cannot connect to VM
提问by Kat
I made a test class in my android project to check if my database works. But when I want to debug this class it gives me an error: "Cannot connect to VM", in details it says also "Socket operation on nonsocket: configureBlocking". When I try debugging a test class in another project it works and debugging my other classes in the android project also works. Can the problem be that I try to run a normal test on an android project?
我在我的 android 项目中做了一个测试类来检查我的数据库是否工作。但是当我想调试这个类时，它给了我一个错误：“无法连接到 VM”，详细地说它也说“非套接字上的套接字操作：configureBlocking”。当我尝试在另一个项目中调试测试类时，它可以工作，并且在 android 项目中调试我的其他类也可以工作。问题可能是我尝试在 android 项目上运行正常测试吗？
Can someone help me? Thanks!

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).
它是由具有“主要”方法引起的。
删除/重命名方法，然后转到项目的属性。
单击“运行/调试设置”并删除该类（可能会使 eclipse 编译后运行该类）。
