源码介绍
common.java中 有apk下载地址以及服务器的地址（需做更改） ，如下
public static final String SERVER_IP="http://192.168.1.105/";
public static final String SERVER_ADDRESS=SERVER_IP "try_downloadFile_progress_server/index.php";//软件更新包地址
public static final String UPDATESOFTADDRESS=SERVER_IP "try_downloadFile_progress_server/update_pakage/baidu.apk";//软件更新包地址
