I see WebView flash white on 3.0 - 4.0 (inclusive) if GPU acceleration is on.
This happens even if the WebView's Android background as well as <body> background are set to black. Disabling GPU acceleration in the manifest fixed the issue for me. This appears to be fixed in the official 4.1.1 (Galaxy Nexus), where GPU accel can be kept on, and the white flash does not happen. -- K 2012/8/29 Marina Cuello <[email protected]> > Hi to all! > I have a little app with a layout that it's something like this: > > <FrameLayout> > <FrameLayout> > <ImageView/> > <ProgressBar/> > </FrameLayout> > <LinearLayout> > <WebView/> > </LinearLayout> > </FrameLayout> > > I initially set the ImageView (kind of a place-holder) and the > ProgressBar visibility to VISIBLE and the WebView's one to INVISIBLE. > Then I call loadUrl on the WebView.
