When I launch the emulator I face many problems (Errors):-
HttpConnectionApp]emulator-5554 disconnected!
Cancelling 'net.paxcel.http.HttpConnectionApp activity launch'!
Emulator]emulator: ERROR: the user data image is used by another emulator.
aborting
Each time I have to re-run it but all in vain.
How can I improve this so that I can re-run the application on same AVD?
I had the same issue after my computer locked up and I had to power cycle it.
Wiping the user data didn't fix my problem, I had to delete the following folders manually
C:\Users\%UserName%\.android\avd\AVD2.1.avd\cache.img.lock
C:\Users\%UserName%\.android\avd\AVD2.1.avd\userdata-qemu.img.lock
Here is the answer that helped me: link text
Another solution for me is start the avd manager and start once emulator from there. After that everything turns to normal.
This can also happen if you're using a network share as your home folder, because some network file sharing systems may lock the image files.
