Audiomanager

public void Setstreammute (int streamtype, Boolean state)

Mute or not mute the audio stream.

Mute commands are protected from client process death: If the process dies with an active mute request on the stream, the stream is automatically muted.

For a given stream, the mute request is cumulative: Audiomanager receives several mute requests from one or more clients, and the mute is Shireu only if the same number of cancellation requests is received.

For a better user experience, the program must remove the muted stream from the OnPause (), if appropriate, mute again in Onresume ()

This method can be used only for platform-wide management applications or primary telephony applications that replace audio settings.

Parameters

Streamtype to Mute/cancel the quiet stream.

State Requests Mute Status: If true, mute, and if false, suppress mute.

If you use the mode associated with the phone vibration, remember to add permissions. Android.permission.VIBRATE Oh!
