I tried to start the emulator for API level 8, and it just shows a black screen after the ANDROID intro flashes.
I get the following error messages in the DDMS:
01-01 17:56:51.315: E/System(120): Failure starting core service

This is what I get in the console:

I think the reason for this could be a failure to sync additional jar files that I have added to the path of my source files (signpost for oAuth). Any ideas on how I can get the emulator to work ?
That means you have to close your already running Emulator, or really remove that emulator and create a new one. I don’t know which tool do you use but maybe this link helps you:
