I am working on android project related to android JNI and NDK . I have loade all the .so files required for the project.But it is still showing error that UnsatisfiedLink Error, Native method not found, findLibrary retuned null, java.lang.Runtime,
My log image is given below
It is clearly seen from the image.Library is added but why it is giving error?
There is one more file which is having declaration of native function in Utilities.java file
My code is
package me.frankly.utils;
import java.nio.ByteBuffer;
import android.util.Log;
public class Utilities {
static
{
try
{
System.loadLibrary("videocompression");
}
catch(Exception e)
{
Log.d("Exception",e.toString());
}
}
public native static int convertVideoFrame(ByteBuffer src, ByteBuffer dest,
int destFormat, int width, int height, int padding, int swap);
}
