Ringtone lost after enable/disable silent mode
<p>I made a code that applies a ringtone. The ringtone is applied, however, when I go in and put Android enable/disable silent mode by press power button, the system does not return to the Ringtone that was assigned...</p>

<p>Difference has the use of context types in this case?</p>

<pre><code>RingtoneManager.setActualDefaultRingtoneUri(this, RingtoneManager.TYPE_RINGTONE, newUri);
</code></pre>

<p>Thanks!</p>
