IBinder methods must, therefore, be implemented to be thread-safe.
因此ibinder方法必须实现为线程安全的。
Because a service can have more than one client, more than one pool thread can engage the same IBinder method at the same time.
因为一个服务可以有不止一个客户端，所以同时可以有多个线程池与同一个IBinder方法相关联。
When a call on a method implemented in an IBinder originates in the same process in which the IBinder is running, the method is executed in the caller's thread.
如果对IBinder所实现方法的调用发起于IBinder所在进程的内部，那么这个方法是执行在调用者的线程中的。
