Android Development's method of shutting down and opening speaker (loudspeakers) _android

The examples in this article describe the way Android developed to turn off and turn on speaker (speakers). Share to everyone for your reference, specific as follows:

private int currvolume = 0; /** * Open Speaker */private void Openspeaker () {try{Audiomanager Audiomanager = (audiomanager) getsystemservice (Con Text.
      Audio_service);
      Audiomanager.setmode (Audiomanager.route_speaker);
      Currvolume = Audiomanager.getstreamvolume (Audiomanager.stream_voice_call);
        if (!audiomanager.isspeakerphoneon ()) {//setspeakerphoneon () is work when audio mode set to Mode_in_call.
        Audiomanager.setmode (Audiomanager.mode_in_call);
        Audiomanager.setspeakerphoneon (TRUE); Audiomanager.setstreamvolume (Audiomanager.stream_voice_call, Audiomanager.getstreammaxvolume (AudioManager.STRE
      Am_voice_call), Audiomanager.stream_voice_call);
    } catch (Exception e) {e.printstacktrace (); }/** * Shut down speaker/public void Closespeaker () {try {Audiomanager Audiomanager = (audiomanager) Getsystemservic
      E (Context.audio_service); if (Audiomanager!= null) {if (audiomanager.isSpeakerphoneon ()) {Audiomanager.setspeakerphoneon (false);
        Audiomanager.setstreamvolume (Audiomanager.stream_voice_call,currvolume, Audiomanager.stream_voice_call);
    A catch (Exception e) {e.printstacktrace ());

 }
}
