Android Cordova 应用程序因 ClassNotFoundException 而崩溃？

Question

我的 android 应用程序有问题。以下是我得到的错误信息：

11-06 18:15:02.606: E/AndroidRuntime(2424): java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{de.wiedemann.mobile/de.wiedemann.mobile.WIEDEMANN}: java.lang.ClassNotFoundException: Didn't find class "de.wiedemann.mobile.WIEDEMANN" on path: DexPathList[[zip file "/data/app/de.wiedemann.mobile-1/base.apk"],nativeLibraryDirectories=[/vendor/lib, /system/lib]]

我尝试了以下操作：

删除R.java
清理项目
检查项目首选项下的所有依赖项 -> 顺序和导出
取消选中项目首选项下 "Android" 选项卡下的 "Is Library"
重新启动 Eclipse
尝试另一个工作区

没有任何效果。有谁知道这个错误是怎么来的，我该如何解决？

编辑：

只需将 activity 标签中的 android:name 重命名为 wiedemann.app.WIEDEMANN。看完截图后 http://imgur.com/oYTN4ZN

我想到我之前提出了错误的答案。

或者将其粘贴到 manifest.xml:

<?xml version='1.0' encoding='utf-8'?>
<manifest android:hardwareAccelerated="true" android:versionCode="16" android:versionName="0.0.1" android:windowSoftInputMode="adjustPan" package="de.wiedemann.mobile" xmlns:android="http://schemas.android.com/apk/res/android">

            </intent-filter>

Answer 2

将 WIEDEMANN.java 的包路径（在 Eclipse 中，而不是在 Manifest 中）重命名为 wiedemann.app > de.wiedemann.mobile（如您在 gen 文件夹中看到的正确包名称） .请将符号更改为小写。使用 F2 热键重命名;)
