Mobile Jev
Standalone Android agent and React studio for Mobilerun, powered by Jev: Jev selects operations and observed targets, code rejects stale actions, and a CLI, execution traces, and latency measurements ship in the repo. No ADB connection required.

About this project
▶ Watch the demo — Jev opens Uber, enters a route from San Francisco Airport to the Golden Gate Bridge, and reaches payment selection. The recorded task timer shows about 21 seconds for 9 actions. A completed booking is not demonstrated. One goal. A real Android phone. Jev makes the decisions. A standalone mobile agent for Mobilerun, powered by TypeSafe's Jev and the Mobilerun API. Includes a live React studio, a CLI, execution traces, and request-level latency measurements. No ADB connection is required.

Works forJev for Verification
Used inJev for Software & DevTools
Highlights
- Jev chooses OPEN_APP, TAP, TYPE_TEXT, scrolling, navigation, WAIT, DONE, or BLOCKED; code validates the target before Mobilerun executes.
- Operation and compatible-target questions share one request, so unused target answers cannot execute.
- The dark-theme demo re-reads the screen and verifies the switch is on instead of trusting a model DONE.
- The recorded Uber demo shows about 21 seconds for 9 actions; a completed booking is not demonstrated.
- No ADB connection is required, and the studio keeps account API keys on the server.
Quickstart
bash
git clone https://github.com/droidrun/mobile-jev.git

MIT-licensed. Needs Node.js 22.16+ (24 recommended), pnpm 10.30.1, curl 7.70+, a ready Mobilerun Android device, and both MOBILERUN_API_KEY and TYPESAFE_API_KEY; CI runs offline and does not control a phone.
Questions about this entry
Short answers drawn from the linked project or page.
Code executes. Jev chooses an operation (OPEN_APP, TAP, TYPE_TEXT, scrolling, navigation, WAIT, DONE, BLOCKED) plus speculative targets in one request, and Mobilerun performs the action. The executor resolves coordinates from observed bounds, validates the distributions, rejects stale targets, and never retries a device mutation after an uncertain transport failure.
Only exact spans from your goal. Jev selects a span and code copies it into the field; pass --text to override the candidate list. It explicitly does not generate prose or invent missing personal details, so no separate text-generation model is needed.
No, and the README says so plainly. The dark-theme demo re-reads the screen and checks the real switch instead of trusting DONE, and an unverified typed field stops the run rather than retyping. The Uber demo reaches payment selection; a completed booking is not shown.
Node.js 24 recommended (22.16+ supported), pnpm 10.30.1, curl 7.70+, a ready Mobilerun Android device, and both MOBILERUN_API_KEY and TYPESAFE_API_KEY. The studio binds to localhost for a single operator and keeps account keys server-side; CI runs offline tests and never controls a phone. Device and service charges are separate.
Account API keys stay on the server, and the browser receives only device-scoped streaming credentials. The app binds to localhost, validates request origins, and is intended for a single local operator; public or multi-user hosting requires your own authentication and device authorization.
Text comes from exact spans in the goal: Jev selects a span and code copies it into the field, with --text to override the candidates, and it does not generate prose or invent personal details. When the focused field can be read back, replacement uses the faster accepted completion mode and the agent verifies the complete value next observation; an unverified value stops the run without retyping.
Jev opens Uber, enters a route from San Francisco Airport to the Golden Gate Bridge, and reaches payment selection, with a recorded timer of about 21 seconds for 9 actions. A completed booking is not demonstrated, and the model's DONE is treated as a signal rather than proof of success.
