Hi, this looks like one of

Hi, this looks like one of the following:

- you did not build the JNI C++ source code (you need to execute "ndk-build" on the C++ source code from a Cygwin terminal)

- you did the build above, but you did not refresh the project in Eclipse after doing that

Are you sure you performed the two steps above ?

Hi Arvind, there could be

Hi Arvind,

there could be some problems with android ndk-r8c (we have seen other reports about compile issues with ndk-r8c); this looks more likely a bug in the latest NDK platform (you can probably find similar issues in Android forums);

I would recommend to install and use ndk-r8b (instead of r8c) for the moment, while waiting for some updates from the Google/Android side.
