Using cURL in Android

Question

I would like to use cURL library in my android application in native code (using NDK r5b, the latest). After researching online, it seems the only way to use cURL in android

Answer 1

After check all possibles post about this, I finally got a good compilation using a Linux x64 machine and Curl version 7.37.0 at path ${android-ndk-r10}.

Maybe this steps can help you:

1º

${android-ndk-r10}/build/tools/make-standalone-toolchain.sh --platform=android-15 --arch=armv7-a --toolchain=arm-linux-androideabi-4.8 --install-dir=./tmp/android-15

2º

export CC="${android-ndk-r10}/external/curl/tmp/android-15/bin/arm-linux-androideabi-gcc"

3º

./configure --host=arm-linux --enable-cross-compile --enable-threaded-resolver --disable-shared --disable-ftp --disable-file --disable-ldap --disable-ldaps --disable-rtsp --disable-dict --disable-telnet --disable-tftp --disable-pop3 --disable-imap --disable-smtp --disable-gopher --disable-manual --enable-proxy --enable-ipv6 --enable-cookies --enable-symbol-hiding --disable-versioned-symbols --disable-soname-bump --disable-sspi --disable-ntlm-wb --prefix=${android-ndk-r10}/external/curl/build/curl-7.37.0

4º

make -j4

5º

make install

You will get a build version at ${android-ndk-r10}/external/curl/build/curl-7.37.0.

If you are using a 64bits machine to compile, maybe 2 defines are bad, and you get this error:

error: size of array '__curl_rule_01__' is negative

I solve redefining the variables in file ${CurlbuildAndroid}/include/curl/curlbuild.h (Its dangerous to do this, but it worked!):

CURL_SIZEOF_LONG 4
CURL_TYPEOF_CURL_OFF_T 4
