is the correct theme chosen for this layout?" 4. "compileSdkVersion android-21 requires compiling with JDK 7"
This is all without a single line of code or config by me. Where to start diagnosing this lot? (I'm running Windows 7 x64)
