Android gradle will not copy so in jinLibs of grandson NDK module, how can I handle this elegant?

[Xu Deheng]

My dev environment:

gradle plugin: com.android.tools.build:gradle:3.1.3

ndk-sdk: android-ndk-r13b

OS : macOS 10.13.6

AS: 3.1.3


My project archetecture:



Project:

app

|------ndka

|-------- ndkb
|----src
|-----main
|-------jniLibs
|---armeabi
|-------libopenssl.so



Module relationship :

app -> ndka (jni) -> ndkb (pure c/c++)


After building , there are no libopenssl.so in APK. But so lib files in ndka/src/main/jniLibs all be there.


Now, I add ndkb/src/main/jniLibs to ndkb build.gradle files in `sourceSets.main.jniLibs` .


But I think it's not elegant.


Anybody get a better idea for this?? Show it to me, plz.

Is openssl built by gradle?
If not, I don't think there is another way but using sourceSets

I think the problem is the ndka and ndkb directories. Gradle is not
expecting those. In my project, the path is Project/app/src/main/jniLibs.
Gradle finds that path by default. Here is a discussion that has some good
suggestions:
