The Titanium Android app below sets the user-agent on a WebView, so the web server can differentiate the Android app from the Android browser. When setUserAgent is used, touching an HTML select will no longer open the input on the bottom of the screen.

Moving this to engineering as I can reproduce the issue with the provided test case and the attached html file. I can only see the issue if webView.setUserAgent is used.
This issue is still occurring in more recent releases of Titanium SDK Using build: 3.4.0.201409261227, SDK 3.3.0.GA and 3.4.0.GA Tested on these devices, but expect it is occurring universally: Samsung Galaxy S3 running Android 4.3, API 18 Samsung Galaxy S3 and S4 running Android 4.4.2, API 19 Motorola Droid Razr running Android 4.1.1, API 16 One additional note/observation: The select pop-up dialog does seem to instantiate, but UNDER the main window. If you close the main window, you are able to briefly view the dialog before the window closes completely. There doesn't seem to be any kind of workaround.
I have the same problem with select on remote sites on android. Without setting the userAgent the select works as aspected.
I just have reproduced this with a current 4.0 build. After using
setUserAgent, the web view behaves as follows: * the touch keyboard does not open anymore when focussing a text field. UsingTitanium.UI.Android.SOFT_KEYBOARD_SHOW_ON_FOCUSallows entering text but provides bad UX since the keyboard does not close when no field has focus. *selectboxes don't work at all. When closing the web view while the box has focus, the selection control can be seen for a very short time before being destroyed: it looks like it is instantiated *behind* the web view and thus not visible. In my opinion this is a grave bug that breaks an important UI component.A quick workaround is to create and add the web view in 'open' event of the window or tabgroup. This is to make sure that the web view is created in the context of the main window.
var tabGroup = Ti.UI.createTabGroup({ exitOnClose: true }); var window = Titanium.UI.createWindow(); var adviceTab = Ti.UI.createTab({ title : "Title", window : window }); window.containingTab = adviceTab; tabGroup.addTab(adviceTab); tabGroup.open(); window.addEventListener('open', function() { var webView = Titanium.UI.createWebView(); webView.setUrl('select.html'); webView.setUserAgent("Mozilla/5.0 (Linux; U; Android 4.0.4; en-us; SAMSUNG-SGH-I747 Build/IMM76D) AppleWebKit/534.30 (KHTML, like Gecko) Version/4.0 Mobile Safari/534.30"); window.add(webView); });Please use the workaround and comment if there are still issues.
