Share an Activity that can be directly inherited on the interface to be photographed, with detailed annotations and activity annotations.

You can directly inherit the Activity based on your project requirements on the page to take a photo. The Activity is accompanied by a detailed annotation. The photo cut topic will be explained in detail, and the finale will provide a complete summary,
