您是否在清单中添加了新的课程NUGA_HealthCareActivity_Intro？
答案 2 :(得分：0)
你的例外说，
Caused by: java.lang.ClassNotFoundException: Didn't find class "helog.diwesh.NugaBest.NUGA_HealthCareActivity_Intro" on path: DexPathList[[zip file "/data/app/hellog.diwesh.NugaBest-2.apk"],nativeLibraryDirectories=[/data/app-lib/hellog.diwesh.NugaBest-2, /system/lib]]
这意味着您正在尝试访问类helog.diwesh.NugaBest.NUGA_HealthCareActivity_Intro，但Android的类加载器无法找到此类。
此类不存在于您的eclipse代码中以及保存在libs目录中的jar库
这个类是从库jar中引用的吗？ 尝试用最新的库替换库jar。

您的舱单中有问题，可能是这样，
检查你的包名和类名，它可能不一样..

helog.diwesh.NugaBest.NUGA_HealthCareActivity_Intro
修改
将您的lib文件夹名称更改为libs，
