Android服务器端和客户端设计APK升级

服务器端设计： 
设计方法应该有很多，下面介绍我的一种方法：
a.首先在服务器项目下建立一个文件夹来存放APK安装文件： 
b.其次在src下建立一个资源文件，apkVersion.properties，属性定义如下写道 ：

view plaincopy to clipboardprint?
apkVersion=1 存版本号
apkSize=550kb 大小
apkPath=http://xx8080/srv/apk/Demo.apk 升级文件
apkVersion=1 存版本号
apkSize=550kb 大小
apkPath=http://xx8080/srv/apk/Demo.apk 升级文件

c.定义一个servlet来获取资源中的信息： 
定义类：UpdateApkServlet.java 

 

view plaincopy to clipboardprint?
//获取资源文件信息   
static {   
Properties ppt = new Properties();   
try {   
     ppt.load(UpdateApkServlet.class .getResourceAsStream("/apkVersion.properties"));   
     apkVersion = ppt.getProperty("apkVersion");   
     apkSize = ppt.getProperty("apkSize");   
     apkPath = ppt.getProperty("apkPath"); }   
catch (Exception e) {   
     e.printStackTrace();   
}   
}   
//获取资源文件信息
static {
Properties ppt = new Properties();
try {
     ppt.load(UpdateApkServlet.class .getResourceAsStream("/apkVersion.properties"));
     apkVersion = ppt.getProperty("apkVersion");
     apkSize = ppt.getProperty("apkSize");
     apkPath = ppt.getProperty("apkPath"); }
catch (Exception e) {
     e.printStackTrace();
}
}  

 获取资源，然后生成JSON字串返回客户端处理。 注：当客户端版本有更新，服务器端只要把APK文件拷贝到APK目录，然后更新apkVersion.properties文件中的信息就可以了，切记。 

客户端设计： 
1、 客户端首先获取服务器的版本信息（http方式获取）。 
2、 如何获取本地客户端的版本信息 如下参考代码： 

 

view plaincopy to clipboardprint?
/**  
* 得到本地应用的版本信息   
* @return  
*/  
private int getAPKVersion(){   
    //APK版本判断   
    int sdcardVersion = 0;   
    String apkFilePath="sdcard/demo.apk";  //安装包路径     
    PackageManager pm = getPackageManager();   
       
       PackageInfo info = pm.getPackageArchiveInfo(apkFilePath, PackageManager.GET_ACTIVITIES);    
       if(info != null){    
           sdcardVersion=info.versionCode;       //得到版本信息     
           Log.v(TAG, "Version="+sdcardVersion);   
       }    
       return sdcardVersion;   
}  
/**
  * 得到本地应用的版本信息 
  * @return
  */
private int getAPKVersion(){
  //APK版本判断
  int sdcardVersion = 0;
  String apkFilePath="sdcard/demo.apk";  //安装包路径 
  PackageManager pm = getPackageManager();
  
        PackageInfo info = pm.getPackageArchiveInfo(apkFilePath, PackageManager.GET_ACTIVITIES); 
        if(info != null){ 
            sdcardVersion=info.versionCode;       //得到版本信息  
            Log.v(TAG, "Version="+sdcardVersion);
        } 
        return sdcardVersion;
} 

 3、 版本比较，如果版本相同，则不执行更新，不同才进行更新操作。 这里插入客户端版本设置介绍： 客户端版本设置在AndroidManifest.xml文件中，里面有两个属性可进行版本信息设置， android:versionCode="1" 版本号 android:versionName="1.1" 版本名称 这个版本号需要和服务器端对应。 

4、 需要的权限设置 

 

view plaincopy to clipboardprint?
Sdcard访问权限： uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"
访问网络权限： uses-permission android:name="android.permission.INTERNET"
Sdcard访问权限： uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"
访问网络权限： uses-permission android:name="android.permission.INTERNET"

 5、 更新安装 当用户点击应用时执行检查更新。相关代码参考： 

 

  //弹出框提示
view plaincopy to clipboardprint?
public Handler handler = new Handler() {   
    public void handleMessage(Message msg) {   
        super.handleMessage(msg);              
        Dialog dialog = new AlertDialog.Builder(MainActivity.this).setTitle("系统更新").setMessage("发现新版本，请更新！")   
         // 设置内容   
        .setPositiveButton("确定",// 设置确定按钮   
                new DialogInterface.OnClickListener() {   
                    @Override  
                    public void onClick(DialogInterface dialog, int which) {   
                        pBar = new ProgressDialog(MainActivity.this);   
                        pBar.setTitle("正在下载");   
                        pBar.setMessage("请稍候...");   
                        pBar.setProgressStyle(ProgressDialog.STYLE_SPINNER);               
                        downFile(apkPath);   
                    }   
                }).setNegativeButton("取消", new DialogInterface.OnClickListener() {   
            public void onClick(DialogInterface dialog, int whichButton) {   
                // 点击"取消"按钮操作   
            }   
        }).create();// 创建   
    // 显示对话框       
        dialog.show();   
        }   
    };  
public Handler handler = new Handler() {
  public void handleMessage(Message msg) {
   super.handleMessage(msg);        
   Dialog dialog = new AlertDialog.Builder(MainActivity.this).setTitle("系统更新").setMessage("发现新版本，请更新！")
    // 设置内容
   .setPositiveButton("确定",// 设置确定按钮
     new DialogInterface.OnClickListener() {
      @Override
      public void onClick(DialogInterface dialog, int which) {
       pBar = new ProgressDialog(MainActivity.this);
       pBar.setTitle("正在下载");
       pBar.setMessage("请稍候...");
       pBar.setProgressStyle(ProgressDialog.STYLE_SPINNER);   
       downFile(apkPath);
      }
     }).setNegativeButton("取消", new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialog, int whichButton) {
     // 点击"取消"按钮操作
    }
   }).create();// 创建
  // 显示对话框 
   dialog.show();
         }
  };
