- It fixes the toolchain at Kotlin 2.0.21, Gradle 8.9, and Android API 34, returning screenshots at t+2s, t+3s, and t+4s.
Field notes
The service describes a stateless build path: submitted files are written into a fresh Gradle project rather than an existing workspace. Its output is designed for both automation and inspection, combining short-lived screenshot URLs, process logcat capped at 200 lines, total wall-clock timing, and a WebSocket emulator stream. The stated environment is pinned to Kotlin 2.0.21, Gradle 8.9, and Android API 34.
