Android - html input loses focus when soft keyboard opens (ASP.net)

Question

I\'ve written a web-page login form in ASP.net.

Using a Nexus 4, stock Android 4.2.1, native Chrome browser - when I click on the fields,

Answer 1

I had custom code in my $(window).resize(..) that I wanted to keep, and I wanted to restrict this workaround to only the specific use case being impacted (Android mobile only, Text Input or TextArea focus), so I came up with this:

function isAndroidTextInputFocus() {
    var userAgent = navigator.userAgent.toLowerCase();
    var isAndroid = userAgent.indexOf("android") != -1;

    var result = (isAndroid && 
             ($("input[type=text]").is(":focus") || $("textarea").is(":focus"))     
           );

    return result;
}

and then I tweaked my $(window).resize(..) like this:

$(window).resize(function(e) {
    if (!isAndroidTextInputFocus()) {       
        // ... Proceed with my custom Window Resize logic
    }
});
