How do I set a relative path for an .SO file?

Question

This is my error:

06-29 16:52:37.729 24144-24144/com.my.app E/AndroidRuntime﹕ FATAL EXCEPTION: main Process: com.my.app, PID: 24144 java.lang.UnsatisfiedLinkError: dlopen failed: could not load library "build/obj/local/armeabi/libavformat.so" needed by "libFFmpegWrapper.so"; caused by library "build/obj/local/armeabi/libavformat.so" not found

build/obj/local/armeabi/libavformat.so looks wrong to me. The code worked with an earlier build of ffmpeg - so I suspect it's something to do with the way I build ffmpeg.

The libavformat.so file is in the APK where I'd expect it to be.

This is my build script for ffmpeg:

#!/bin/bash

NDK=/Users/eran/Downloads/android-ndk-r10e
PREBUILT=$NDK/toolchains/arm-linux-androideabi-4.9/prebuilt/darwin-x86_64
PLATFORM=$NDK/platforms/android-12/arch-arm

Solved by loading all required libraries rather than letting the system try and find them itself.

System.loadLibrary("x264");
System.loadLibrary("avutil");
System.loadLibrary("avcodec");
System.loadLibrary("avformat");
System.loadLibrary("swresample");
System.loadLibrary("swscale");
System.loadLibrary("FFmpegWrapper");
