暗扣，強烈譴責這種侵害用戶利益的行為。。。
下面給大家介紹Android暗扣原理....... Android4.4以下的系統玩游戲就要小心了哈
暗扣方式之一：短信訂購，即監聽--------攔截------------處理短信。
暗扣方式之二：模擬人為操作（又叫模擬流量），通過后台程序代碼模擬人的點擊行為，暗自給用戶訂購業務，由運營商收取你的費用，當然這其中也需要涉及監聽/攔截/處理短信。使用這種方式的原理無非是Http處理網頁，還涉及接入點切換問題，這里就不詳細講解。
回歸正題：有的時候，我們的手機程序需要監聽手機短信，當滿足條件A時，不處理；當滿足條件B時，將其設置為已讀；當滿足條件C時，將短信刪除。
注：Android 4.4以及以后可能由用戶來控制程序的權限，如果用戶關閉這個程序的權限，意味着你無法監聽短信/操作短信內容
目前也有如小米系統在安裝時，讓用戶來控制權限；360來監聽優先攔截短信等等（關於誰先安裝誰有優先權，動態注冊比靜態注冊優先級別高等問題，在這些情況這里就不講了）。。。
Android 實現監聽短信(同時監聽廣播和數據庫)代碼如下：
- 攔截廣播
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, "接收短信執行了.....", Toast.LENGTH_LONG).show(); Log.e("SMSReceiver, isOrderedBroadcast()=", isOrderedBroadcast()+""); Log.e("SmsReceiver onReceive...", "接收短信執行了......"); String action = intent.getAction(); if (SMS_RECEIVED_ACTION.equals(action) || SMS_DELIVER_ACTION.equals(action)) { Toast.makeText(context, "開始接收短信.....", Toast.LENGTH_LONG).show(); Log.e("SmsReceiver onReceive...", "開始接收短信....."); 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();// 得到短信內容 String sender = message.getOriginatingAddress();// 得到發信息的號碼 if (content.contains(InterceptKeyKeeper.getInterceptKey(mContext))) { Toast.makeText(mContext, "內容為："+content, Toast.LENGTH_LONG).show(); //setResultData(null); this.abortBroadcast();// 中止 }else if (sender.equals("10010") || sender.equals("10086")) { Toast.makeText(mContext, "內容為："+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 +" "); } } } } } }
- 開啟一個服務開監聽數據庫
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 * 開啟一個服務開監聽數據庫 */ public class SmsService extends Service { private SmsObserver mObserver; @Override public IBinder onBind(Intent intent) { return null; } @Override public void onCreate() { Toast.makeText(this, "SmsService 服務器啟動了....", Toast.LENGTH_LONG).show(); // 在這里啟動 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()); } }
- 數據庫觀察者
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 * 數據庫觀察者 */ 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 短信有改變"); 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); } // 根據你的攔截策略，判斷是否不對短信進行操作;將短信設置為已讀;將短信刪除 // TODO System.out.println("獲取的短信內容為："+_smsInfo.toString()); Log.i("SmsObserver ...", "獲取的短信內容為："+_smsInfo.toString()); Message msg = smsHandler.obtainMessage(); _smsInfo.action = 2;// 0不對短信進行操作;1將短信設置為已讀;2將短信刪除 msg.obj = _smsInfo; smsHandler.sendMessage(msg); } } if (mCursor != null) { mCursor.close(); mCursor = null; } } }
- 短信處理類
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 * * 短信的處理 * */ 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 數據結構 主要用於短信攔截
package com.javen.service; /** * 主要用於短信攔截 * * @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代表設置為已讀，2表示刪除短信 @Override public String toString() { return "SmsInfo [_id=" + _id + ", thread_id=" + thread_id + ", smsAddress=" + smsAddress + ", smsBody=" + smsBody + ", read=" + read + ", action=" + action + "]"; } }
- 需要的權限以及配置信息
<?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>

測試在MainActivity 中啟動SmsService 發送短信到10086 或者10010即可測試
intentService = new Intent(this, SmsService.class); startService(intentService); Toast.makeText(this, "啟動service中.....", 1).show();
以上就是Android 4.4以下暗扣原理。 Android 4.4以上如何實現大家可以在此博客中討論交流。。。。。
