尝试从Unity构建Android应用程序时出现java.lang.ClassNotFoundException

Question

我在尝试构建Android时遇到了直接崩溃。在我尝试更改捆绑包ID之前，我没有遇到任何问题，因此我们可以构建不同版本的应用。我怀疑它与插件有关（它使用playhaven等）。我做的唯一改变是改变了包ID，从那以后它在启动时立即崩溃（甚至没有进入启动画面）。我没有在android开发经验，它可能是显而易见的东西。任何帮助都会很棒，这真的让我失望了。

谢谢，

Answer 1

原来这是一个在旧的bundle_id下编译的插件。我解压缩jar，使用java类编辑器更改类中的名称和目录以匹配新的bundle id，然后更新jar文件夹以匹配这个例如（company / name / OverrideExample.Class）。然后我重新jar了新的目录和类文件，它工作。
