try { String pkName = context.getPackageName(); versionCode = context.getPackageManager().getPackageInfo(pkName, 0).versionCode; } catch (PackageManager.NameNotFoundException e) { e.printStackTrace(); } return versionCode; }}getAppVersion方法中的联网操作使用的http请求框架不同可能有所不同。单应该所有的http请求回调方法都有一个成功的回调和一个失败的回调。本人使用的自己封装的okhttp，方法类似2.用到的布局
