Interprocess Communication (IPC) on Android is facilitated in a number of different ways.  The binder functions as follows:

 

  • State: RECEIVE blocked.  Go to READY when another process sends a message to this process.
  • State: READY.  Go to RECEIVE blocked if we receive a message, SEND blocked if we send a message, and maintain this state for reply or error.
  • State: SEND blocked.  Go to REPLY blocked when another process receives our message.
  • State: REPLY blocked.  Go to READY when another process replies or returns an error.

 

Android has an object that controls this communication.
