本项目是一个仓库管理的安卓毕业设计项目源码，已升级到 andriod studio 3.5 只是初步了实现了单机的仓库管理操作，可以对商品、客户、供应商信息进行简单的增删改查，也可以简单的进行库存管理，在实用性方面做的比较差强人意，不过可以修改一下作为自己的毕业设计。本项目包括安卓客户端源码、一个26页的毕设报告、一个开题报告，本项目是一个简单的安卓仓库管理系统模型，不要指望有多高的实际应用性。不过应付一般的本科专科水平的毕业设计完全没有问题。编译版本2.3.3编码GBK，源码有简单的注释。也可以作为安卓新手练习SQLite使用的例子。管理员默认用户名密码都是javaapk

You can cancel AsyncTask using objAsyncTask.cancel().then you just check in doInBackground, if (isCancelled()) { break; } else {        //continue... } See this Image For more Clear.
