Problem with latest android version

I have a problem with the latest android version.
Until now i loaded files from server and saved them to localstorage.
Then i add the imagedata to src member of image.

It worked. But now it work only if I use the URL.
<img src="http://example.com/test.png"/>

But it doesn’t work with
<img src="data:image/png;base64,......."/>

I don’t know why. I didn’t change some code. I only updated the android software to the latest version.
Maybe someone can help me?
