Hi,
I am pretty new here as a “signed user” but I have been using cocos for over 4 month now.
I am currently trying to build cocos using the new gradle-experimental plugin, and it has been quite a chore. I am not yet done but still, things are building up. (note that I am using the gradle-experimental-0.6.0-alpha3 version atm)
I just wanted to share my progress (and get a bit of help if you feel like so).
Here are some basic references for building:
- (gradle 2.9 documentation) https://docs.gradle.org/current/userguide/nativeBinaries.html
- (gradle experimental doc, very messy) http://tools.android.com/tech-docs/new-build-system/gradle-experimental
Here are the build.gradle file I have at the moment (many errors in linkage, but no syntax/ compilation error):
apply plugin: 'com.android.model.library'
model {
repositories {
libs(PrebuiltLibraries) {
chipmunk {
headers.srcDir "../../../../external/chipmunk/include"
binaries.withType(SharedLibraryBinary) {
//
// NOTE: this block should be "StaticLibraryBinary"/staticLibraryFile - but SharedLibraryBinary works and StaticLibraryBinary doesn't as of 0.6.0-alpha2
// bug reported here: https://code.google.com/p/android/issues/detail?id=196065
//
sharedLibraryFile = file("../../../../external/chipmunk/prebuilt/android/${targetPlatform.getName()}/libchipmunk.a")
}
}
freetype2 {
headers.srcDir "../../../../external/freetype2/include/android/freetype2"
binaries.withType(SharedLibraryBinary) {
sharedLibraryFile = file("../../../../external/freetype2/prebuilt/android/${targetPlatform.getName()}/libfreetype.a")
}
}
curl {
headers.srcDir "../../../../external/curl/include/android/curl"
binaries.withType(SharedLibraryBinary) {
sharedLibraryFile = file("../../../../external/curl/prebuilt/android/${targetPlatform.getName()}/libcurl.a")
}
}
}
}

Setup in android-studio is pretty straightforward and will not be covered here except for 3 points:
1°) be sure to use:
distributionUrl=https\://services.gradle.org/distributions/gradle-2.9-all.zip
in your gradle-wrapper.properties
2°) be sure to use gradle-experimental in your general top-level gradle file:
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle-experimental:0.6.0-alpha3'
}
}
allprojects {
repositories {
jcenter()
}
}
3°) The build.gradle file I have posted should be a replacement of the one found in
cocos/platform/android/libcocos2dx
I will keep this post updated as I progress. For now I am stuck on the network folder building (it uses an Android.mk file), and I have not yet decided if I should make it a sub-project with its own build.gradle file.
As I said, it doesn’t quite compile yet (link error due to MANY things)but I am slowly building the file up. Any help would be appreciated.
I may submit a pull request when it’s finished, so everyone can enjoy the new ndk support in android-studio 
Thanks!
