创建自定义键盘时发生Java.lang.classnotfoundException

我想在android中创建一个自定义键盘。为此，我遵循了以下教程：-

本教程没有活动类，只有服务类。当我运行代码时，它会给我classnotfound异常，如下所示：-

我搜索了所有地方，但没有找到解决方案。一个解决方案是检查类的名称（simpleme）和mainfest声明名称（.simpleme）是否相同。请帮助我解决这个问题。我没有找到解决方案

查看

simpleme

类的顶部，包声明只列出

kb

，而查看类加载器试图加载的内容应该是

com.example.kb

。同样地，你确定你的

simpleme

类在正确的包中吗？哇，你真是天才。我刚刚删除了作为kb的默认包。并创建了一个名为“com.example.kb”的新类。它工作正常。感谢lot查看
