我认为这是因为您在

onStartCommand

方法中创建了

AsyncTask

。如果说它是公共的，那么它就不是局部变量。

方法局部类不能是公共的。删除公共文件。Eclipse错误消息不准确。您可以阅读关于内部类的内容

我也找不到一个地方可以让你尝试使用这门课。我认为你在错误的地方声明了它。

它说只允许抽象和最终的？为什么不在类的代码中而不是方法中创建

Asynctask

？如果要从onStart命令调用此任务，则可以添加新的

gmailsync（）.execute（params）。除非这在服务中是不可能的，但我不这么认为，因为不可能在方法中定义公共类。它可以是最终的，因为这样它就变成了一个正则变量，在这个方法之外你永远不会使用它，比如局部变量。关于抽象修饰符，我说不出为什么这里允许它，这对我来说似乎很奇怪。。。您正在尝试在方法体中定义公共类
