Reduce volume of received call's ringtone?
<p>I want to lower the  volume in in-call mode 
So I tried this code:</p>

<pre><code>AudioManager audio = (AudioManager)getSystemService(Context.AUDIO_SERVICE);
audio.setStreamVolume(audio.STREAM_VOICE_CALL, -1, 0);
</code></pre>

<p>But In-call volume is set to 0 and still loud.
Have any idea? I don't want to set the mode of ringtone to silent, just turned down.</p>
