Selection curl library. Compile the following steps:
1. Download curl Source
Download: https://curl.haxx.se/download.html
I use a curl-7.46.0
2. Create a file called jni folder name,
And extract just downloaded into the library, and was named curl
3.jni folder created Android.mk, reads as follows:
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)
4. jni folder, create Application.mk, reads as follows:
APP_ABI := armeabi-v7a arm64-v8a5. At this time, the directory structure is as follows:
jni
|-Android.mk
|-Application.mk
|-curl(这里为curl源码目录)Creating curl_config.h under jni / curl / lib /, reads as follows:
