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" package="com.javen.sms" android:versionCode="1" android:versionName="1.0" > <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="21" /> <uses-permission android:name="android.permission.SEND_SMS" /> <uses-permission android:name="android.permission.RECEIVE_SMS" /> <!-- <uses-permission android:name="android.permission.BROADCAST_SMS" /> <uses-permission android:name="android.permission.READ_SMS" /> <uses-permission android:name="android.permission.WRITE_SMS" /> --> <application android:allowBackup="true" android:icon="@drawable/ic_launcher" 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> <receiver android:name="com.javen.sms.receiver.SmsReceiver" android:exported="true" android:permission="android.permission.BROADCAST_SMS"> <intent-filter android:priority="2147483647" > <action android:name="android.provider.Telephony.SMS_RECEIVED" /> <action android:name="android.provider.Telephony.SMS_DELIVER" /> <category android:name="android.intent.category.DEFAULT" /> </intent-filter> </receiver> <service android:name="com.javen.service.SmsService"></service> </application> </manifest>

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。。。。。
