Android Development Voice Wakeup function

Scene: After entering the program in the voice wake state, when speaking of a keyword to open a sub-interface (such as: Speech recognition interface)

Technical points:

1.

Set wake up until Stoplistening is called, incoming 0 completes a wake-up session immediately ends (default 0)
Mivw.setparameter (Speechconstant.keep_alive, "1");

2. Add resource file Appid.jet It's weird why there's no need for a grammar file in this demo.

Key code:
