Error in eclipse when running activity

I am starting to program for android, when I first try to run the application from eclipse IDE it worked fine, but now I am getting the following error:

emulator: ERROR: unexpected qemud char. channel close

I didn't change the configuration or the code i had, also the acti开发者_如何学Govity is not starting in the emulator and I can't debug.

Can someone tell me what this error means?

Thanks

you may try to delete the AVD & create a new one sometimes it keeps saving errors in a log then those errors become permanent try to create a new emulator then test again
