本文所讲的内容是在Android系统中如何写程序进行电话拦截,并发出拦截提示音提醒用户,可以说此功能还是比较实用的。
1、电话拦截
这个功能大家可能都知道了,就是利用反射原理调用ITelephony的隐藏方法来实现。
2、拦截后提示忙音/空号/已关机/已停机
这个功能其实是要用到MMI指令,具体如何设置呼叫转移的指定可以参考这里 http://baike.baidu.com/view/206402.html?fromTaglist。
在本文中我们会用到“遇忙转移”的功能。中国移动的设置方式是 **67#电话号码#,取消方式为 ##67#。”无条件转移“用21代替67即可。这两个指令可以直接在手机的拨号界面输入并拨号测试。ITelephony的endcall方法挂断电话后,会提示电话忙。如果事前设置好了忙时转移到一个空号/已关机/已停机的电话号码,就会提示您拨的电话号码是空号/已关机/已停机。
其实大家可以下载 xxx卫士看下,它设置来电拒接模式后,都是会启动设置MMI指令的界面。然后再去“设置->通话设置->来电转接”,看看 “占线时转接” 设置好的电话号码,就可以知道空号/已关机/已停机对应的电话号码是什么了。
1、修改一下BLOCKED_NUMBER这个变量值,把它设置为你要测试拦截的电话号码。
2、全部功能是在一个Activity里实现的,所以大家要先运行这个Activity,然后点击“设置呼叫转移”,设置好呼叫转移后,不要关闭这个Activity,关了就拦截不了电话了。有心的朋友可以自己去写一个Service在后台运行拦截功能。
实现方式1:
代码如下:
package net.toeach.android.callforwarding;
import java.lang.reflect.Method;
import android.app.Activity;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.media.AudioManager;
import android.net.Uri;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.os.RemoteException;
import android.telephony.TelephonyManager;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import com.android.internal.telephony.ITelephony;
public class MainActivity extends Activity {
private static final String TAG = MainActivity.class.getSimpleName();
private final static int OP_REGISTER = 100;
private final static int OP_CANCEL = 200;
private final static String BLOCKED_NUMBER = "1892501xxxx";//要拦截的号码
//占线时转移,这里13800000000是空号,所以会提示所拨的号码为空号
private final String ENABLE_SERVICE = "tel:**67*13800000000%23";
//占线时转移
private final String DISABLE_SERVICE = "tel:%23%2367%23";
private IncomingCallReceiver mReceiver;
private ITelephony iTelephony;
private AudioManager mAudioManager;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
findViewById(R.id.btnEnable).setOnClickListener(new OnClickListener(){
public void onClick(View v) {
//设置呼叫转移
Message message = mHandler.obtainMessage();
message.what = OP_REGISTER;
mHandler.dispatchMessage(message);
}
});
findViewById(R.id.btnDisable).setOnClickListener(new OnClickListener(){
public void onClick(View v) {
//取消呼叫转移
Message message = mHandler.obtainMessage();
message.what = OP_CANCEL;
mHandler.dispatchMessage(message);
}
});
mReceiver = new IncomingCallReceiver();
IntentFilter filter = new IntentFilter("android.intent.action.PHONE_STATE");
registerReceiver(mReceiver, filter);// 注册BroadcastReceiver
mAudioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
//利用反射获取隐藏的endcall方法
TelephonyManager telephonyMgr = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
try {
Method getITelephonyMethod = TelephonyManager.class.getDeclaredMethod("getITelephony", (Class[]) null);
getITelephonyMethod.setAccessible(true);
iTelephony = (ITelephony) getITelephonyMethod.invoke(telephonyMgr, (Object[]) null);
} catch (Exception e) {
e.printStackTrace();
}
}
private Handler mHandler = new Handler() {
public void handleMessage(Message response) {
int what = response.what;
switch(what) {
case OP_REGISTER:{
Intent i = new Intent(Intent.ACTION_CALL);
i.setData(Uri.parse(ENABLE_SERVICE));
startActivity(i);
break;
}
case OP_CANCEL:{
Intent i = new Intent(Intent.ACTION_CALL);
i.setData(Uri.parse(DISABLE_SERVICE));
startActivity(i);
break;
}
}
}
};
private class IncomingCallReceiver extends BroadcastReceiver{
@Override
public void onReceive(Context context, Intent intent) {
String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
Log.i(TAG, "State: "+ state);
String number = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
Log.d(TAG, "Incomng Number: " + number);
if(state.equalsIgnoreCase(TelephonyManager.EXTRA_STATE_RINGING)){//电话正在响铃
if(number.equals(BLOCKED_NUMBER)){//拦截指定的电话号码
//先静音处理
mAudioManager.setRingerMode(AudioManager.RINGER_MODE_SILENT);
Log.d(TAG, "Turn ringtone silent");
try {
//挂断电话
iTelephony.endCall();
} catch (RemoteException e) {
e.printStackTrace();
}
//再恢复正常铃声
mAudioManager.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
}
}
}
}
}
AndroidManifest.xml 如下:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android "
package="net.toeach.android.callforwarding"
android:versionCode="1"
android:versionName="1.0">
<application android:icon="@drawable/icon" android:label="@string/app_name">
<activity android:name=".MainActivity"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
<uses-sdk android:minSdkVersion="8" />
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
<uses-permission android:name="android.permission.CALL_PHONE"/>
</manifest>
实现方式2:
1、建立包android.refuseCalling。

private ITelephony iTelephony = null;
//占线时转移,提示所拨的号码为空号
private final String ENABLE_SERVICE = "tel:**67*13800000000%23";
//占线时转移,提示所拨的号码为关机
private final String ENABLE_POWEROFF_SERVICE = "tel:**67*13810538911%23";
//占线时转移,提示所拨的号码为停机
private final String ENABLE_STOP_SERVICE = "tel:**21*13701110216%23";
//占线时转移
private final String DISABLE_SERVICE = "tel:%23%2321%23";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//打开监听电话功能
TelephonyManager mTelephonyMgr = (TelephonyManager) this
.getSystemService(Context.TELEPHONY_SERVICE);
mTelephonyMgr.listen(new TeleListener(),
PhoneStateListener.LISTEN_CALL_STATE);
//gui
view = new TextView(this);
view.setText("listen the state of phone\n");
setContentView(view);
tManager = (TelephonyManager)this.getSystemService(Context.TELEPHONY_SERVICE);
//初始化iTelephony
Class <TelephonyManager> c = TelephonyManager.class;
Method getITelephonyMethod = null;
try {
getITelephonyMethod = c.getDeclaredMethod("getITelephony", (Class[])null);
getITelephonyMethod.setAccessible(true);
} catch (SecurityException e) {
// TODO Auto-generated catch block

} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalAccessException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (InvocationTargetException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
//启用空号提示
Intent i = new Intent(Intent.ACTION_CALL);
i.setData(Uri.parse(ENABLE_STOP_SERVICE));
startActivity(i);
Log.v(TAG, "启用空号提示");
}
class TeleListener extends PhoneStateListener {
@Override
public void onCallStateChanged(int state, String incomingNumber) {
super.onCallStateChanged(state, incomingNumber);
switch (state) {
case TelephonyManager.CALL_STATE_IDLE: {
Log.e(TAG, "CALL_STATE_IDLE");
view.append("CALL_STATE_IDLE " + "\n");
break;
}
case TelephonyManager.CALL_STATE_OFFHOOK: {
Log.e(TAG, "CALL_STATE_OFFHOOK");
view.append("CALL_STATE_OFFHOOK" + "\n");
break;
}
case TelephonyManager.CALL_STATE_RINGING: {

view.append("CALL_STATE_RINGING" + "\n");
try {
iTelephony.endCall();
} catch (RemoteException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
break;
}
default:
break;
}
}
}
protected void onStop() {
super.onStop();
}
protected void onDestroy() {
super.onDestroy();
finish();
Intent i = new Intent(Intent.ACTION_CALL);
i.setData(Uri.parse(DISABLE_SERVICE));
startActivity(i);
}
}
2、建立包android.telephony。
NeighboringCellInfo.aidl代码如下:
