android eclipse 開發中遇到 Cannot connect to VM

'Launching ????' has encountered a problem. Cannot connecto to VM

Socket operation on nonsocket: configureBlocking




It caused by having a "main" method.
Delete/rename the method and then go to the properties of the project.
Click "Run/Debug Settings" and delete the class (it may make eclipse to run the class after being compiled).


I had to change the Test Launcher being used.

Run->Debug Configurations->JUnit->*JUnit Test Class*Choose Select Other in the bottom left of the settings dialog, next to the menu list.
