Currently I using Xamarin Forms 5 (preview) and targeting Android 8.1 with the latest Lottie installed (3.5.0 for XF and 4.0.8 for Android)
I'm wanting to add some seasonal themes to my app and was looking to "overlay" a Lottie animation on top of the pages. Currently I use Lottie for a splash screen and it works great, but I cant work out how to apply something app wide.
Setting InputTransparent="True" basically means the control does not intercept the user input. Therefore any control under it will work as expected.

I have implemented the Lottie animation splash screen on android with the new Intent, is there a way to do the same in iOS.
I know LaunchScreen.storyboard is unable to do this, but is there a way to generate a new UIViewController show it on screen with Lottie animation, and while the animation is playing in I will prepare Xamarin App in background task, and when animation ends call LoadApplication(app).
Or is there any other way to start playing Lottie animation first when you launch your app on iOS ?
Setting Lottie animation as the main page in Xamarin Forms is not an option, waiting on Xamarin Forms to start the app will take a few seconds and during that time I wanna show animation, not after.
iOS Launch screen can't animate. If startup time is an issue, and you want to show some animation, would need to write some "native code" (Xamarin.IOS is fine) that does an animation, while you have a background task do Xamarin Forms Init and load App ResourceDictionary. Details TBD, if someone demonstrates that they actually have a serious iOS load-time problem with Xamarin Forms.
OP (Original Poster) tested the time on iPhone, and concluded that it was fast enough to not be worth doing an animation to make that time more interesting. (On typical Android devices the startup time was longer.)
I have tried my UWP app on XBOX one which is built using xamarin.forms and it works generally fine but by default mouse mode is active. I changed it using
RequiresPointerMode = Windows.UI.Xaml.ApplicationRequiresPointerMode.WhenRequested;
on UWP level in app.xaml.cs and it disabled mouse pointer but problem is that using game pad, i am not able to select items on the UI. I can navigate through textbox and buttons but not Toolbar (Commandbar in uwp), ListView, Masterdetail, Tabs etc.
I created a blank native UWP application and added a commandbar with AppBarButtons and NavigationView with NavigationViewItems. It perfectly works, I am able to navigate between menu items and commanbaritems using mouse pad.
Why this is not working for Xamarin.Forms? is xamarin.forms not actually native for UWP?
Xamarin.Forms MasterDetailPage was written before NavigationView existed and it doesn't use it at all (and especially not with NavigationViewItems, that would limit the flexibility, i don't think it will ever be used).
As SplitView has some focus bug that I can confirm it doesn't come as a surprise that it doesn't work with XBox as expected. However UWP doesn't grant that the app will work properly when you disable the mouse mode with native controls, that's why it is enabled by default. There are properties like XYFocusLeft that must be set if the app is not working properly. You probably need to make custom renderer to expose those properties and set them right. That's pretty much of work to do but it is up to you to decide...
Hi I am building a magazine viewer and I need to zoom and drag the content pages. I am using scrollview but I guess the zoom works only for ios. Is there any workaround for this? I am using Titanium 5 sdk, and don't found modules that support it.
On Android you might be able to use http://docs.appcelerator.com/platform/latest/#!/api/Titanium.UI.ImageView-property-enableZoomControls
In wp8 (and wp7) there are 5 types of page transitions: RollTransition, RotateTransition, SlideTransition, SwivelTransition, TurnstileTransition.
But i want make transition between pages like Android transition use control ViewPager.
Is it possible?
For doing Custom Animation you can use storyboard class in wp8 as well as windows 8.And if you want do it in simple way you have to use Microsoft Blend for VS 2012. In which you have to open your project in blend and make new storyboard that you can call in your project. you can see this storyboard in XAMLpage.
I just wondering how to make panorama start-up animation like music+video or picture app. Notice the sliding 3d animation when we open music+video/picture/marketplace app.
When I create panorama project using VS 2010 Express, the animation is just from right to left.
How do i make that animation?
If I understand you correctly - take a look to Wp7 silverlight toolkit - page transitions
The animations are there, but if you have too many things running on the UI thread, the animation will be hard to see since loading will be choppy. To test this, just make a new page with a default panorama inside it and observe the animation while its empty. Zune app will always be faster, its run on native code from my understanding.
