短信拦截的二种处理方式

最近项目中要做的一个拦截某一个特定号码发来的短信的小功能，遇到到小问题（不得不说有些软件好过分啊），记录一下。

1：拦截系统发送的短信广播
我们知道，系统在收到短信的时候，会发送一个短信广播，而广播的种类又分为有序广播和无序广播，而这个短信广播就是有序广播，我们在收到这个广播之后，可以abort掉，那么优先级在你后面的receiver就会接收不到这个广播了，然后麻烦就来了，有些短信软件比如说youni，360等等就会abort掉后让你接受不到这个广播了，还有一些定制android的rom根本不会让你接收到这个广播，也就是说通过广播来做拦截是有前提的。

package com.android.shop.sms;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.SmsMessage;
import android.util.Log;

import com.android.shop.Constants;
/**
 * 短信拦截器,拦截电信短信平台数据
 * @author cg

 */
public class SmsReceiver extends BroadcastReceiver {
	public static final String TAG = "SmsReceiver";
	public static final String SMS_RECEIVED_ACTION = "android.provider.Telephony.SMS_RECEIVED";
	public static final String SENDER_ADDRESS = "106903007090999";//sp短信发送地址,拦截注册时服务商发出短信
	
	@Override
	public void onReceive(Context context, Intent intent) {
		if (intent.getAction().equals(SMS_RECEIVED_ACTION)){
			SmsMessage[] messages = getMessagesFromIntent(intent);
			for (SmsMessage message : messages){
				if(message.getOriginatingAddress().indexOf(SENDER_ADDRESS)!=-1){
					Log.d(TAG, message.getMessageBody());
					Intent it = new Intent();
					it.setAction(Constants.CAN_BIND_PHONE_ACTION);
					String key = message.getMessageBody();
					it.putExtra("key", key);
					context.sendBroadcast(it);
					abortBroadcast();
				}
			}
		}
	}
	
	public final SmsMessage[] getMessagesFromIntent(Intent intent){
		Object[] messages = (Object[]) intent.getSerializableExtra("pdus");
		byte[][] pduObjs = new byte[messages.length][];
		for (int i = 0; i < messages.length; i++){
        	pduObjs[i] = (byte[]) messages[i];
        }
		byte[][] pdus = new byte[pduObjs.length][];
		int pduCount = pdus.length;
		SmsMessage[] msgs = new SmsMessage[pduCount];
		for (int i = 0; i < pduCount; i++){
        	pdus[i] = pduObjs[i];
        	msgs[i] = SmsMessage.createFromPdu(pdus[i]);
        }
        return msgs;
	}
	

}

2:通过ContentObserver监听短信数据库

private ContentObserver smsContentObserver =  new ContentObserver(new Handler()) {
		@Override
		public void onChange(boolean selfChange) {
			super.onChange(true);
			/*Cursor cursor = resolver.query(
					Uri.parse(SMS_INBOX_URI),
					new String[] { "_id", "address", "thread_id", "date",
							"protocol", "type", "body", "read" },
					" address=? and read=?", new String[] {SENDER_ADDRESS, "0"},
					"date desc");*/
			[color=red]//注释掉的是查未读状态的，但如果你的手机安装了第三放的短信软件时，他们有可能把状态改变了，你就查询不到数据[/color]
			Cursor cursor = resolver.query(
					Uri.parse(SMS_INBOX_URI),
					new String[] { "_id", "address", "thread_id", "date",
							"protocol", "type", "body", "read" },
					" address=?", new String[] {SENDER_ADDRESS},
					"date desc");
			
			while(cursor.moveToNext()){
				String address = cursor.getString(cursor.getColumnIndex("address"));
				String body = cursor.getString(cursor.getColumnIndex("body"));
				String id = cursor.getString(cursor.getColumnIndex("_id"));
				resolver.delete(Uri.parse("content://sms/"+id), null, null);
				Log.d("短信平台发来的短信---", address+":::::"+body);
				
				break;
			}
		}
	}; 

	@Override
    protected void onResume() {
    	super.onResume();
	ContentResolver resolver = getContentResolver()；
    	resolver.registerContentObserver(Uri.parse(SMS_URI), true,smsContentObserver);
    }

public static final String SMS_URI = "content://sms/";//1.6下的系统
public static final String SMS_URI = "content://mms-sms/";[color=red]//1.6+的系统，要不然有些rom会onChange执行不了，也就是监听不了[/color]
public static final String SMS_INBOX_URI = "content://sms";
