Error de UnsatisfiedLink: Método nativo no encontrado findLibrary devuelto null

Estoy trabajando en el proyecto android relacionado con android JNI y NDK. He loade todos los archivos .so necesarios para el proyecto. Pero sigue mostrando error que UnsatisfiedLink Error, método nativo no encontrado, findLibrary retuned null, java.lang.Runtime,

Mi imagen de registro se da a continuación

• Diferencia entre CMake y NDK en el proyecto de estudio android
• Android NDK aplicación se estrelló en ejecutar en funciones que ni siquiera llamado
• Cambiar las ubicaciones de salida de ndk-build
• No se puede encontrar android NDK constructor r9 para mac
• Creación de NDK con un archivo mk diferente para la versión / depuración

Se ve claramente desde la imagen.La biblioteca se añade, pero ¿por qué está dando error?

Hay un archivo más que está teniendo declaración de la función nativa en el archivo Utilities.java

Mi código es

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); }
