将Gradle构建模块作为.aar放置在另一个模块的libs文件夹中

Question

I have a two module in project: app and library. Is it possible with gradle to build the library module as .aar and put it in the libs folder of the app module ? I want to do it for release purpose so that the library code will not be exposed.

Answer 1

Yes it is possible. I receive some projects from one of our vendors that are setup this way to prevent the sharing of their library code:

I think the important points are as follows.

In the app level Gradle file:

dependencies {
    fileTree(include: ['*.jar'], dir: 'libs')
    ...
    implementation(name: 'applib', ext: 'aar')
}

The file applib.aar is placed in app/src/main/libs :

In the lib level Gradle file of applib:

apply plugin: 'com.android.library'

After building the library applib, the .aar will be placed in:

build/output/aar/applib.aar
