Android SDK 应用加载库失败

Question

嘿嘿。我收到了与这个人相同的错误消息:“Android NDK app failed to load library”几个小时以来，我一直在尝试根据我的情况将这些答案转移到这里，但它不起作用。有人能帮我吗？这是这里的开源项目，我想尝试让它在我的模拟器上运行。 https://github.com/itskewpie/FreeRDP-android

FreeRDPActivity.java

package net.itskewpie.freerdp;

import android.app.Activity;
import android.os.Bundle;

public class FreeRDPActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    } 
    static {       
        System.loadLibrary("freerdp");
    }  
}

freerdp.c

#include <jni.h>
#include <stdio.h>
#include <freerdp/freerdp.h>

jstring Java_net_itskewpie_freerdp_FreeRDPActivity_test(JNIEnv* env, jobject thiz )
{
    android_main();      
    return (*env)->NewStringUTF(env, "HELLO");
}

安卓.mk

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)

MY_LIBS_PATH=freerdp-1.0-nevo/libs/armeabi-v7a
LOCAL_MODULE    := freerdp-utils
LOCAL_SRC_FILES := $(MY_LIBS_PATH)/libfreerdp-utils.a
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/freerdp-1.0-nevo/include
