android 通话录音实现

因受系统限制，只能录自已麦的声音，录不到对方的声音，可能需要改内核才能实现双向录音；

接通电话和挂断电话时，震动一下；

使用广播接收者实现自启动； 

 

服务代码：

通过广播接收者实现自启动，代码：

 
  package com.eboy.phoneListener; 
  

import android.content.Context; 
  
import android.content.Intent; 
  

public  
  class BroadcastReceiver  
  extends android.content.BroadcastReceiver { 
  

    @Override 
  
     
  public  
  void onReceive(Context arg0, Intent arg1) { 
  
        Intent service =  
  new Intent(arg0, phoneService. 
  class); 
  
        arg0.startService(service); 
  
    } 
  
}
