问题 I successfully processed my jar and apk. Then, want to verify if is it truly hard to reverse engineer or truly did the obfuscation. I am thinking to try to reverse engineer it by myself to see what I did. But don't know how to do it. 回答1: For manual reverse engineering, you can try dex2jar and then Java Decompiler. 回答2: I assume you have a set of tests (unit/functionality). Run them against the obfuscated jar file. They should pass as if you had the original program. 来源： https://stackoverflow

And android packages will have some sort of XML file that will mention the version information. In PHP

六年来，我为多家公司编写过各种应用程序。你编写代码或处理代码库的文化和方式会随着你的经验而不断变化。你的代码质量应该随着经验的增加而提高，否则就需要反思了。选择正确的架构如果你是从头开始开发应用程序，那么就会有许多优势。其中之一就是选择正确的体系结构。通常，我们喜欢将所有内容都写在同一个activity文件中，因为这样做很容易。但是，当你的代码量增多时，这就会成问题。你的代码库会变得十分庞大，每个文件包含的代码行数也会非常庞大。考虑到代码的性能和维护，在早期阶段选择正确的体系结构，才是明智的做法。 MVC、MVP、MVVM和MVI等许多体系结构可帮助 Android 开发人员轻松维护、测试和开发新功能。上图说明了在设计完应用程序后，所有模块应如何相互交互。尽管这完全取决于你的组织，但你也有可能会有机会选择适合应用程序的体系结构。但是，强烈建议你选择适合需求的特定体系结构。关于哪种架构最好这个话题也是众说纷纭。根据开发人员指南： “没有任何一种方法能够编写出适用于每种情况的最佳应用程序。话虽如此，对于大多数情况和工作流来说，这种推荐的体系结构都是一个很好的起点。” 善加利用Android Studio Android Studio 提供了最快的工具，可以为每种类型的 Android 设备构建应用程序。不幸的是，我们仅探索了该IDE的一小部分。Android
