设备状态未更改为静默模式

Question

我最近在做一个小项目，我遇到了一个小问题。

出现问题：从其他设备发送消息时，设备状态未更改为静默模式。

工作流程：

短信包含从另一个设备发送的"Msilent">受害者设备接收短信并读取字符串并识别关键字"Msilent">受害者电话振铃配置文件更改为静音模式。

设备安卓版本：棒棒糖5.0

这是我的代码：

    public void onReceive(Context context, Intent intent) {
        maudio=(AudioManager) context.getSystemService(AUDIO_SERVICE);
        Bundle myBundle = intent.getExtras();
        SmsMessage[] messages = null;
        String strMessage = "";
        if (myBundle != null) {
            Object[] pdus = (Object[]) myBundle.get("pdus");
            messages = new SmsMessage[pdus.length];
            for (int i = 0; i < messages.length; i++) {
                String format = myBundle.getString("format");
                messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i], format);
                /*strMessage += messages[i].getOriginatingAddress();
                strMessage += " : ";*/
                strMessage += messages[i].getMessageBody();
               // strMessage += "n";
            }
            Log.v("SMS", strMessage);
            if (strMessage.contains("Msilent"))
                maudio.setRingerMode(AudioManager.RINGER_MODE_SILENT);
            Toast.makeText(context, strMessage, Toast.LENGTH_SHORT).show();
        }
    }
}
