I am completely new to Java, and Android, and eclipse. When doing the initial Hello, Android tutorial, I go to run and get the following:
WARNING: Data partition already in use. Changes will not persist!
WARNING: Cache partition already in use. Changes will not persist!
Delete that AVD and create a new one. That worked for me, and it's the simplest way, with no configuration at all.
Goto DDMS perspective, click on the down arrow next to the screen capture camera icon and select reset adb from the dropdown menu.
My apk file was not deploying either, resetting adb sorted it out. :)
Make sure that no proxy software is preventing Eclipse from connecting to the internet.
My problem was solved by doing this!
I just had the same problem, that's why I found myself here.
What I did is to run cmd then adb kill-server, then open task manager in windows and kill the emulator-x86.exe process. Then re-run the project, it should work fine.
I guess adb kill-server isn't even necessary.
