In my app, I am doing navigation using springboard features link and by creating task-flows. Navigation is working good but a blank white page appears for some seconds and page shows with some flick-rings when redirecting. Is there any way to get rid of this annoying thing.
One thing worked for me was changing theme. I just changed theme name to mobile fuision and now there is no white screen.

I use tabbed page and have way more than 5 items in my TabbedPage (15 of them). Now when each ContentPage I navigate to is in within first 4 items, my toolbar renders correctly, displaying the icon and allowing user to interact. The problem begins when I have to go to "... More" tab.
Once I select one of the ContentPages there I don't see the same Toolbar with ToolbarItems in it. Rotating the device to Landscape and back brings the ToolbarItems back.
I have scoured the internet looking for an answer but I can't find much about this particular issue.
Could y'all smart folks point me to a solution to my problem?
I made a simple test but did not reproduce your issue .
What is the version of Xamarin.Forms ? And What specific device did you test on ?
I have an interesting issue with an IOS app, 32bit at present.
I have a simple project with one form, a button and a TWebBrowser component.The "onclick" of the button sets the align property of the twebbrowser to client and opens a webpage (www.trademe.co.nz for testing).
Every thing works ok until I go to use the virtual keyboard (e.g. enter a search). When the virtual keyboard appears I am getting a second "done" button bar appearing above (and behind?) the main one. The main "done" bar includes next and previous buttons, whereas the background one doesn't. It appears that there are two keyboards appearing. I have the issue on both my test phones, one running IOS7 and the other running IOS6 and I believe it is also happening under IOS8.
Does anyone have any idea what causes this?
TIA
Since I have upgraded jQuery Mobile to 1.3 and PhoneGap to 2.5, I have a problem for page changing in my iOS application.
When I click to a link, for a few milliseconds, I see a "no page" state. It's not a white screen, but the background of my "body" element.
I have made some researches on the web, but it looks like no tricks work for me. Most of them tell to disable transition of jQM. But it is already the case for me.
I have tracked jQM event to see what happens, and apparently when I use the method changePage(), it hides the current page, and then show the final page. And during these two methods, I can see this "no page" state, with my body background.
So it is not the flickering navigation that occurs during transition (because I disabled transition), it's something else.
Anyone would have a suggestion to fix this annoying problem (I cannot post image with my reputation)?
This issue has some suggestions on changing the $.mobile.defaultTransitionHandler to use the simultaneousHandler instead of the default sequentialHandler.

This has improved page transition speed in my application (with $.mobile.defaultPageTransition set to 'none'), but I am still dealing with occasional white flashes.
I'm building an iOS wrapper application for a web page, which was built using Bootstrap, at the top of my web app is a .navbar div, not fixed or anything and displays perfectly on first load.
The problem starts when I touch an input, type and then hide the keyboard. Once the keyboard has hidden the page has been moved back down, but the navbar is nowhere to be seen.
It turns out this was caused by a bug in the CSS code which gave a margin to the body. The simplest way to fix this was to change the CSS. Although I'm still none-the-wiser as to how control the UIWebView in such situations.
i'm developing a simple three tabs app for Android and iPhone, using IBM Worklight as framework. Every tab links to a div with data-role="page", as jQuery Mobile specifications.
If I implement the jquery fixed persistent tabbar like is explained there (http://jquerymobile.com/demos/1.2.0/docs/toolbars/footer-persist-a.html), i'm encountering some flickering on the tab item in page transition (with any transiction effect).
If I set the default transition to "none", I could resolve this problem, but I lost the transiction native-like effect.
This behavior appears only if i test the App with a real android device (Xperia Neo, GS2).
If i navigate trough the pages of http://jquerymobile.com/demos/1.2.0/ with my smartphone, especially here: http://jquerymobile.com/demos/1.2.0/docs/toolbars/footer-persist-d.html i can't see the strange behavior, but the footer won't be persistent trough the pages, it just re-render like the whole content and this is worse (this happen with the stock browser or Dolphin, instead looks very well by using Chrome).
Is there a way to improve this effect or there is another way to implement fixed persistent tab bar?
I used as reference the default Android Contacts App.
Maybe you're getting this flicker because you're navigating between pages using rel="external". Try to pass from one page to the other without ajax and you'll see that flickering will dissapear
The problem is due to poor performance of the WebView of the Android environment in rendering 3d transition.
Solved by removing the transition effect with:
$.mobile.defaultPageTransition = "none";
Something else that could help is putting these attributes in the AndroidManifest.xml:
<supports-screens
android:anyDensity="true"
android:largeScreens="false"
android:normalScreens="true"
android:smallScreens="false"
android:xlargeScreens="false" />
<application
android:debuggable="false"
android:hardwareAccelerated="true"/>
