Hi all, I've already spend a lot hours and really come to no solution. Any help or hints would be great.
What I'm doing: 1. use a custom "build.xml" to add a package as asset to my app 2. on the app start read from asset and write the jar-file to private app-directory (/data/data/MY_PACKAGE/app_dex/JAR_FILE) 3. then using DexClassLoader.loadClass and an interface of this class I call a method The whole thing works on Android 2.1 and has worked some months ago on Jelly Bean too. If I run the app from eclipse it works as well. But if I do "ant release" and install the ...release.apk to my device (4.2.2) I get: java.lang.ClassNotFoundException: Didn't find class "MY_CLASS" on path: /data/data/MY_PACKAGE/app_dex/JAR_FILE I've already checked, the JAR_FILE exists, it's readable. I've also extracted the asset-file and done "dexdump" - the class is there, the name is correct. And as I say, this works on Android 2.1 Really no idea... it's on ADT 17?
