Share image

[millordd]

I'm using Capacitor 6.0.3 with @capacitor/share.

According to the docs, ShareOptions supports:

• title
• text
• url (http, https, file://)
• files (array of file:// URLs)

My problem:
I have an image generated in WebView (screenshot) as a data URL / Blob / base64 string.
I want to share this image using Share plugin without manually creating a file URI.

What I tried:

• Passing data:image/png;base64,... to url → not supported
• Passing blob: URL → not supported
• Creating File object in JS → native layer can't access it
• navigator.share → unreliable in Android WebView

Current working solution:
Save base64 to Filesystem (Cache) → getUri → Share.share({ files: [uri] })

Question:
Is there any supported or recommended way in Capacitor 6 to share an image
directly from memory (base64/blob) without writing it to the filesystem,
or is writing a temporary file the only correct approach?

Environment:

• Capacitor 6.0.3
• @capacitor/share 6.0.3
• Android WebView (Ionic/Capacitor app)

Hey @millordd, as mentioned in the Android documentation, a URI is expected to create the Share intent.

In other words, if you want to share binary content (image, video), etc., you'll need to do what you have currently, which is the correct approach: Save the base64 image to a file (e.g. using @capacitor/filesystem plugin), and then pass that file URI to the share plugin files attribute.

I believe that answers your question, so I'll be closing your issue. Feel free to re-open if you require more information.
Thanks!
