直接上代码了，此处不难理解。有什么问题可以留言。

从服务器获取xml解析并进行比对版本号

class CheckVersionTask implements Runnable{ 
        public void run() {  
            try {  
                //从资源文件获取服务器 地址   
                String update_url = ServerBiz.getServer(HomeActivity.this, "update_url");
                //包装成url的对象   
                URL url = new URL(update_url);  
                HttpURLConnection conn =  (HttpURLConnection) url.openConnection();   (此处报错，输出conn.getResponseCode()看看！)
                conn.setConnectTimeout(5000);  
                InputStream is =conn.getInputStream();   
                
                //获得更新文件的信息
                UpdateInfo info =  DownLoadManager.getUpdateInfo(is); 
                if(info.getVersion().equals(getVersionName())){  
                    Log.i("liyongjun","版本号相同无需升级");  
                }else{  
                    Log.i("liyongjun","版本号不同 ,提示用户升级 ");  
                    Intent intent = new Intent("com.ccfrom.cclive.ACTION.ApkUpdate");
                    intent.putExtra("updatemsg", info.getDescription());
                    intent.putExtra("filepath",info.getUrl());
                    sendBroadcast(intent);
                }  
            } catch (Exception e) {  
                // 待处理   
                Message msg = new Message();  
                msg.what = GET_UNDATAINFO_ERROR;  
                handler.sendMessage(msg);  
                e.printStackTrace();  
            }   
        }  
    }

获取package的版本号，配置在manifest中的

private String getVersionName() throws Exception{  
        //获取packagemanager的实例   
        PackageManager packageManager = getPackageManager();  
        //getPackageName()是你当前类的包名，0代表是获取版本信息  
        PackageInfo packInfo = packageManager.getPackageInfo(getPackageName(), 0);  
        return packInfo.versionName;   
    }

注册此接收器：

class ApkUpdateReciver extends BroadcastReceiver {
        public void onReceive(Context paramContext, Intent paramIntent) {
            String str1 = paramIntent.getAction();
            if (str1.equals("com.ccfrom.cclive.ACTION.ApkUpdate")) {
                String updatemsg = paramIntent.getStringExtra("updatemsg");
                String filepath = paramIntent.getStringExtra("filepath");
                HomeActivity.this.createUpdateDialog(updatemsg, filepath).show();
                HomeActivity.this.removeStickyBroadcast(paramIntent);
            }
        }
    }

创建提示框，是否更新版本

public AlertDialog createUpdateDialog(String updatemsg, final String filepath) {
         AlertDialog.Builder builer = new Builder(this) ;  
            builer.setTitle("版本升级"); 
            builer.setMessage(updatemsg); 
            builer.setPositiveButton("确定", new OnClickListener() { 
                public void onClick(DialogInterface dialog, int which) { 
                        downLoadApk(filepath); 
                    }    
                }); 
                builer.setNegativeButton("取消", new OnClickListener() { 
                    public void onClick(DialogInterface dialog, int which) { 
                        Log.e("HomeActivity", "Enter Main..");
                    } 
                }); 
               
        return builer.create();
    }

从服务器中下载apk

 protected void downLoadApk(final String filePath) { 
        pd = new  ProgressDialog(this); 
        pd.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL); 
        pd.setMessage("正在下载更新"); 
        pd.show(); 
        new Thread(){ 
            @Override 
            public void run() { 
                try { 
                    File file = DownLoadManager.getFileFromServer(filePath, pd); 
                    sleep(3000);                     
                    installApk(file); 
                    pd.dismiss(); //结束掉进度条对话框 
                } catch (Exception e) { 
                    e.printStackTrace(); 
                    Message msg = new Message(); 
                    msg.what = DOWN_ERROR; 
                    handler.sendMessage(msg); 
                } 
            }}.start(); 
    }

安装已下载的apk，并结束当前应用

 protected void installApk(File file) { 
        Intent intent = new Intent(); 
        //执行动作 
        intent.setAction(Intent.ACTION_VIEW); 
        //执行的数据类型 
        intent.setDataAndType(Uri.fromFile(file), "application/vnd.android.package-archive"); 
        startActivity(intent); 
    }

以下贴上前面需要使用到的类方法：

ServerBiz.java

private static ServerInfo parserServerXml(String paramString) {
        ServerInfo mServerInfo = null;
        if (paramString != null) {
            mServerInfo = new ServerInfo();
            try {
                DocumentBuilderFactory domfac = DocumentBuilderFactory
                        .newInstance();
                DocumentBuilder dombuilder = domfac.newDocumentBuilder();
                Document doc;
                Element root;
                NodeList maps;
                URL url = new URL(paramString);
                doc = dombuilder.parse(url.openStream());
                root = doc.getDocumentElement();
                maps = root.getChildNodes();

                for (Node node = maps.item(1).getFirstChild(); node != null; node = node
                        .getNextSibling()) {
                    if (node.getNodeType() == Node.ELEMENT_NODE) {
                        Log.e("liyongjun","name = " + node.getNodeName());
                        if (node.getNodeName().equals("hosturl"))
                            mServerInfo.hosturl = node.getTextContent();
                        else if (node.getNodeName().equals("liveurl"))
                            mServerInfo.liveurl = node.getTextContent();
                        else if (node.getNodeName().equals("mv_url"))
                            mServerInfo.mv_url = node.getTextContent();
                        else if (node.getNodeName().equals("news_url"))
                            mServerInfo.news_url = node.getTextContent();
                        else if (node.getNodeName().equals("playurl"))
                            mServerInfo.playurl = node.getTextContent();
                        else if (node.getNodeName().equals("tvback_url"))
                            mServerInfo.tvback_url = node.getTextContent();
                        else if (node.getNodeName().equals("tvepg_url"))
                            mServerInfo.tvepg_url = node.getTextContent();
                        else if (node.getNodeName().equals("update_url"))
                            mServerInfo.update_url = node.getTextContent();
                       
                    }
                }

            } catch (Exception e) {

                e.printStackTrace();
            }

        }
        return mServerInfo;
    }

   private static void saveServerInfo(Context paramContext,
            ServerInfo paramServerInfo) {
        SharedPreferences.Editor localEditor = paramContext
                .getSharedPreferences("server_preferences",
                        paramContext.MODE_PRIVATE).edit();
        localEditor.putString("hosturl", paramServerInfo.hosturl);
        localEditor.putString("liveurl", paramServerInfo.liveurl);
        localEditor.putString("mv_url", paramServerInfo.mv_url);
        localEditor.putString("news_url", paramServerInfo.news_url);
        localEditor.putString("playurl", paramServerInfo.playurl);
        localEditor.putString("tvback_url", paramServerInfo.tvback_url);
        localEditor.putString("tvepg_url", paramServerInfo.tvepg_url);
        localEditor.putString("update_url", paramServerInfo.update_url);
        localEditor.commit();
    }

    public static String getServer(Context paramContext, String paramString) {
        return paramContext.getSharedPreferences("server_preferences",
                paramContext.MODE_PRIVATE).getString(paramString, null);
    }

UpdateInfo.java

    private String version; 
    private String url; 
    private String description;
   
    public String getVersion() {
        return version;
    }
    public void setVersion(String version) {
        this.version = version;
    }
    public String getUrl() {
        return url;
    }
    public void setUrl(String url) {
        this.url = url;
    }
    public String getDescription() {
        return description;
    }
    public void setDescription(String description) {
        this.description = description;
    }

update.xml 此文件放于服务器指定位置，用来比较当前版本的版本号

<?xml version="1.0" encoding="utf-8"?>
<info> 
    <version>2.0</version> 
    <url>http://ccfrom.qtcms.cn/files/CcLive.apk</url> 
    <description>检测到最新版本，请及时更新！</description>
