android 在线升级借助开源中国App源码

http://www.cnblogs.com/luomingui/p/3949429.html

android 在线升级借助开源中国App源码分析如下:

1: checkAppUpdate 检查是或需要升级

// 网络连接判断         if (appContext.isNetworkConnected()) {             // 检查新版本             if (appContext.isCheckUp()) {                    UpdateManager.getUpdateManager().checkAppUpdate(this, false);             }         }
