java.lang.UnsatisfiedLinkError: Couldn't load from loader findLibrary returned null

I use NDK in eclipse.

This is my NativeLib in java: 

public class NativeLib {

public native String enCode(String src);

static {
    System.loadLibrary("HelloWorld");
}

public native String deCode(String src);
}

This is C source:

#include <string.h>
#include <jni.h>
#include <stdio.h>

jstring Java_com_example_helloworld_NativeLib_enCode(JNIEnv* env,
    jobject thiz, jstring src) {
...
return (*env)->NewStringUTF(env, result);
}

jstring Java_com_example_helloworld_NativeLib_deCode(JNIEnv* env, jobject thiz,
    jstring src) {
...
return (*env)->NewStringUTF(env, result);
}

My project run normally in android 4.2 but in android 4.3(Tablet ASUS K012) It get error like below

java.lang.UnsatisfiedLinkError: Couldn't load HelloWorld from loader dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/com.example.helloworld-2.apk"],nativeLibraryDirectories=[/data/app-lib/com.example.helloworld-2, /vendor/lib, /system/lib, /system/lib/arm]]]: findLibrary returned null

Can anyone help me?

It could be because you are not compiling your native code for all platforms. ASUS K012 is running Intel processor and that might be the reason. Add a file called application.mk within your JNI folder and the following parameter APP_ABI := all

This compiles the native portion for all platforms.
