How to mute a phone ringing on incoming call

Question

How can I mute Android phone ringing at an incoming call programmatically? (Like doing this by pressing power button at incoming call)?

I know about setStreamMute and adjustStreamVolume, but I think there is a better way.

Do you mean to mute the ringing audio but keep the phone ringing silently? — Stefan, Jan 22 '17 at 14:21
@AhmadAghazadeh it is not duplicate, i don't want to reject a call. — Maxim Shirokov, Jan 23 '17 at 03:47
I think you can find some info here: http://stackoverflow.com/questions/28801646/android-studio-mute-unmute-phone-help there seems to be a `setRingerMode` perhaps that will help you. — Stefan, Jan 23 '17 at 08:45

setStreamMute() is deprecated in and above Build version 23 (marshmallow). You can use adjustStreamVolume() for marshmallow and above.

public void adjustAudio(boolean setMute) {
    AudioManager audioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        int adJustMute;
        if (setMute) {
            adJustMute = AudioManager.ADJUST_MUTE;
        } else {
            adJustMute = AudioManager.ADJUST_UNMUTE;
        }
        audioManager.adjustStreamVolume(AudioManager.STREAM_NOTIFICATION, adJustMute, 0);
        audioManager.adjustStreamVolume(AudioManager.STREAM_ALARM, adJustMute, 0);
        audioManager.adjustStreamVolume(AudioManager.STREAM_MUSIC, adJustMute, 0);
        audioManager.adjustStreamVolume(AudioManager.STREAM_RING, adJustMute, 0);
        audioManager.adjustStreamVolume(AudioManager.STREAM_SYSTEM, adJustMute, 0);
    } else {
        audioManager.setStreamMute(AudioManager.STREAM_NOTIFICATION, setMute);
        audioManager.setStreamMute(AudioManager.STREAM_ALARM, setMute);
        audioManager.setStreamMute(AudioManager.STREAM_MUSIC, setMute);
        audioManager.setStreamMute(AudioManager.STREAM_RING, setMute);
        audioManager.setStreamMute(AudioManager.STREAM_SYSTEM, setMute);
    }
}

You can call this method like,

adjustAudio(true) // To mute all the system, ringer, alarm, music, notification sounds on any event like button click.

adjustAudio(false) // To unmute all the system, ringer, alarm, music, notification sounds on any event like button click.
