问题
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:
java.lang.NullPointerException

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?
回答1:
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.

回答2:
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.
回答3:
This is a bug. A possible workaround is to clone an existing device definition (e.g. Nexus 7) and set it to your required parameters.
回答4:
Try this (Considering that the cause is a corrupted config for an existing AVD):
Go to ~/.android/avd
Check the list of AVDs. If you think one of those AVDs is causing the problems, sudo rm -r (UNIQUE PART OF AVD NAME)*
This removes that AVD. Then re-try android avd
