android 去电监听录音（通过广播和服务）

通过广播，实现去电监听，通过服务实现录音。

开发工具：Android Studio 3.0.1

看代码：

broadcastReceiver.java

package com.example.test_6application;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.widget.Toast;public class broadcastReceiver extends BroadcastReceiver {    @Override    public void onReceive(Context context, Intent intent) {        // TODO: This method is called when the BroadcastReceiver is receiving        // an Intent broadcast.        //throw new UnsupportedOperationException("Not yet implemented");        if (intent.getAction().equals("android.intent.action.NEW_OUTGOING_CALL")) {            String phoneNum = intent.getStringExtra( Intent.EXTRA_PHONE_NUMBER );            Toast.makeText( context, "监听到拨打电话:" +phoneNum , Toast.LENGTH_SHORT ).show();            //其他操作，如启动另一个Activiy：            //Intent it = new Intent( context, ***Activity.class );            //context.startActivity(it);            Intent it = new Intent( context,recordService.class );            context.startService(it); //启动录音服务        }    }}

//先创建一个广播

再创建一个服务(recordService.java)

//使用MediaRecorder类实现录音

源码：

package com.example.test_6application;import android.app.Service;import android.content.Intent;import android.media.MediaRecorder;import android.os.IBinder;import java.io.File;import java.io.IOException;import java.text.SimpleDateFormat;import java.util.Date;public class recordService extends Service {    private File recordFile;    // 录音类    private MediaRecorder mediaRecorder;    public recordService() {    }    @Override    public IBinder onBind(Intent intent) {        // TODO: Return the communication channel to the service.        throw new UnsupportedOperationException("Not yet implemented");    }    @Override    public void onCreate() {        super.onCreate();    }    @Override    public int onStartCommand(Intent intent, int flags, int startId) {        SimpleDateFormat formatter  = new  SimpleDateFormat    ("yyyy年MM月dd日    HH:mm:ss     ");        Date curDate  =  new  Date(System.currentTimeMillis());//获取当前时间        String  str  = formatter.format(curDate);        // recordFile = new File("/sdcard", "kk.amr");        recordFile = new File("/sdcard/"+"_"+str+".3gp");        mediaRecorder = new MediaRecorder();        // 判断，若当前文件已存在，则删除        if (recordFile.exists()) {            recordFile.delete();        }        mediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);//设置音频输入源 ,麦克风        mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.DEFAULT); //设置音频输出格式   three_gpp        mediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT);//设置音频编码方式   amr_nb        mediaRecorder.setOutputFile(recordFile.getAbsolutePath());        try {            // 准备好开始录音            mediaRecorder.prepare();            mediaRecorder.start();        } catch (IllegalStateException e) {            // TODO Auto-generated catch block            e.printStackTrace();        } catch (IOException e) {            // TODO Auto-generated catch block            e.printStackTrace();        }        return super.onStartCommand(intent, flags, startId);    }    @Override    public void onDestroy() {        if (recordFile != null) {            mediaRecorder.stop();            mediaRecorder.release();        }        super.onDestroy();    }}

创建方法：

android 去电监听录音（通过广播和服务）_第4张图片

MainActivity.java

android 6.0以上要获取手机打电话、录音、存储权限，及以下代码的3个 if 条件语句

注意要引入 v4-27.1.1 包

activitymain.xml

<?xml version="1.0" encoding="utf-8"?>

manifests.xml

添加权限：去电权限、写入sd卡权限等

添加广播监听权限：

<?xml version="1.0" encoding="utf-8"?>

本人使用android 6.0手机，能够正确运行录音
