Android中自动拦截电话

1.AndroidMainFest.xml文件设置

需要的权限

<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"/><uses-permission android:name="android.permission.READ_PHONE_STATE" /><uses-permission android:name="android.permission.CALL_PHONE" /><uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/><uses-permission android:name="android.permission.CHANGE_WIFI_STATE"/><uses-permission android:name="android.permission.WAKE_LOCK"/>

注册服务：
<service android:name=".MyService"/>
2.添加AIDL文件（a、包名：com.android.internal.telephony的ITelephony类 b、包名：android.telephony的NeighboringCellInfo类）
NeighboringCellInfo类里边的内容（
package android.telephony;parcelable NeighboringCellInfo;）
3.public class MyService extends Service {

//系统提供的电话管理器private TelephonyManager telephonyManager;private MyPhoneListener myPhoneListener;
@Overridepublic IBinder onBind(Intent intent) {return null;}@Overridepublic void onCreate() {    telephonyManager = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);    myPhoneListener = new MyPhoneListener();    telephonyManager.listen(myPhoneListener, PhoneStateListener.LISTEN_CALL_STATE);    super.onCreate();}private class MyPhoneListener extends PhoneStateListener{    @Override    public void onCallStateChanged(int state, String incomingNumber) {        super.onCallStateChanged(state, incomingNumber);        switch (state){            case TelephonyManager.CALL_STATE_IDLE:                break;            case TelephonyManager.CALL_STATE_RINGING:                endCall();                Toast.makeText(getApplication(),"挂了！",Toast.LENGTH_SHORT).show();                break;            case TelephonyManager.CALL_STATE_OFFHOOK:                break;        }    }}private void endCall(){    try {        Class aClass = getClassLoader().loadClass("android.os.ServiceManager");       Method method = aClass.getDeclaredMethod("getService",String.class);       IBinder iBinder = (IBinder) method.invoke(null,TELEPHONY_SERVICE);
在使用ITelephony类之前先clean一下项目，不然可能找不到        ITelephony iTelephony = ITelephony.Stub.asInterface(iBinder);        iTelephony.endCall();    } catch (Exception e) {        e.printStackTrace();    }}@Overridepublic void onDestroy() {    telephonyManager.listen(myPhoneListener, PhoneStateListener.LISTEN_NONE);    myPhoneListener = null;    super.onDestroy();}
4.MainActivity

private Intent  callSmsSafeIntent;
在onCreate方法中{
callSmsSafeIntent = new Intent(this,MyService.class);//开启拦截服务startService(callSmsSafeIntent);
}
