No Implementation Found For Native Lcom/jp/algi/

I try everything, but I think I have ever think OK, but it still says this error: No implementation found for native Lcom/jp/algi/Corelib;.vector ([F)[F threadid=11: thread exiting

Solution 1:

Is the library really called libcom_jp_algi_Corelib.so? loadLibrary() expects the library name without the lib prefix and .so extension.

Library name is specified in Android.mk as LOCAL_MODULE. It's also without lib and extension.
