Android create .aar files using different Facebook SDK versions

Question

I would like to build my app client side compatible with both Facebook Android SDK 3.x and 4.x since Facebook Android SDK deprecated "Session" class.

How can I write the build.gradle to create one aar file for v3.x and one for v4.x.

Thanks.

You can use flavors.

Just define your flavors in the build.gradle

android {
    ....    

    productFlavors {
        flavorSdk3 {
            ...
        }


        flavorSdk4 {
            ...
        }
    }
}

Then you can use different dependencies for your flavors:

dependencies {
    flavorSdk3Compile "..."
    flavorSdk4Compile "..."
}
