JNI - System.LoadLibrary() finds wrong dependent dll
I am linking a native C++ library into my Java application using JNI. I loaded my library using System.loadLibrary() and everything appears to be working.

JNI Header file generating class
Hi, I'm currently using the JNI to generate C headers for native methods being used in a Java class ABC. However, I'd like to use these methods elsewhere, in another class XYZ, so hence I made a class called cLib which basically just had the prototypes of the native methods, and which when generated gave me the header file for the meth...

Preventing functions from being stripped from a static library when linked into a shared library?
I have a static library, Foo, that is used by a shared library, Bar. Bar is the native shared library loaded by my Android app. Foo contains JNI functions that are only called by Java code and not by any C++ code in Bar. Because of this, those JNI functions get stripped out of the static library (Foo) when the shared library (Bar) is bui...

JNI - UnsatisfiedLinkError - loadLibrary always fails
I am attempting to get a simple JNI example working, but no matter what I do, I cannot get it to work using the loadLibrary command. It works perfectly if I specify the absolute path of the .so file and use System.load instead of System.loadLibrary.
