I've searched for examples of iOS app clip & Android instant Apps but could not find more than few examples.
I am looking for released apps in App Store/Google Play or open source examples.
good examples could make developing these new features easier and gives developers new creative ideas to use these wonderful tools.
Do you have an app that utilizes App clip or instant app?
How did this affect your app?
What is the challenges you have faced?
Note: I know this is not a typical question but it need to be asked in a community full of great developers who love to share knowledge with others, and I don't think there is a better place than here.
Intro
I know it's been 10 months since you posted the question but I just stumbled upon it now... I've developed an app called ARShades for both iOS and Android that allows the user to try glasses on via Augmented Reality and I'm still in charge of development. The app supports both Instant App and App Clip, although I'm facing troubles making the the app banner show for the App Clip.
Firebase issues
As far as I can tell developing App Clips is a tad harder than develeloping Instant Apps, I'll tell you why. The main apps for both systems make extensive use of Firebase Firestore and many other features. This isn't a problem on Android where sockets are supported across the board, while on iOS they are only supported in the main app, so I had to use REST API to read and write data on Firebase when developing the App Clip, it's been a nightmare since it was the first time for me dealing with REST APIs (I just finished yesterday and published the update).
App Size
Another issue I faced is related to reducing the app size. On Android I had to remove all the unused images and compress the remamining ones. On iOS I had to separate the asset catalogues between: used only by the main app, shared, and used only by app clip. And of course I went through some compression works there too. I forgot to mention that I developed a new app as Instant App on Android, while you cannot do the same on iOS since it must be in the same project.
App to site linking
Another insidious part was the linking of the site to the apps. I managed to do it on Android by making changes to the manifest and specifying the host, while I can't seem to find a way to link the App Clip to the site in ay way. I've done everything the documentation says. I've put the apple app site association file in the .well-known folder but nothing, no banner shows up. I'll keep working on that.
Edit: Everything is now solved.
Conclusions
So, to sum up, I've found Instant Apps better on the developing and hassle side of things, the support sockets, hence the full suite of frameworks the full apps have. I hope I kind of answered your question, although I think you have documented yorself elsewhere in these past 10 months XD

I notice that desktop support isn't mentioned in NativeScript's future roadmap any more.
Has this been dropped for good, or is it still on the cards?
If it is still on the cards, for when is it planned?
NativeScript under Progress ownership
While NativeScript was owned by Progress, desktop support was never a priority; developer surveys did not show strong enough demand for it, and the NativeScript Core team were stretched too thinly to tackle it as a curiosity.
Of interest, before the death of Windows Phone, NativeScript did get very far on implementing a Universal Windows Platform runtime for NativeScript: https://github.com/NativeScript/windows-runtime
The NativeScript iOS runtime (https://github.com/NativeScript/ios-runtime for JSC, https://github.com/NativeScript/ns-v8ios-runtime for V8) is also close to delivering Catalyst support, although it's essentially undocumented for now.
I spoke with the NativeScript iOS runtime team and they said it would be pretty trivial to generate JS bindings to macOS (AppKit/Cocoa), too – though one would still have to implement all the UI components as AppKit ones, so it would only be the start of the journey.
Unofficial support
Kamen Bundev (on the Progress/Telerik NativeScript team) has been building a Qt-based desktop implementation of NativeScript as a hobby project for a long time:
https://github.com/bundyo/nativescript-platform-desktop
It has access to Node.js's APIs rather than, say, the Obj-C runtime on macOS, however.
NativeScript under nStudio ownership
NativeScript was recently handed over to nStudio, who may have a different stance. This question did in fact receive an official answer recently on Twitter:
They have also expressed love for the idea of creating Windows 10 apps with it (the tweet links to this issue, https://github.com/NativeScript/NativeScript/issues/8643):
My personal speculation
Note that I do not work for nStudio, and the dust is still settling after the NativeScript handover, so everything from here is just speculation:
So I think there's no question that the passion is there – the real question is whether they have the resources to back it. I personally think that there won't be any movement on it anytime soon, as nStudio need at least a few months just to get used to driving the NativeScript ecosystem and sorting out the long-standing open-source frictions. I think that they'd absolutely welcome a community-driven effort on this, of course. I imagine that by 2021 they'll feel more ready to take on projects of that scale.
I've built a simple Xamarin.forms app which connects to a web service and gets one piece of data and displays it.
I wanted to do the same on an apple watch (targetting a series 2 apple watch) but I just don't understand how it works.
I've added the watch project and the watch extension, created the interface... Got a "refresh" button which changes the value of the label to a hard coded value but I want to get the data from a simple web service on app startup on wake and when button is activated (similar to my xamarin.forms iphone app)
I've tried using the classes that I use on the forms app to get the data but I can't reference them. I've tried using httpclient and that doesn't work.
After googling it appears I am suppose to use a HandleWatchKitExtensionRequest delegate in the phone app to get the data in a dictionary and then display the data. I haven't been able to find any really simple examples of this, but I'm confused because since apple watch version 3 the watch has been autonomous with cell access and therefore it doesn't have the host app necessarily.
So what I'm asking, is can the watch actually consume a web service alone using a xamarin phone app and if so, is there any simple examples because I can't find any (that aren't from 2015).
Sorry if this is vague, or I sound like a newbie (I definitely am a newbie when it comes to xamarin but any pointers or help would be appreciated)
According to https://developer.apple.com/documentation/foundation/nsurlsession?language=objc NSURLSession is available since watchOS 2.0. It is used to download the content from the web and is extensively documented just don't search for watchOS specifically as it is the same on all Apple OS.
But as HttpClient uses NSURLSession it is also available, so, maybe you need to add the reference to System.Net.Http.
When I was last developing for the watch I noticed that HttpClient would never work. I had to use NSUrlSession, so this is what helped me.
Hope this Helps
I wonder why none of the Xamarin Prebuilt Apps at https://www.xamarin.com/prebuilt support both iPad and iPhone? They all have the same design on each resolution. Especially Apps like 'Acquaint' would be perfect on iPad to have the contact list on the left and the details on the right. But instead it just has the same design like the iPhone Version.....
Are there any reasons why Xamarin does not offer samples with different designs depending on the client resolution? Are there somewhere else some examples?
Many thanks!
You might want to take a look at our Creating Mobile Apps with Xamarin.Forms Book First Edition by Charles Petzold.
I work on the same team as Charles and I know it's a topic he's covered in detail. The full book should be available soon too.
BTW, we are looking into creating some detailed, annotated cross-platform app samples that do all the goodies that a typical modern app would be expected to have.
I do not know of any of the stock Xamarin examples that use OnIdiom, but it just a matter of time to code them...hahahah, always just a matter of time and code. (I'm sure the Xamarin guys can chime in on this one):
Xamarin.Forms.OnIdiom Class
<OnIdiom.Phone>Vertical</OnIdiom.Phone>
<OnIdiom.Tablet>Horizontal</OnIdiom.Tablet>
In terms of finding examples that use the Xamarin.Forms XAML OnIdiom I would search Github for OnIdiom, there a few OSS examples of phone/tablet switching floating around there as I used at least one as a template to do a quick phone/tablet prototype for a client.
I've recently posted my Android app to Chrome Web Store using ARC Welder, and wondering about how I can make it a paid app.
Currently, for Android, I have a free version and an "unlocker" as a separate app on Google Play. The user installs the free version first, and then if he/she decides to "go pro", he/she purchases and installs the "unlocker" which talks to the free versions and activates it into "pro" mode.
So my questions:
When packaging an Android app with ARC, it runs on its own, so there is no way to have a second app ("unlocker") running in the same Android "sandbox", correct?
Is it possible for an Android / ARC app to access "purchased" state via Google Play APIs, say for checking if the user purchased the "unlocker" app on Android?
I assume that the answer is "no", at least for now:
https://developer.chrome.com/apps/getstarted_arc
Since ARC is in Beta, it doesn't support all of Google Play Services yet.
However, here are some available APIs:
Auth (OAuth2)
GCM
Google+ sign-in
Maps
Location
Ads
I don't see licensing APIs here.
I found these links on monetizing Chrome apps:
https://developer.chrome.com/webstore/money
https://developer.chrome.com/webstore/payments-iap
Even if this also applies to Chrome OS (not sure), it seems to require JavaScript coding to talk Chrome Webstore APIs. Is it possible to access those from inside the Android ARC sandbox?
Are there better options that I'm missing?
None? Should I just wait until Android ARC is fleshed out more and hope that it includes support for paid apps?
The direct answers are:
1) You can bundle up two APKs so they both run in the same sandbox. But only one of them is launched as "your app". It is free to then launch or otherwise use the second APK as it sees fit.
2) But as you noticed, there is no way to easily check for a purchase/license right now.
Your best bet may be to wait for the Google Play Services license APIs to be implemented.
I have some knowledge of basic PHP developing however right now I am thinking about developing a phone app. I do however have a bit of a conundrum in that I love WP7 and I have so many ideas for features which can't be done on iOS and Android, however at the same time I am completely aware that my target users (filmmakers) generally have iOS or android phones.
Is there a way I can develop the app, which I will get a developer to do rather than myself, with WP7 as the lead platform and then make a relatively simple conversion to the other platforms or do apps generally have to be completely reworked for each platform?
Also, just to though it out there, any idea of where to go to find a freelance app developer?
Thanks

I think you have a few options, but the first question I would have is: where comes the data from. Are you the owner of the data, and do you already have a datasource from where you can get the data from? If not I would suggest take some time to write a decent 'backend' from which the different platforms easily can get the data from.
Also all different platforms have their own pro/cons which you cannot share that easily. If you build a WP7 app in silverlight/xna, you cannot directly port it to a ios/android variant, also functionality will probably look/react different. You will need different solutions foreach platform with this approach.
Another option would be to use an platform like phonegap which can create a solution that will work on multiple platforms. (It uses HTML5 to get it work on the different platforms)
Build your app on iOS and android first, and when you have an app to base WP7 development then contact a developer that has made similar apps to yours.
