参考文章:http://thesoftwarerogue.blogspot.com/2010/05/porting-of-libcurl-to-android-os-using.html 及提供的 NDK project files
材料找了挺久的结果发现被墙了..对此表示无语....不发表意见...
以下方法是通过curl库进行访问网络的...这里提供下载地址:http://curl.haxx.se/download.html
一、在NDK目录下建立生成库的文件结构。
在apps目录下创建目录 \apps\curljni\project\jni\curl
二、配置下载的curl-7.29.0.tar.gz
将curl官方文档解压得到的lib、include、src文件夹整个复制到\apps\curljni\project\jni\curl目录下
用以下内容来覆盖复制过来的文件夹lib下的curl_config.h //配置curl用到的功能,从上面提供 NDK project files下载地址里面有

三、编写NDK文件调用curl访问网络
在\apps\curljni\project\jni\目录下建立文件curljni.c
// 调试 LOGI(" %d", len); #include<android/log.h> #define LOG_TAG "debug" #define LOGI(fmt, args...) __android_log_print(ANDROID_LOG_INFO, LOG_TAG, fmt, ##args) #define LOGD(fmt, args...) __android_log_print(ANDROID_LOG_DEBUG, LOG_TAG, fmt, ##args) #define LOGE(fmt, args...) __android_log_print(ANDROID_LOG_ERROR, LOG_TAG, fmt, ##args) #include <jni.h> #include <string.h> #include "curl/curl.h" //回调函数中自定义参数的类型 struct FtpFile { const char *filename; FILE *stream; }; //回调函数获取数据 static size_t my_fwrite(void *buffer, size_t size, size_t nmemb, void *stream) { LOGI("buffersize %d",size*nmemb); struct FtpFile *out=(struct FtpFile *)stream; if(out && !out->stream) { /* open file for writing */ out->stream=fopen(out->filename, "wb"); if(!out->stream) { LOGI("failure, can't open file to write\n"); return -1; /* failure, can't open file to write */ } } return fwrite(buffer, size, nmemb, out->stream); } JNIEXPORT jstring JNICALL Java_com_example_curltest_MainActivity_GetImage( JNIEnv* env, jobject thiz, jstring imageurl,jstring savepath) { CURL *curl; CURLcode res; const jbyte *weburl; weburl = (*env)->GetStringUTFChars(env, imageurl, NULL); if (weburl == NULL) { return NULL; } struct FtpFile ftpfile={ (*env)->GetStringUTFChars(env, savepath, NULL), /* name to store the file as if succesful */ NULL }; //初始化 curl_global_init可以不设置 curl_global_init(CURL_GLOBAL_DEFAULT); curl = curl_easy_init(); if(curl) { curl_easy_setopt(curl, CURLOPT_URL, weburl); // 设置访问链接 curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, my_fwrite); // 设置回调函数 curl_easy_setopt(curl, CURLOPT_WRITEDATA, &ftpfile); //设置回调参数（在回调函数内可以调用) res = curl_easy_perform(curl); //执行获得curl返回参数用于判断成功与否 /* always cleanup */ curl_easy_cleanup(curl); (*env)->ReleaseStringUTFChars(env, imageurl, weburl); if(ftpfile.stream) fclose(ftpfile.stream); /* close the local file */ //清理 curl curl_global_cleanup(); if(CURLE_OK != res) { //失败 LOGI("curl told us %d\n", res); return (*env)->NewStringUTF(env, "failed"); } else { //成功 LOGI("succesful\n"); return (*env)->NewStringUTF(env, "succesful"); } } return (*env)->NewStringUTF(env, "failed"); }
四、创建应用配置文件Application.mk,Android.mk。
在curljni目录下建立文件Application.mk。内容如下:
APP_PROJECT_PATH := $(call my-dir)/project
APP_MODULES := curljni libcurl
在curljni\project\jni目录下建立文件Android.mk。内容如下:
LOCAL_PATH:= $(call my-dir) CFLAGS := -Wpointer-arith -Wwrite-strings -Wunused -Winline \ -Wnested-externs -Wmissing-declarations -Wmissing-prototypes -Wno-long-long \ -Wfloat-equal -Wno-multichar -Wsign-compare -Wno-format-nonliteral \ -Wendif-labels -Wstrict-prototypes -Wdeclaration-after-statement \ -Wno-system-headers -DHAVE_CONFIG_H include $(CLEAR_VARS) include $(LOCAL_PATH)/curl/lib/Makefile.inc LOCAL_SRC_FILES := $(addprefix curl/lib/,$(CSOURCES)) LOCAL_CFLAGS += $(CFLAGS) LOCAL_C_INCLUDES += $(LOCAL_PATH)/curl/include/ $(LOCAL_PATH)/curl/lib LOCAL_COPY_HEADERS_TO := libcurl LOCAL_COPY_HEADERS := $(addprefix curl/include/curl/,$(HHEADERS)) LOCAL_MODULE:= libcurl include $(BUILD_STATIC_LIBRARY) # Build shared library now # curltest include $(CLEAR_VARS) LOCAL_MODULE := curljni LOCAL_SRC_FILES := curljni.c LOCAL_STATIC_LIBRARIES := libcurl LOCAL_C_INCLUDES += $(LOCAL_PATH)/curl/include $(LOCAL_PATH)/curl/lib # 调试用 LOCAL_LDLIBS += -L$(SYSROOT)/usr/lib -llog include $(BUILD_SHARED_LIBRARY)
五、编译生成so库并测试
cd到NDK安装目录下执行一下命令生成so文件
make APP=curljni -B
在android项目中添加
public native String GetImage(String url,String savepath); static { System.loadLibrary("curljni"); }
然后在需要的地方调用GetImage(url,path)进行执行;
这样在path中就可以看到从url保存下来的图片了
