本文深入探讨了Android系统中关键的Binder通信机制，解释了Binder Write Read、Set Wakeup Time、Set Idle Timeout、Set Reply Timeout和Set Max Threads等核心功能的作用与应用，为开发者提供了一个全面的指南。

BINDER_WRITE_READ sends zero or more Binder operations, then blocks waiting to receive incoming operations and return with a result. (This is the same as doing a normal write() followed by a read() on the file descriptor, just a little more efficient.)

BINDER_SET_WAKEUP_TIME sets the time at which the next user-space event is scheduled to happen in the calling process.

BINDER_SET_IDLE_TIMEOUT sets the time threads will remain idle (waiting for a new incoming transaction) before they time out.

BINDER_SET_REPLY_TIMEOUT sets the time threads will block waiting for a reply until they time out.

BINDER_SET_MAX_THREADS sets the maximum number of threads that the driver is allowed to create for that process's thread pool.
