25短信指令的广播接受者

这里创建一个短信广播接受者，并让他的优先级最大，设置他的动作为：接收短信（需要添加权限）

 <receiver android:name="com.ustc.mobilemanager.receiver.SMSReceiver" >
            <intent-filter android:priority="1000">
                <action android:name="android.provider.Telephony.SMS_RECEIVED" />
            </intent-filter>
        </receiver>

 <uses-permission android:name="android.permission.RECEIVE_SMS"/>

package com.ustc.mobilemanager.receiver;

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

public class SMSReceiver extends BroadcastReceiver {

	private static final String TAG = "SMSReceiver";

	@Override
	public void onReceive(Context context, Intent intent) {
		//写接受短信的代码

		Object[] objs = (Object[]) intent.getExtras().get("pdus");

		for (Object b : objs) {
			//具体的某一条短信
			SmsMessage sms = SmsMessage.createFromPdu((byte[]) b);
			//发送者
			String sender = sms.getOriginatingAddress();
			//短信内容
			String body = sms.getMessageBody();
			if ("#*location*#".equals(body)) {
				//得到手机的GPS
				Log.i(TAG, "得到手机的GPS");
				//把这个广播终止掉
				abortBroadcast();
			}else if("#*alarm*#".equals(body)){
				Log.i(TAG, "播放报警音乐");
				abortBroadcast();
			}else if ("#*wipedata*#".equals(body)) {
				Log.i(TAG, "远程销毁数据");
				abortBroadcast();
			}else if ("#*lockscreen*#".equals(body)) {
				Log.i(TAG, "远程锁屏");
				abortBroadcast();
			}
		}
