ndk-samples: Execution failed for task ':app:externalNativeBuildDebug'

Hi, I’m learning to use NDK,

1. I’ve created a new project
2. check the c++ support
3. use c++ 11 option The generated project run fine and show the “hello from c++”. Then I tried to change the code at native-lib.cpp from sample code of bitmap plasma:

#include <jni.h>
#include <string>
#include <android/bitmap.h>
#include <android/log.h>
#define  LOG_TAG    "cardscanner"
#define  LOGE(...)  __android_log_print(ANDROID_LOG_ERROR,LOG_TAG,__VA_ARGS__)

extern "C"
jstring
Java_com_aprisma_cardscanner_cardscanner_MainActivity_stringFromJNI( JNIEnv *env,  jobject /* this */, jobject bitmap) {
    AndroidBitmapInfo  info;
    void*              pixels;
    int                ret;
    static int         init;
    if ((ret = AndroidBitmap_getInfo(env, bitmap, &info)) < 0) {
        LOGE("AndroidBitmap_getInfo() failed ! error=%d", ret);
        return NULL;
    }
    if (info.format != ANDROID_BITMAP_FORMAT_RGB_565) {
        LOGE("Bitmap format is not RGB_565 !");
        return NULL;
    }
    if ((ret = AndroidBitmap_lockPixels(env, bitmap, &pixels)) < 0) {
        LOGE("AndroidBitmap_lockPixels() failed ! error=%d", ret);
    }
    std::string hello = "Hello sjfosfosjf";
    return env->NewStringUTF(hello.c_str());
}

and change MainActivity.java :

package com.aprisma.cardscanner.cardscanner;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.TextView;
import android.graphics.Bitmap;

public class MainActivity extends AppCompatActivity {
    static {System.loadLibrary("native-lib");}

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        TextView tv = (TextView) findViewById(R.id.sample_text);
        tv.setText(stringFromJNI(null));
    }
    public native String stringFromJNI(Bitmap  bitmap);
}

Got error:
