Android AVD Manager: Can't create new device definition (java.lang.NullPointerException)

Question

I'm running the newest version of Android SDK on Mac OS X 10.9.3. I haven't had the Android SDK or any other Java development environment installed on this machine before, so this could be considered a fresh install.

Nothing happens when attempting to create a new device definition using the AVD Manager, except for the following terminal output:

Here is a screenshot of the window:

I have tried running the AVD Manager by using both android avd and android sdk with the same results. I am able to create a new AVD based on a generic device definition and that's it.

Is there something wrong on my side or did I run into some sort of a bug?

Answer 1

I had the same problem on Ubuntu 14.04. Didn't find any clean solution so far, but as a workaround try to clone an existing device and then edit its properties as you wish.

Answer 2

This appears to be a bug in the framework as I ran into it using Eclipse Juno & ADT 23.0.2. Bug report is below.
