openssl-curl-android

Compile openssl and curl for Android

Prerequisites

Make sure you have Android NDK installed.

And also necessary autoconf and libtool toolchains.

Download

If you do not want to compile them yourself, you can download pre-compiled static libraries from releases. They are in build.tar.gz.

Doing your own compilation is recommended, since the pre-compiled binary can become outdated soon.

Update git submodules to compile newer versions of the libraries.

Usage

git clone https://github.com/robertying/openssl-curl-android.git
git submodule update --init --recursive

export ANDROID_NDK_HOME=your_android_ndk_bundle_root_here
export HOST_TAG=see_this_table_for_info # https://developer.android.com/ndk/guides/other_build_systems#overview
export MIN_SDK_VERSION=21 # or any version you want

chmod +x ./build.sh
./build.sh

All compiled libs are located in build/openssl and build/curl directory.

Use NDK to link those libs, part of Android.mk example:

include $(CLEAR_VARS)
LOCAL_MODULE := curl
LOCAL_SRC_FILES := build/curl/$(TARGET_ARCH_ABI)/libcurl.a
include $(PREBUILT_STATIC_LIBRARY)

Options

Change scripts' configure arguments to meet your requirements.

For now, using tls (https) in Android would throw peer verification failed.

Please explicitly set curl_easy_setopt(curl, CURLOPT_CAINFO, CA_BUNDLE_PATH); where CA_BUNDLE_PATH is your ca-bundle in the devide storage.

You can download and copy cacert.pem to the internal storage to get tls working for libcurl.
