关闭随机拨打电话的声音

经过长时间的搜索，我无法解决我的问题。关闭随机拨打电话的声音

在我的应用程序中，我想用白名单默默控制来电号码。

这是使用的代码，有时它是完美的，但不是每次都有效。振铃模式已恢复，我可以控制它，当我推动上限或下限音量控制，但没有声音输出到设备。

手机响铃时是否可以更改铃声模式？我的测试是在S3 4.3

感谢您的时间来帮助我。

代码：

// Disable ringtone & vibration 
AudioManager am = (AudioManager) getBaseContext().getSystemService(Context.AUDIO_SERVICE); 
int ringerMode = am.getRingerMode(); 
am.setRingerMode(AudioManager.RINGER_MODE_SILENT); 

... doing something ... 

// Restore ringtone settings after check 
am.setRingerMode(ringerMode);
