Problems starting the AVD in Eclipse

Hello All!

I'm having some trouble getting the AVD to start up for the first time in Eclipse.

When I hit start in the AVD manager, I get to the "starting android emulator" dialog with the progress bar. It completes, closes, and then nothing happens. No error messages. Just crickets.

I tried right clicking on the xml document > run as > android application. It didn't work, but I did get some red error messages:

[2014-04-30 18:54:03 - DiscoBall] The connection to adb is down, and a severe error has occured. [2014-04-30 18:54:03 - DiscoBall] You must restart adb and Eclipse. [2014-04-30 18:54:03 - DiscoBall] Please ensure that adb is correctly located at '/Users/Jessica/Desktop/android_dev_environment_mac/sdk/platform-tools/adb' and can be executed.

At this point I'm thinking maybe there's a problem with whatever the initial_setup file was doing. So I moved the whole folder, re-ran initial_setup, and restarted eclipse. This time I got this in the console as soon as I started a new Project:

[2014-04-30 19:17:24 - DeviceMonitor] Connection attempts: 1

Tried to run the ADV. Same Result. Tried rightclick > run as > android app again too. No error messages this time but it still didn't do anything.

In the AVD manager I changed the ram of the device to 1024, 512, and 256, with and without the host gpu. So that's not it...

At the bottom, there's a little progress bar, the SDK content loader. It always looks like it's still loading and re-loading the same 233MB. Not sure if that has to do with anything, but it's suspicious. I'm running Mac OS10.6.8

Lots of details I know. But hopefully some of them are relevant. Anybody have any ideas? It's probably something obvious...

Thank you!

Hi Jessica, I've never come across the problem that you describe in your post, so I can't really offer a direct fix (sorry), but... have you tried using an emulator from Genymotion? (http://www.genymotion.com/) You'll be up and running in a couple of minutes... (bonus: Genymotion emulators load much faster, and are more responsive)... Best, Masum

Hi Jessica, just found out yesterday that the Genymotion emulator does have a tiny drawback: Emulator Control in the DDMS is disabled. No biggie (I guess), but just thought you should know!
