/**
|

* This is a quick-and-dirty sound trigger HAL console mock.
|
||||
*
|
||||
* It would only work on userdebug builds.
|
||||
*
|
||||
* When this app is started, it will initially:
|
||||
* - Register a ISoundTriggerHw HAL with an instance name "mock".
|
||||
* - Set a sysprop that tells SoundTriggerMiddlewareService to try to connect to the mock instance
|
||||
* rather than the default one.
|
||||
* - Reboot the real (default) HAL.
|
||||
*
|
||||
* In response to that, SoundTriggerMiddlewareService is going to connect to the mock HAL and resume
|
||||
* normal operation.
|
||||
*
|
||||
* Our mock HAL will print to stdout every call it receives as well as expose a basic set of
|
||||
* operations for sending event callbacks to the client. This allows us to simulate the frameworks
|
||||
* behavior in response to different HAL behaviors.
