pauseTimers only affects js, and this has nothing to do with js, so that's expected It's debatable whether onPause should do this though. There are more uses for http-equiv="refresh" other than periodically refreshing the page, and breaking those use cases would probably be bad. What's your use case in your app? Why not just load a different page?

I agree it has nothing to do with JS but I couldn't find any other API to stop the background data Use case is that when application goes to background it should not consume data. Is there any other API I can use which can help me with this?

Are you in control of the page being loaded here? You can always load about:blank or destroy the webview when going into the background. Webview in general does not have any API to control data. There are lots of other ways for the webview to keep consuming in the background, depending on what the page is doing. At this point, it's impossible to even keep track of this at the app level, let alone controlling all the edge cases. Android N has a os-wide data saver feature. I'm not sure what it does precisely, but that's probably the way to go for these things.

We are not control of the page being loaded here. Loading about:blank or destroying the webview will not let it resume when the application comes to the foreground.

Then you are out of luck. There is no "pause data" feature. Sorry.
