    Hello,

    I'm trying to reload my client from a JS call with document.location.reload(true);
    The page is reloaded but on some (seemingly not all) Android devices I get a Runtime error afterwards in Chrome. Any ideas how to fix that?

    Cheers

    Ok great... when I do an development build the error disappears. But the reload of the page seems to break something... my wrapped inputfields don't open the mobile keyboard anymore. *sigh*

    Interesting... when the text input is broken not even a manual reload of the page helps. But if I switch to another tab and back it suddenly works again.

    This sounds like the browser is running out of memory with the old instance's memory of your app not being collected yet but the browser trying to resevere another big chunk for the new one.

    Do the devices you see the issue on have less memory available compared to the ones you aren't seeing this on?

    The input field issue seems indeed to be odd. Could you please file a bug for this? Thanks!

    I only have three test devices atm so it's hard to tell. I thought about running Application.Quit before reloading the website but as I'm calling the location.reload(); from jslib I don't know how/if I could do that.

    Not 100% sure. What I've tried was from Unity side to first call the JS function that reloads the page and do Application.Quit() right afterwards but the result was that the page didn't reload anymore. I thought that the Quit might destroy the jslib before it executes the reload? I don't know much about JS and how these things work... so maybe the other way around, as you proposed - calling the Unity from JS - would work.

    The reload() function takes an optional parameter that can be set to true to force a reload from the server rather than the cache. Since window.location.reload(true) has been deprecated, changing location.reload(true) to location.reload() to resolve this issue. Also, you can use:

    window.location.href = window.location.href;

    There are multiple ways to Refresh/Reload a page with jQuery/JavaScript, some are:

    location.replace(location.pathname)
    window.location = window.location
    window.self.window.self.window.window.location = window.location
