I am attempting to add a third-party library to my Android app. It utilizes a .jar file and a .so file. This is a pre-built .so file (i.e. not built specifically for the Android app) – which I know will provide me with plenty of problems down the road. I do NOT have access to the source files for the .jar or .so files!
I am attempting to dynamically load the library via a call to System.loadLibrary(“foo”);. Currently, when attempting to run the app, it crashes with the UnsatisfiedLinkError: Library foo not found. I have the .so file in both the libs/ and the libs/armeabi file in my project.
Am I chasing after a ghost here? I am trying to determine if what I’m after is even feasible. I have no native code that I’m referencing – all my function calls are to the .jar file that is, as I understand it, backed by the .so file. I have not run the Android.mk file as I’m not compiling anything – the .so file is already provided. I could really use some advice as to what direction to proceed from here.
It’s possible that the base name given to System.loadLibrary() is expanding to a file (or path) name different than that of the actual prebuilt library. Logcat should show you exactly what it is trying to load. You could also use System.load() with a full path/file name instead of System.loadLibrary() – though you really should get it working with the later.
While I think it would generate a different error message, it’s also possible that the .so is not android compatible – it must not only be for a compatible processor type and abi, but not depend on any dynamic libraries (such as a non-bionic libc) not installed on the device.
