Android Cordova App crashes with ClassNotFoundException?

I have a problem with an android app. The following is the error message I get:

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]]


I tried the following things:


  • Delete R.java

  • Clean project

  • Check all dependencies under project preferences -> order and export

  • Uncheck "Is Library" under Tab "Android" under Project Preferences

  • Restart Eclipse

  • Try another workspace



Nothing works. Anyone knows how this error comes and how I can resolve it?

The Manifest:

Answer

rename package path (in Eclipse, not in Manifest) of WIEDEMANN.java into wiedemann.app > de.wiedemann.mobile (as you can see in gen folder correct package name). Please, change symbols to lower case. Use F2 hot key in order to rename;)
