android - show pictures in webView that are'nt in filesystem

Question

Hello, how can I show pictures in WebView without saving images into file system?

I have tried to implement my custom ContentProvider, but method openFile returns ParcelFileDescriptor that points into filesystem (or socket). My pictures are in filesystem, but in encrypted form.

I have tried also URL.setURLStreamHandlerFactory, but in android java it is useless (because custom streamHandler can be register in jvm that is not allowed).

I also try html code "img src=\"data:image.gif;base64,R0lGODlhiAAkAMQAANOOk...", but in embedded chrome it's not working :(

pls help

There is a bug in Android you cannot load images with Base 64 on a webview like that(ur last approach)...
