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

Capture the device screen as a PNG. These call app_screenshot.

Screenshot​

func (d *Device) Screenshot(ctx context.Context, path string) ([]byte, error)

Screenshot captures the screen as PNG. With a path it also writes the file; without one the bytes come back over the wire.

Examples​

Save a screenshot​

// With a path the file is written, and the PNG comes back too.
png, err := dev.Screenshot(ctx, "screen.png")
if err != nil {
	return err
}
fmt.Println(len(png), "bytes")

The same call from the command line, mobium screenshot -o screen.png, printed on an Android 15 emulator:

saved …/screen.png (153875 bytes)
