嘿嘿。我收到了与此人相同的错误消息：“ Android NDK 应用程序无法加载库”，我正在尝试根据我的情况将这些答案转移到这里几个小时，但它不起作用。有人能帮我吗？这是这里的这个开源项目，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");
    }  
}

自由rdp.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
include $(PREBUILT_STATIC_LIBRARY)
...

您是否完全按照 github 项目中的方式复制了 Android.mk？您是否也复制了相关库？

    #
    ## libfreerdp.so
    #
    include $(CLEAR_VARS)
    LOCAL_MODULE := freerdp
    LOCAL_SRC_FILES := freerdp.c
    LOCAL_ARM_MODE := arm
    NDK_TOOLCHAIN_ROOT=/opt/android-toolchain
    LOCAL_STATIC_LIBRARIES := freerdp-utils
    LOCAL_STATIC_LIBRARIES += freerdp-locale
    LOCAL_STATIC_LIBRARIES += freerdp-crypto
    LOCAL_STATIC_LIBRARIES += freerdp-sspi
    LOCAL_STATIC_LIBRARIES += freerdp-codec
    LOCAL_STATIC_LIBRARIES += freerdp-core
    LOCAL_STATIC_LIBRARIES += freerdp-cache
    LOCAL_STATIC_LIBRARIES += freerdp-gdi
    LOCAL_STATIC_LIBRARIES += freerdp-rail
    LOCAL_STATIC_LIBRARIES += freerdp-channels
    LOCAL_STATIC_LIBRARIES += rdpsnd_alsa
    LOCAL_STATIC_LIBRARIES += cliprdr
    LOCAL_STATIC_LIBRARIES += rdpsnd
    LOCAL_STATIC_LIBRARIES += freerdp_android

在 Java 方面，您似乎也应该按适当的顺序加载其他库：

static {
    System.loadLibrary("freerdp-utils");
    System.loadLibrary("freerdp-codec");
    System.loadLibrary("freerdp-gdi");
    System.loadLibrary("freerdp-core");
    System.loadLibrary("freerdp-rail");
    System.loadLibrary("freerdp-chche");
    System.loadLibrary("freerdp-crypto");
    System.loadLibrary("freerdp-sspi");
    System.loadLibrary("freerdp-channels");
    System.loadLibrary("rdpsnd_alsa");
    System.loadLibrary("cliprdr");
    System.loadLibrary("rdpsnd");
    System.loadLibrary("freerdp_android");
    System.loadLibrary("freerdp");
}
