Android 从IOIO微控制器读取数据并在单击时创建新活动的应用程序

我正在创建一个应用程序，从IOIO微控制器板读取数据，并在按下按钮后将其显示在屏幕上。我有两个类，MainActivity，它有要点击的按钮，还有AugiActivity，它有所有的IOIO代码和显示信息

当我按下按钮启动新活动时，应用程序崩溃。有什么想法吗

发布你的onClick代码……和stacktrace。几个月前我遇到了类似的异常。我在这里找到了问题的解决方案：。能否确保正确构建ioio库？onclick代码位于我发布的is MainActivity.xml中。它调用MainActivity中的“call_ioio”方法。ioio图书馆很好。当我在AugiActivity中单独运行代码时，一切正常。我看到您得到了java.lang.NoClassDefFoundError。检查一些可能的解决方案。正如我在这些问题中看到的，他们使用了一些外部库，面临着一些问题。
