Google Android Build In-App Agentic Workflows
Google's Android Developers Blog has published a technical guide on building in-app agentic workflows for Android apps, using cloud-hosted backends. The post introduces the Agent Development Kit (ADK), along with two protocols: AG-UI for standardizing agent-client communication and A2UI for dynamically describing UI components. Developers can use these to create autonomous multi-agent systems, such as a Booking Assistant in the Jetpacker sample app, that handle complex tasks like booking flights and hotels. The backend agents run autonomously, while the Android client renders interactive UI via Jetpack Compose using the new androidx.a2ui libraries.
Technical release from Google for building agentic AI workflows in Android apps; relevant for AdTech ecosystem as it enables in-app AI-driven interactions and UI rendering, potentially impacting mobile advertising and app monetization.

OpenAI's Path to $25B Ad Revenue: Five Key Hurdles
OpenAI's advertising business, launched seven months ago, is reportedly achieving a $1 billion annualized revenue run rate, with projections of $25 billion in ad revenue by end of this year and $100 billion by 2030. However, advertisers cite significant barriers to scaling spend beyond test budgets. Key challenges include inadequate measurement and attribution, rigid contract terms causing data and liability concerns, insufficient inventory, and the need to expand the advertiser base to include SMBs via integrations like Shopify. To support this growth, OpenAI is partnering with ad tech firms like Criteo and Kargo to broaden reach. Infrastructure development is also critical to meet demand. Industry observers note that OpenAI must address these issues to compete with established platforms like Google and Meta, especially given rising AI safety and privacy concerns.
Meta launches enterprise AI cloud platform
Meta has announced the creation of Meta Enterprise Platform, a new business unit that bundles its AI models, agents, APIs, and infrastructure for enterprise customers and developers.

Positioned to compete with hyperscalers like Microsoft, Google, and Amazon, as well as specialized AI cloud providers like CoreWeave, Meta aims to leverage its massive AI investments—capex forecasts of $130-145 billion for 2026—and its existing reach of billions of users and hundreds of millions of businesses to expand beyond advertising into subscriptions, API access, and compute capacity.
