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; /** * 演示如何设置呼叫转移,拦截电话(拦截后提示为空号)的例子 * @author Tony from ToEach. * @email [email protected] */ 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:
实现方式2:
1、建立包android.refuseCalling。
refuseCalling.java代码如下:
package android.refuseCalling; import android.app.Activity; import android.net.Uri; import android.os.Bundle; import java.lang.reflect.InvocationTargetException; import java.lang.reflect.Method; import android.content.Context; import android.content.Intent; import android.os.RemoteException; import android.telephony.PhoneStateListener; import android.telephony.TelephonyManager; import android.util.Log; import android.widget.TextView; import com.android.internal.telephony.ITelephony; public class refuseCalling extends Activity { private static final String TAG = "Telephony"; private TextView view = null; private TelephonyManager tManager = null; 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 Classc = TelephonyManager.class; Method getITelephonyMethod = null; try { getITelephonyMethod = c.getDeclaredMethod("getITelephony", (Class[])null); getITelephonyMethod.setAccessible(true); } catch (SecurityException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (NoSuchMethodException e) { // TODO Auto-generated catch block e.printStackTrace(); } try { iTelephony = (ITelephony) getITelephonyMethod.invoke(tManager, (Object[])null); } 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: { Log.e(TAG, "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:
package android.telephony;
3、建立包 com.android.internal.telephony。
ITelephony.aidl代码如下:
