Android 自动接听电话和挂断

来源:互联网 发布:云南广电网络营业厅 编辑:程序博客网 时间:2024/04/28 15:37

注意:android2.3版本及以上不支持下面的自动接听方法。(会抛异常:java.lang.SecurityException: Neither user xxxxx nor current process has android.permission.MODIFY_PHONE_STATE.)

原因:android2.3版本及以上android.permission.MODIFY_PHONE_STATE权限限制已经改为系统权限。

        普通应用程序已经无法调用,所以网上找到的那些如何使用android.permission.MODIFY_PHONE_STATE的文章均已失效,但仍有引用的办法就是让你的程序程序系统程序。一种就是预制到ROM中,另一种就是使用系统签名。第一种已经试验通过(按下面步骤进行),第二种还有待验证。

1、把编译好的apk放入sd卡,2、用root explorer复制到/system/app目录下,3、修改apk权限rw-r--r--,关机,重启,测试一下,成功! 注意:只能在root的手机上使用

使用映射机制实现自动接听和挂断

第一步:准备应用环境需要的系统包和aidl文件。

(1)在应用中创建包:android.telephony

         将android系统框架下的\framework\telephony\java\android\telephony目录中的NeighboringCellInfo.aidl文件复制到上面创建的包(android.telephony )中;

(2)在应用中创建包:com.android.internal.telephony

         将android系统框架下的\framework\telephony\java\com\android\internal\telephony目录中的ITelephony.aidl文件复制到上面创建的包(com.android.internal.telephony )中;

第二步:创建一个获取ITelephony的方法

PhoneUtils.java

package com.moho.telephone.utils;import java.lang.reflect.Method;import com.android.internal.telephony.ITelephony;import android.telephony.TelephonyManager;/**
 * moho
 */public class PhoneUtils {public static ITelephony getITelephony(TelephonyManager telephony) throws Exception {Method getITelephonyMethod = telephony.getClass().getDeclaredMethod("getITelephony");getITelephonyMethod.setAccessible(true);//私有化函数也能使用return (ITelephony)getITelephonyMethod.invoke(telephony);}}


第三步:创建电话广播拦截器

MyPhoneBroadcastReceiver.java
import com.android.internal.telephony.ITelephony;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.telephony.TelephonyManager;import android.util.Log;public class MyPhoneBroadcastReceiver extends BroadcastReceiver {private final static String TAG = MyPhone.TAG;@Overridepublic void onReceive(Context context, Intent intent) {String action = intent.getAction();Log.i(TAG, "[Broadcast]"+action);//呼入电话if(action.equals(MyPhone.B_PHONE_STATE)){Log.i(TAG, "[Broadcast]PHONE_STATE");doReceivePhone(context,intent);}}public void doReceivePhone(Context context, Intent intent) {String phoneNumber = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);TelephonyManager telephony = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);int state = telephony.getCallState();switch(state){case TelephonyManager.CALL_STATE_RINGING:Log.i(TAG, "[Broadcast]等待接电话="+phoneNumber);try {ITelephony iTelephony = PhoneUtils.getITelephony(telephony);iTelephony.answerRingingCall();//自动接通电话//iTelephony.endCall();//自动挂断电话} catch (Exception e) {Log.e(TAG, "[Broadcast]Exception="+e.getMessage(), e);}break;case TelephonyManager.CALL_STATE_IDLE:Log.i(TAG, "[Broadcast]电话挂断="+phoneNumber);break;case TelephonyManager.CALL_STATE_OFFHOOK:Log.i(TAG, "[Broadcast]通话中="+phoneNumber);break;}}}

第四部:注册电话广播拦截器

MyPhone.java
import android.app.Activity;import android.content.IntentFilter;import android.os.Bundle;import android.telephony.TelephonyManager;import android.util.Log;import android.view.View;public class MyPhone extends Activity {public final static String TAG = "MyPhone";public final static String B_PHONE_STATE = TelephonyManager.ACTION_PHONE_STATE_CHANGED;private MyPhoneBroadcastReceiver mBroadcastReceiver;@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.my_phone);}//按钮1-注册广播public void registerThis(View v) {Log.i(TAG, "registerThis");mBroadcastReceiver = new MyPhoneBroadcastReceiver();IntentFilter intentFilter = new IntentFilter();intentFilter.addAction(B_PHONE_STATE);intentFilter.setPriority(Integer.MAX_VALUE);registerReceiver(mBroadcastReceiver, intentFilter);}//按钮2-撤销广播public void unregisterThis(View v) {Log.i(TAG, "unregisterThis");unregisterReceiver(mBroadcastReceiver); } }

第5步:在AndroidManifest.xml配置权限
Xml代码
<uses-permission android:name="android.permission.READ_PHONE_STATE" /><uses-permission android:name="android.permission.MODIFY_PHONE_STATE" /><uses-permission android:name="android.permission.CALL_PHONE"/>
其中:


iTelephony.answerRingingCall();//自动接通电话
必须有权限 android.permission.MODIFY_PHONE_STATE


iTelephony.endCall();//自动挂断电话
必须有权限 android.permission.CALL_PHONE


因为Android2.3以上增加了对permission android.permission.MODIFY_PHONE_STATE 的限制,2.3之前的通过反射机制调用ITelephone的能力的做法已经不适用。
2.3上实现方式:

public synchronized void answerRingingCall() {//查询系统PhoneAPP应用(PhoneGlobals.java)实现了对耳机插入、多媒体按键等通知的接受和处理。其中未发现有特殊的地方,个人认为,如果系统接收到此广播应该可以///进行接听或挂断操作。       private void answerRingingCallWithBroadcast(Context context,TelephonyManager telmanager){          AudioManager audioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);          //判断是否插上了耳机          if (! audioManager.isWiredHeadsetOn()) {        //4.1以上系统限制了部分权限, 使用三星4.1版本测试提示警告:Permission Denial: not allowed to send broadcast android.intent.action.HEADSET_PLUG from pid=1324, uid=10017//这里需要注意一点,发送广播时加了权限“android.permission.CALL_PRIVLEGED”,则接受该广播时也需要增加该权限。但是4.1以上版本貌似这个权限只能系统应用才可以//得到。测试的时候,自定义的接收器无法接受到此广播,后来去掉了这个权限,设为NULL便可以监听到了。        if(android.os.Build.VERSION.SDK_INT >=15 ){                Intent meidaButtonIntent = new Intent(Intent.ACTION_MEDIA_BUTTON);                  KeyEvent keyEvent = new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_HEADSETHOOK);                  meidaButtonIntent.putExtra(Intent.EXTRA_KEY_EVENT,keyEvent);                  context.sendOrderedBroadcast(meidaButtonIntent, null);          }else{// 以下适用于Android2.3及2.3以上的版本上 ,但测试发现4.1系统上不管用。        Intent localIntent1 = new Intent(Intent.ACTION_HEADSET_PLUG);                  localIntent1.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);                  localIntent1.putExtra("state", 1);                  localIntent1.putExtra("microphone", 1);                  localIntent1.putExtra("name", "Headset");                  context.sendOrderedBroadcast(localIntent1,  "android.permission.CALL_PRIVILEGED");                                  Intent localIntent2 = new Intent(Intent.ACTION_MEDIA_BUTTON);                  KeyEvent localKeyEvent1 = new KeyEvent(KeyEvent.ACTION_DOWN,   KeyEvent.KEYCODE_HEADSETHOOK);                  localIntent2.putExtra(Intent.EXTRA_KEY_EVENT,   localKeyEvent1);                  context. sendOrderedBroadcast(localIntent2,  "android.permission.CALL_PRIVILEGED");                                 Intent localIntent3 = new Intent(Intent.ACTION_MEDIA_BUTTON);                  KeyEvent localKeyEvent2 = new KeyEvent(KeyEvent.ACTION_UP,  KeyEvent.KEYCODE_HEADSETHOOK);                  localIntent3.putExtra(Intent.EXTRA_KEY_EVENT,  localKeyEvent2);                  context.sendOrderedBroadcast(localIntent3,   "android.permission.CALL_PRIVILEGED");                                  Intent localIntent4 = new Intent(Intent.ACTION_HEADSET_PLUG);                  localIntent4.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);                  localIntent4.putExtra("state", 0);                  localIntent4.putExtra("microphone", 1);                  localIntent4.putExtra("name", "Headset");                  context.sendOrderedBroadcast(localIntent4, "android.permission.CALL_PRIVILEGED");        }                      } else {              Intent meidaButtonIntent = new Intent(Intent.ACTION_MEDIA_BUTTON);              KeyEvent keyEvent = new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_HEADSETHOOK);              meidaButtonIntent.putExtra(Intent.EXTRA_KEY_EVENT,keyEvent);              context.sendOrderedBroadcast(meidaButtonIntent, null);          }      }
