gdx-pay: "包 com.badlogic.gdx.pay 不存在"

Question

I'm trying to implement gdx-pay in my libgdx project. So I followed the Integration example with resolvers from the libgdx wiki.

I have created a class PlatformResolver in my core project and a class AndroidResolver in my android project (as in the wiki). Both classes import com.badlogic.gdx.pay.PurchaseManagerConfig , but for my AndroidResolver I get a compiler error:

Error:(6, 28) error: package com.badlogic.gdx.pay does not exist

I have imported the gdx-pay-0.4.0-library.jar (which includes com.badlogic.gdx.pay.PurchaseManagerConfig ) to my core project and gdx-pay-android-openiab-0.4.0-library.jar , gdx-pay-android-0.4.0-library.jar , gdx-pay-android-ouya-0.4.0-library.jar to my android project.

As the android project also compiles the core project, PurchaseManagerConfig should be available to the android project, too, shouldn't it?

project(":android") {
    apply plugin: "android"

    configurations { natives }

    dependencies {
        compile project(":core")
        // ...
        compile fileTree(dir: 'libs', include: '*.jar')
    }
}

Any ideas what's going wrong?

EDIT:

When I add gdx-pay-0.4.0-library.jar additionally to the android project (folder android/lib), everything compiles fine (still no idea why it's neccessary). But then I could never restore or buy items because of

I/ERROR﹕ gdx-pay: requestPurchaseRestore(): purchaseManager == null

But this seems to be a ProGuard problem. Without ProGuard I get:

I/IAP﹕ IAP: gdx-pay successfully instantiated.
I/﹕ gdx-pay: installed manager: OpenIAB/null

Although my project compiles now, I nevertheless would be glad if somebody could explain me why I have to add the jar file twice because that could help me understand some other gradle issues.

Try this:

In build.gradle:

project(":android") {
apply plugin: "android"

configurations { natives }

dependencies {
    ***
    compile "com.badlogicgames.gdxpay:gdx-pay-android:0.9.2"
    compile "com.badlogicgames.gdxpay:gdx-pay-android-openiab:0.9.2:library"
    compile "com.badlogicgames.gdxpay:gdx-pay-android-ouya:0.9.2:library"
}

}
