jniLibs are not extended in gradle

Question

An android application have two modules and one depend on the other, and the common used jars and native libraries are defined in parent-project, while the child-project add it as a dependency in the build.gradle:

However after I build the child-project I found that the jars put insiede the parent-project are copied to the apk, while the native libraries are not. Only the native libraries inside the child-project are packaged to the apk.

What's going on?

With Android studio 1.0.2.

Answer 1

I had the same issue. The problem was, in my parent (library) project's build.config's sourceSets I've added the following:

jniLibs.srcDirs = ['jniLibs']
jni.srcDirs = []

This didn't work, .so files were missing from the child project's APK, so I've replaced it with:

jni.srcDirs = []
jniLibs.srcDir 'src/main/jniLibs'

With this method, everything is fine.
