    To detect the browser architecture you must usenavigator.platform

    console.log(navigator.platform);

    In Firefox Mobile for Android the values ​​can be, for example: Linux i686orLinux armv7l

  2. To complement Marcos' answer, this can work even on an Android WebView, for this we add:

    console.log(navigator.platform);

    or an alert

    alert(navigator.platform);

    It is essential to enable the execution of JavaScriptand also configure a WebChromeClientto obtain the architecture information:

        WebView webView = (WebView)findViewById(R.id.webView);        
    webView.loadUrl(< url de página web >);
    webView.getSettings().setJavaScriptEnabled(true);
    webView.setWebChromeClient(new WebChromeClient());
