Hi,

In my app, i create an image on canvas in webview context.

What would be de best way to save it to a file?

thanks!

I can't think of any way to do it.

I have an idea in the back of my mind there may be a way using base64 but I can't bring it to mind.

Maybe something like this:

Hi all,

In first place thanks you your answers Steve and BareK.

Well, I tried everything (Anchor tag with download attr; app.WriteFile withy "base64" on encoding param; and anything else) and didn't work.

So, i made a "workaround" that worked and here it goes, in case someone needs that too:

1° - I create a new webView and add it to the main app layout;

2° - The canas has to cover 100% of the height and width, of the new webView;

3° - Draw everything i need on the canvas;

4° - I save the image using: web.Capture("/sdcard/MyDrawing.png");

5° - Close the webView;

PS. On attach goes the full app (Just an example).

Best regards to all.
