Rebuilding Android library

[aristotaloss]

I'm trying to fix up a few things but I'm not familiar with Haxe at all, neither with lime or the ecosystem in general.

Rebuilding lime works, but trying to rebuild ndll/Android/liblime-v7.so with, I presume, lime rebuild android -release -armv7 gives the following:

x86 Platform: 16
arm Platform: 16
x86_64 Platform: 21
arm_64 Platform: 21
Frameworks should set the minSdkVersion for each APK to these values.

I've dug through the code but I can't find much - it seems that Android building is disabled in CI too. How do I go about this?

I have the same problem. :( How to fix that? Does anyone has any idea?

Looks like to have to use Android NDK 15c.

[jgranick]

This is primarily an issue with HXCPP support of newer Android NDKs

Once HXCPP adds newer NDK support we can fine-tune any changes on the Lime side required for the clang toolchain on Android

[pecheny]

Last hxcpp seems being able to deal with NDK >= r20. Unfortunately i could not build lime: there were a lot of errors during openal and pixman compilation. I guess the reason is clang and its toolchain compatibility.

When i removed openal, pixman and cairo flags from build.xml, lime had built but heroku shader demo crashes with lack of dependency methods like

ps: this line seems incompatible, i commented it out AndroidPlatform.hx:287// if (armv5) commands.push(["-Dandroid", "-DPLATFORM=android-16"]);
