After updating SDK for android L Preview, i tried to update ADT to 23 from adt 22 but it said version conflict.so couldnot able to update the ADT then i uninstalled the ADT plugin via about eclipse, after restarting eclipse was not opening up, it show the alert as Application "Eclipse" can't be opened. -10810
This happened to me when dealing with the latest Development Tools version 23 problem with Eclipse and the Android Development Tools as noted in this article.
The easiest solution I had found when getting to this state was just to re-download the ADT package for Android development once again and install over the previous build. This will NOT keep all the plug-ins/workspace/projects that you had in a previous state, but will get you back into working condition. All SVN repositories can re-connect however.
