Investigate support of GMA Next-Gen SDK

[YuriyVelichkoPI]

Motivation

Google introduced new GMA Next-Gen SDK on Android.

Prebid SDK should support it.

Objectives

• Investigate the compatibility level of the current GMA SDK and Next-Gen SDK on Android.
• Document the level of support of this SDK by Prebid SDK
  • Bidding Only API
  • Rendering API
  • Rendering Delegation
  • Integration via Event Handlers
• Introduce tasks to support Next-Gen SDK on Android

An investigation into the interaction between the GMA Next-Gen SDK and the Prebid SDK produced the following findings:
- Bidding Only API
Currently, Bidding Only integration is not supported. The Prebid SDK does not yet handle GMA Next-Gen SDK request objects. The Next-Gen SDK introduces a new set of request classes with renamed types and a slightly modified API.
Handling these requests should be similar to the current GMA SDK integration, with one notable difference: the customTargeting field (previously used for keywords) is now immutable. This limitation can potentially be addressed by using reflection or by populating targeting values through the request builder.
- Rendering API
No issues are expected with the Prebid Rendering API when used with the GMA Next-Gen SDK.
- Rendering delegation
The API has not changed significantly, so creating a plugin for the GMA Next-Gen SDK should be feasible without major issues.
-Integration via Event Handlers
Dedicated event handlers must be implemented specifically for the GMA Next-Gen SDK.

Additional Issue: Internal Test App
In the InternalTestApp, both the GMA Next-Gen SDK and the GAM SDK cannot be used simultaneously due to duplicate classes in the same namespace, resulting in a dependency conflict. To resolve this, a separate demo application or app flavors within the existing app should be created.

Proposed Tasks

• Add support for the GMA Next-Gen SDK to the Prebid SDK
• Create testing/demo environment for GMA Next-Gen SDK + Prebid
• Create Event Handlers for the GMA Next-Gen SDK
