-cocos2d-x version: 3.13.1
-build tool : Android Stdio 2.2.3
-NDK version: r10c
-VS version: 2013
-targetSdkVersion 22

I built it with 3.13.1
In all functions that call ‘curl_easy_xxx’
An error occurred next.

How did you get Cocos2d-x? .zip from our website or clone from GitHub?

3

from cocos website

And
The curl build did not work in that state.
so,


I have downloaded the link above. And overwrite.

I solved the problem.
After downloading from Cocos site
Cocos2d-x-3.13.1 / cocos / Android.mk

Include $ (CLEAR_VARS)
LOCAL_MODULE: = cocos2dx_static
LOCAL_MODULE_FILENAME: = libcocos2d
LOCAL_STATIC_LIBRARIES: = CocoStudio_Static
LOCAL_STATIC_LIBRARIES + = CocosBuilder_Static
LOCAL_STATIC_LIBRARIES + = Cocos3D_Static
LOCAL_STATIC_LIBRARIES + = spine_static
LOCAL_STATIC_LIBRARIES + = cocos_network_static
LOCAL_STATIC_LIBRARIES + = audioengine_static
LOCAL_STATIC_LIBRARIES + = cocos_curl_static <- this
Include $ (BUILD_STATIC_LIBRARY)

I added the following.

But


The downloaded libcrypto.a, libcurl.a, and libssl.a files
It did not build.

Error: undefined reference to getpwuid_r "

There was a mistake.
It was a problem of api level.
Compatibility with other libraries is a problem.
Raising or lowering the api level caused problems elsewhere.

Finally, Android applied curl 7.48.0.
IOS was applied as 7.5.0.

I’ve faced in Cocos2d-x 3.13.1 cURL issue in Android platform.
How can I fix it?

This is an API level issue.
You may be able to resolve this by setting API level.
I can not change the API level in my case
For Android, I used the curl version of 7.48.
