Harmony HDC

Reference for controlling HarmonyOS devices with raw hdc commands.

Execution Constraints

• Use hdc -t <device_id> whenever more than one device is connected.
• Confirm screen resolution before coordinate actions: hdc -t DEVICE shell wm size.
• Ask for missing required inputs before executing (device id, bundle/ability, coordinates, file paths).
• Surface actionable stderr on failure (authorization, cable/network, tcp mode).
