Hello.

The File Web Share Target API is a new, powerful feature in Chrome Canary that allows web apps to receive files (like images) shared from other apps, much like native apps. This post details how I implemented this API on my blog, enabling direct image uploads from my Android camera app. The process involves declaring support for file sharing in your web app manifest and handling the incoming file data in a service worker. The API uses a progressive approach, leveraging standard form POST requests, making integration relatively simple. This feature significantly enhances web app integration with the host operating system, closing the gap between web and native apps.

I successfully tested sharing a photo directly from the camera app to another app. Check it out!

This blog post is a test of the Android Share Target API and its file sharing capabilities. If the image displays successfully, the test is considered successful.
