I can't create a new emulator (Eclipse - Android)

Question

I'm trying to create a new emulator in Eclipse with Android but when I press the Ok's button error log shows this error (Unhandled event loop exception):

What can I do to solve it? I have tried many possible solutions (I tried to remove my eclipse folder and .android folder)

Further to my comment, seems post #10 in Issue 66661 that I referred to, has identical error log to yours

    ...

So it looks like you are using 22.6. Therefore just run AVD Manager from outside Eclipse until they release a 22.6.1 to fix this bug

Answer 2

Have you tried to remove android-sdk and install it again?
