前言

      很久没有上博客园,更是很久没更新过随笔了。这个小小的Android应用还是去年年底开发的,过完年后一直都很忙,也比较懒,今天在整理资料的时候,觉得这个小小的应用算是学习Android开发的一个毕业作业吧,也跟大家分享一下。

      本来一直在做.net平台的开发,但是项目的需要要做一个移动终端的版本,但是这个移动终端版本并不是用原生开发的,而是基于PhoneGap框架, class="st"> 开发人员能够使用熟悉的HTML,CSS 和JavaScript 构建跨平台的移动本地应用,也可以开发原生插件配合使用。关于PhoneGap的具体介绍,大家可以google一下,这里只简短说一下优点和不足。

优点:

1、开发效率高,可以使用传统的web技术(html+css+javascript),开发人员不必学习原生开发语言;

2、成本低,一次开发维护一份代码可以打包发布多个平台,主要是Android和IOS平台;

3、可以开发原生插件,配合一些特殊功能实现,毕竟web可以做的事情还是有限的;

不足:

1、性能上和原生应用还是差一点,在IOS上明显比Android流畅,特别是运行动画和手势操作的时候,但是一般的应用型APP还是足够了;

 

     学习Android开发,纯粹是个人兴趣,在去年年底利用业余时间,自学了一下,并且现在移动应用开发这么热门,多学习一点,了解一下还是好的。对于想入门Android开发的童鞋,我也讲一下我学习的过程,供大家参考一下(仅供参考)。我没有买相关的书籍,因为有一点JAVA的基础,跳过了JAVA语言的学习,直接到http://developer.android.com/samples/index.html 上,按照里面的课程把初级和进阶的学习了,高级部分只挑选了一部分内容看了下,然后就去 一些Android论坛找一下相关的DEMO例子最多的还是有什么疑问不懂的就直接Google,初学的话基本上你遇到的问题,别人都遇到过,也会有很多的解决方法

      最后就是为什么要开发这样的一个应用,其实就是结合了生活的实际,有个朋友开了个淘宝小店,小卖家一天就10来单,但是每天点发货的时候,手工输入快递单号很麻烦,还要重复核对有没输错,所以就产生了开发一个 扫描宝 应用的想法,既可以满足不想购买市面上的扫描枪,不想手工输入条形码的盆友,又可以把之前学习的知识串联起来,重新巩固一下。

 

功能描述

  首先通过一张顺序图来描述一下该应用的功能:

  这就是该应用的主要功能,其实就是传统扫描枪的功能,将条码扫描到电脑上,只是这里利用现在智能手机的便利性和高配置,使用无线局域网,把这该功能简单化了,还省了买扫描枪的钱。现在市面上一般的扫描枪都要几十RMB,我之前在朋友那里用过一款,从淘宝上买的80大洋,有时扫描条码要几秒十几秒,还有的就是扫描不出来,郁闷到只能手工输入。假如各位童鞋身边有这样需求的朋友,也可以推荐使用以下这个APP,不用花钱。

  其他的辅助小功能,在光线不好的情况下可以开启闪光灯,在夜深人静的时候还在埋头扫描,可以关闭提示音,当然后面如果我还继续给这个应用维护或新增功能的话,就可以检查更新,继续使用新功能了。

开发思路和关键代码

  Client:

  1、摄像头扫描二维码和条形码

  这部分功能使用Google提供的ZXing开源项目,它提供二维码和条形码的扫描,就不需要自己再去详细研究具体实现了,只要知道怎么用就可以了。假如童鞋需要研究透切,可以下载源码:https://github.com/zxing/zxing ,相信对你的开发水平提高不少。这个开源项目内容很多,但是我这里要用的只是扫描二维码和条形码的功能,所以需要做一些精剪的操作,我也是主要参看以下这两篇博文,http://blog.csdn.net/ryantang03/article/details/7831826另一篇http://www.cnblogs.com/dolphin0520/p/3355728.html

  闪光灯的开启和关闭是用全局变量isLightVisiable标识,通过菜单选项控制,ZXing的CameraManager类已经公开了setTorch方法。

34         //检查更新
35         case ITEM_CHECK_UPDATE:
36             UpdateManager updateManager = new UpdateManager(CaptureActivity.this);
37             updateManager.checkUpdate();
38             break;

42             break;
43         }
44 
45         return false;
46     }

    提示音的开启和关闭时用全局变量isBeepVolue标识,通过菜单选项控制,在ZXing的CaptrueActivity类的方法handleDecode做判断。

 1 public void handleDecode(Result rawResult, Bitmap barcode, float scaleFactor) {
 2         inactivityTimer.onActivity();
 3         lastResult = rawResult;
 4         ResultHandler resultHandler = ResultHandlerFactory.makeResultHandler(
 5                 this, rawResult);
 6 
 7         if (this.isBeepVolue) {
 8             beepManager.playBeepSoundAndVibrate();
 9         }
10         handleDecodeInternally(rawResult, resultHandler, barcode);
11     }

 

  2、扫描二维码与服务端建立连接

  这部分内容主要是socket网络编程的知识,具体的连接方式这里就不介绍了,Google里面有很多,也比较简单。这里介绍一下具体流程。首先,在电脑上启动服务端,生成二维码(后面再细讲),用手机扫描二维码并Decode,在handleDecodeInternally方法判断扫描结果是不是正确的服务器地址,再与服务器做TCP连接。

 1 // Put up our own UI for how to handle the decoded contents.
 2     private void handleDecodeInternally(Result rawResult,
 3             ResultHandler resultHandler, Bitmap barcode) {
 4         // statusView1.setText();
 5         String resultStr = resultHandler.getResult().getDisplayResult();
 6         if (!this.isContentServer) {
 7             if (resultStr != null && resultStr.length() > 0) {
 8                 if (this.socketThread != null) {
 9                     this.socketThread.interrupt();
10                     this.socketThread = null;
11                 }
12                 if (this.socketThread == null) {
13                     String ip = "";
14                     int port = 8099;
15 
16                     String[] results = resultStr.split(":");
17                     if (results.length == 3) {
18                         if (results[0].equals("barcodeServer")) {
19                             if (this.isIPAdress(results[1])) {
20                                 ip = results[1];
21                                 try {
22                                     port = Integer.parseInt(results[2]);
23                                     this.socketThread = new SocketThread(
24                                             this.mHandler, new ProgressHandle(
25                                                     this), ip, port);
26                                     this.socketThread.start();
27                                 } catch (Exception en) {
28                                     showErrorDialog("请扫描正确的服务器二维码");
29                                 }
30 
31                             } else {
32                                 showErrorDialog("请扫描正确的服务器二维码");
33                             }
34                         } else {
35                             showErrorDialog("请扫描正确的服务器二维码.");
36                         }
37                     } else {
38                         showErrorDialog("请扫描正确的服务器二维码");
39                     }
40                 }
41             } else {
42                 showErrorDialog("连接服务器失败");
43             }
44         } else {
45             if (this.socketThread != null) {
            //发送条形码到服务端
46 this.socketThread.SendMessage(resultStr); 47 ClipboardInterface.setText(resultStr, this); 48 Toast.makeText(this, "已经添加到剪切板", Toast.LENGTH_LONG).show(); 49 } else { 50 showErrorDialog("已断开服务器"); 51 ((TextView) findViewById(R.id.status_server)).setText("已断开服务器"); 52 this.isContentServer = false; 53 } 54 } 55 56 new Thread() { 57 public void run() { 58 try { 59 Thread.sleep(3000); 60 Message msg = new Message(); 61 msg.obj = 1; 62 wiatHandler.sendMessage(msg); 63 } catch (InterruptedException e) { 64 e.printStackTrace(); 65 } 66 67 } 68 }.start(); 69

   建立连接后,扫描条形码发送到服务端也是在此方法中进行,其实就是客户端与服务端的相互发送和接收信息,和局域网实时聊天实例原理是一样的。

  3、检查更新

  在Android和IOS两个平台中有比较大的区别,Android比较乱有很多的应用市场,但是IOS基本上就只有AppStore,所以Android应用的话可以在应用市场上做版本更新控制,也可以在应用内部提供检查更新功能,把版本更新文件放置在自己的服务器上。本应用是使用第二种方式,下面介绍一下实现的过程。

  首先将应用安装包APK和版本控制文件XML(主要包括versionCode,appName,appUrl属性),放置到web服务器上,我这里只是简单地放在了博客园的文件管理里。在检查版本更新时先从服务器上把版本控制文件XML获取下来(Android4.2之后不允许在主线程进行HttpConnection的操作,现在网上找的相关资料大部分都比较旧的直接在主线程上下载,4.2以上的需要开启新的线程异步下载,因为这个的提示错误不是很明显,所以说明一下,稍微注意一下就可以了),拿到versionCode与本地安装的应用versionCode比较,服务器的版本号比本地的新时提示下载更新。

 1     public void checkUpdate() {

  Server:使用.net framework2.0

  1、生成服务器地址二维码

  首先获取服务器电脑IP,并随机生成端口号,拼接成服务器地址,如:192.168.1.123:8023 。同样使用ZXing的.net framew2.0版本将地址生成二维码。

   2、与客户端建立连接

  这部分其实也是socket的编程,具体也不介绍了,然后输出到光标位置,直接使用 SendKeys.Send("内容") 就可以了。

 

使用方法目前版本需要手机和服务端电脑连接在同一个无线局域网 WIFI下)

  1、下载服务器端,http://files.cnblogs.com/lijie198871/BarcodeScannerServer.rar

  2、下载Android手机客户端到本地电脑再安装到手机,http://files.cnblogs.com/lijie198871/BarcodeClient.apk

    也可以直接扫描二维码安装,或者直接在 豌豆荚 上搜索 扫描宝,就可以直接下载安装了。

  3、解压BarcodeScannerServer.rar直接运行 扫描宝Server.exe,出现二维码;

  4、使用手机运行 扫描宝 应用,扫描服务端的二维码,与服务器成功连接;

  5、将电脑光标定位到任意输入框,手机随意找一个条形码或二维码 进行扫描,就可以将内容输入到电脑上了;

 

 后续版本畅想

  1、当前版本只局限在WIFI同一个无线局域网下,应该再加上USB的连接方式、蓝牙等等;

  2、如果要按一个产品的定位去发展的话,应该要开发IOS版本,可惜苹果的开发设备太贵,买不起啊,有人资助就好了;

  3、应该加入互联网的发展方式,支持扫描云同步,现在只是简单的扫描条码到电脑上,应该还有很多适用场景,比如超市的库存清点、商品信息查看和更新云同步;快递员送货信息及时更新,一个扫描枪成本不高,但是每个快递员都带一个扫描枪,成本就非常高了, 并且手机基本上每个人都有,而且是越来越新款的智能机,装上一个扫描软件成本几乎为零,只是服务端的成本;当然现在市面上已经有的扫描比价,扫描翻译等等的功能也可以集成进去;有朝一日把传统的扫描枪淘汰掉(貌似想法有点狂妄,但是按目前互联网的发展态势,很多传统行业都在逐步被淘汰,如 拍照开片机、GPS导航等)

  4、盈利模式,还没想到,如果只是靠广告的话利润太低了,而且这样的应用别人很容易仿照复制;

  只是这样想想,后续应该不会做太大的更新了,把源码共享出来,靠各位童鞋建设了,或者放到开源社区,大家一起添砖加瓦;
