In Android I have a service (started through standard startService call). The application is referencing a library JAR file. The first Activity sets a static boolean field to "true", then in the service process, I see that this value is true as well.

How can this be?

The service is started after the value is set -- could it be that the DVM copies the static state when the service process is created, or are static fields shared between processes? I was under the impression that a separate VM was launched for each process.

假设您的 Activity 和 Service 在同一个应用程序中，它们在同一个进程下的两个独立线程中运行。因此，您应该期望它们共享您引用的静态变量的相同实例。

对不起，我在欺骗自己。尽管该服务在一个单独的进程中（使用android:process清单中的属性），但我不小心调用了执行此操作的代码。
