Answer 1

有你在清單中添加新類NUGA_HealthCareActivity_Intro？

Answer 2

你說的例外，

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]]

這意味着你試圖訪問helog.diwesh.NugaBest.NUGA_HealthCareActivity_Intro類，但Android的類加載器不能找到這個類。

這個類是未出現在Eclipse代碼以及罐子庫保存在庫目錄

是這個類是從一個庫JAR簡稱？ 嘗試用最新的庫替換庫罐。

Answer 3

編輯問題

更改lib文件夾名稱以libs，

Answer 4

如果你使用Eclipse開發，到Java構建路徑/訂單出口和p首先你所有的特定圖書館。

這解決了這個問題。
