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); } }
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; @Override public 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; } } }
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; @Override public 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); } }
<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); } }
