Question

我最近一直在做一个小项目，我遇到了一个小问题。

问题出现： 从其他设备发送消息时，设备状态不会更改为静默模式。

工作流：

短信包含＆＃34; Msilent＆＃34;从另一个设备发送＆gt; 受害者设备接收短信并读取字符串并识别关键字＆＃34; Msilent＆＃34; ＆GT; 受害者电话响铃配置文件变为静音模式。

设备Android版：Lollipop 5.0

以下是我的代码：

IncomingSms.java

package android.yu;

/**

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.media.AudioManager;
import android.os.Bundle;
import android.telephony.SmsMessage;
import android.util.Log;
import android.widget.Toast;


import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Build;
import android.os.Bundle;
import android.telephony.SmsMessage;
import android.util.Log;
import android.widget.Toast;

import static android.content.Context.AUDIO_SERVICE;

/**

public class IncomingSms extends BroadcastReceiver {
    private AudioManager maudio;


    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();
        }
    }
}

MainActivity.java

package android.yu;

import android.content.Context;
import android.media.AudioManager;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

    }
}

的AndroidManifest.xml
