Android. Record calls, disable mic. Acer Ferrari
<p>My app needs to record calls.
It works fine on many devices, but not on Acer Ferrari Liquid E.
If my app is running, then interlocutor on other side of wire does not hear me (if I set mic on/off manually, then he hear me).
So, as workaround for Ferrari, I want to try set on/off mic programmaticaly.</p>

<pre><code>(AudioManager)getApplicationContext()
  .getSystemService(Context.AUDIO_SERVICE)
  .setMicrophoneMute
</code></pre>

<p>does not work.</p>
