About this project
A Kotlin UI agent SDK for Android projects. TypeSafe Jev or DeepSeek selects actions from the actual controls on the current screen, and an Android accessibility service executes them. Each backend can drive a task independently: use a DeepSeek API key without a Jev account, or use a TypeSafe key for Jev. The repository includes a sample app and a local test screen that requires no app account.
Quoted from the project's README. Read the full README.

Highlights
- Builds a dynamic action table from accessible controls with allowlists, budgets, confidence gates, and duplicate guards.
- Separates long-click on advertised actions from timed press-and-hold with host-controlled duration limits.
- Observes effects after acceptance with settling windows and records recent effects for the next decision.
- Includes a sample app with presets and a local test screen needing no app account.
Watch out
Unstable API not published to Maven Central; rebuild core, SDK, sample, and host together and do not swap single artifacts. Copy reviewed against the repository README on 2026-10-04, not from running it.
Questions about this entry
Short answers drawn from the linked project or page.
Either backend drives the same loop independently. Jev uses multiple questions in one request while DeepSeek uses a strict select_action function over enumerated action ids, and only the selected provider key is needed.
It cannot. Text comes only from named exact candidate values supplied by the host, the model chooses a text key, and geometry, duration, and coordinates stay under host or SDK control.
It re-reads and compares fingerprints before acting, refreshes and asks again on change up to three times, excludes no-effect combinations on the same page, and stops after two sub-threshold or duplicate replans.
No. Accepted means Android took the action, not that the goal was reached. DONE is only the model claim; the task returns verified only when a supplied outcome verifier passes, otherwise unverified.
LONG_CLICK invokes a control's advertised Android ACTION_LONG_CLICK, while LONG_PRESS holds a touch at the center of a currently observed, visible, actionable control; the host sets the hold via Task.longPressDurationMillis (default 2,000 ms, range 500-5,000), and the model cannot supply coordinates or duration.
It does not support screenshot-based vision, guessed coordinates, arbitrary gestures beyond press-and-hold, general WebView or Canvas recognition, password entry, text generation, lock-screen operation, or unattended long-running background tasks.
The API is still unstable and it is not published to Maven Central; the coordinates work only with the local Maven repository this project generates, and you must rebuild core, SDK, sample, and host together rather than swapping a single artifact.

Closed weights have not stopped the ecosystem from rebuilding the shape in the open. API-compatible servers, retrained heads on small models, and inference-time tricks that skip generation entirely.
