Error: the user data image is used by another emulator. Aborting

At first, I thought it was a problem that the program was not re-compiled. I cleaned the project, but this problem still occurred.

Later, I found the cause on the Internet and found the corresponding solution, which is very simple.

The reason is:If you didn't shut down the simulator normally last time, it will lock the simulator by default or it is running, and the resource is occupied

 

Solution: first enter the directory:
/Documents and Settings/user/. Android/AVD/* Device */(for example, my directory is: C:/Documents ents and settings/Administrator/. Android/AVD/android2.0.avd)
Then delete. the folder at the end of lock (I will explain why to delete these files, in fact. lock is a lock. If the program crashes or other causes, it cannot be cleared. this problem occurs in the folder at the end of lock, that is, the AVD lock is not released, causing AVD manager to think that the AVD is in use .)
