Record

This tool on every surface: CLI · MCP · Python · JavaScript · Go · Java · .NET

Record the screen to a video: start, stop with a path to save it, or omit the action to ask whether a recording is running. These call app_record.

Record​

public IDictionary<string, object?> Record(string? action = null, string? path = null)

Records the screen: action "start", or "stop" with a path to save the video; neither asks whether one is running. Stop returns the file's frames and duration, read from its own header; a still screen is one frame on Android, which is not a failure. A relative path is this process's.

Examples​

Start recording the screen​

device.Record("start");

The same call from the command line, mobium record start, printed on an Android 15 emulator:

recording — stop it with action "stop" and a path

Stop, and save the video​

var video = device.Record("stop", "flow.mp4");

The same call from the command line, mobium record stop -o flow.mp4, printed on an Android 15 emulator:

saved …/flow.mp4: 54 frames, 1.605s of video, recorded over 1.705s
