What is the Perkox Android SDK and what does it do?

The Perkox Android SDK is a lightweight library that lets you embed an offerwall — a catalog of rewarded offers, surveys, and tasks — directly inside your Android app. Users complete offers and earn in-app rewards, while you earn revenue per completed action. The SDK handles offer display, tracking, and reward callbacks so you don't have to build monetization infrastructure from scratch.

What are the minimum requirements for the Perkox Android SDK?

The SDK requires minSdk 21 (Android 5.0 Lollipop), targetSdk 33 or higher, Java 17, Kotlin 1.9 or later, and AndroidX libraries. You also need a Perkox publisher account with an appId and sdkKey from the dashboard.

Can I rely on client-side onReward callbacks for crediting users?

No. Client-side callbacks are useful for UX updates like showing a toast or refreshing a balance, but they are not secure. A user could spoof or replay callbacks to credit themselves without completing an offer. Always validate rewards server-side using Perkox postback URLs with signature verification, and treat client-side callbacks as informational only.

Does the Perkox Android SDK support both Kotlin and Java projects?

Yes. The SDK is written in Kotlin but is fully interoperable with Java. Both Kotlin and Java implementation examples are provided in the official documentation. The API surface (PerkoxOfferwall.create, offerwall.launch, offerwall.onReward, offerwall.onClose) works identically in both languages.

How do I test the offerwall before going live?

Configure your SDK with sandbox credentials from the Perkox dashboard. In sandbox mode, test offers are displayed, postbacks are sent to your configured URL, and no real charges occur. Once you verify the full flow — offer completion, postback receipt, and reward credit — switch to production credentials and publish your app.
