[android-beginners] Re: NoClassDefFoundError for a third party library

Hello fadden,

First of all, thank you for your help.
My classpath was effectively not correct.
Now I have a NoSuchFieldError that I will investigate.

You have three problems:

(1) You're using native code when it isn't officially supported;
(2) The class you're looking for (android.disco.Disco) wasn't found;
(3) Some native code (In JNI_OnLoad?) ignored the exception and made a
FindClass call.

If you can clean up #3, #2 will be easier to spot.  One possibility:
make sure you're passing "android/disco/Disco" into FindClass, not
"android.disco.Disco".  You're on your own for #1.
