This session will showcase how Volvo Cars is pioneering virtual testing of Android Automotive applications using real vehicle data. Niclas Lind, a superuser at Volvo Cars, will share insights into his workflow, discussing how recorded real-world signals enhance app testing and validation while significantly reducing iteration time. The session will provide a practical guide on leveraging the cloud for emulator testing and highlight the advantages of using real data over simulated signals. This seminar serves as a best-practice knowledge-sharing opportunity on how real vehicle data can streamline virtual validation of in-vehicle applications. Key take aways: Comparing Different Testing Setups: Test rig with traditional tooling, testing in a real car, Using simulated signals in GAS (Extended Controller) vs. recorded signals in the cloud. Demonstration of the Injector Setup:  How signals are injected from the cloud into the emulator for validation. Benefits of a Drive-Cycle Recording Library: How to maintain a library of real-world driving scenarios. Methods to add new signals based on specific needs (drive cycle/types/scenarios). How to inject signals that are difficult to obtain or unavailable (edge cases). Early Testing and Signal Transformation: Using LUA scripting to transform and test signals before implementing them in infotainment systems.Workflow for integrating real vehicle data into virtual environments
