I want to make a keyboard like SwiftKey Keyboard and Gboard which is also used on Android. It is possible to do such an application with react-native. How to follow a path.
Not sure if this is what you're looking for but I've seen this library used a couple times for making keyboards in react-native: react-native-custom-keyboard

For more context, I'm developing a Augmented Image Android app. Because of a series of unfortunate events, I ended up trying to develop this having absolute 0 Android experience, but here I am. The thing is, I can't find good tutorials on this topic (ARCore in Android Studio), so I am taking Google example apps and trying to understand how they work.
It seems that it enters in detail about OpenGL, but I don't have the time to learn it properly. I found this thing called SceneViewer, which seemed just what I need. An easy way to charge and display a model/scene to my ARCore anchors. But, it seems discontinued. Or for what I have found, it isn't compatible any longer with Android Studio.
Is there anything out there that could serve this purpose? Or Scene Viewer can still do this job?
I am attempting to develop a Wear OS app which is dependent on a paired Android phone to perform some higher complexity computations. To this end I have implemented on the wearable side the proper infrastructure to pass a PutDataMapRequest message to the phone app, where I am having trouble is extending the WearableListenerService class on the phone side. When I alt+enter to see the suggested actions menu, the option to add the requisite library is there. However when I select that option nothing happens and the option is still there afterwards (the error is not rectified). I will caveat this by saying I have only been developing for Android for about 2 weeks so some of this Android Studio and its' quirks are still a little new to me. Prior to this point I had attempted various incarnations of building this app. The first where I had built the apps separately, and on that attempt this same extension caused problems (the IDE didn't even offer any suggestions at that point). I also tried loading the data layer api sample to find an example of the wearable listener service but unfortunately it is only present on the wear side of the app. The original source of this approach was from this tutorial, which I know is a little old at this point (at least one of the calls on the wear side are deprecated which I already worked around). At about 2:00 in the presenter is able to extend WearableListenerService without any issue within his phone side app and I have no idea what I am missing to be able to do that. I also did look into just trying to add the support library manually but to no avail.
Ok so, for anyone who runs into a similar issue down the road. The solution appears to be that when you create a wearable app through the new wizard and attempt to add an application module to the project, you will need to manually add the following lines to your phone app side gradle file under dependencies.
implementation 'com.google.android.gms:play-services-wearable:17.1.0'
implementation 'androidx.wear:wear:1.1.0'
This allowed the IDE to recognize the requisite classes and import them accordingly into the companion phone side application.
I am new to Xamarin and not sure if chose Xamarin.Forms to create a application for ios and android platform has a problem or not.
The application has some features below:
The application will be able to running some code in background without launching application by user.
The application can be launched by a href link or a notification.
The application is able to launch a builtin Camera application, and receive picture data from Camera application.
Thanks,
Bo
The features you are mentioning can be done with both. Actually, anything you can do on Xamarin.iOS and Xamarin.Android can be done with Forms. Because Forms is only an abstraction layer for the UI which is installed by a NuGet package.
Now, having that said when to use Forms or when to use iOS/Android? It is mostly about UI. Are you going to do some advanced or platform specific stuff is is easier to implement that with the platform specific project.
If you UI will be the same in both platforms and mostly consists of some lists and input fields, then that is a very good candidate for a Forms project.
Notice how I said it is easier to do in the platform specific projects. Again here, you can do anything in Forms as well by the means of Custom Renderers, it is just a bit harder to do.
Ideally try it out yourself and see what suits you best.
In regard with your need to execute code in the background. This will be tricky and is very dependent on the platform that you're on. You will definitely have to write platform specific code for that for which you can use the DependencyService to abstract it to your shared code.
However like AlancLui mentioned executing code in the background isn't something that is easy to do on mobile. On iOS it is restricted to accessing location data or playing music, but still your app needs to be running (in the background). Android has something called Services for this, which makes it a bit easier.
I would like to create a SDK for mobile developers to embed my solution, but instead of writing it in Swift and Java, I would like to use Xamarin to write it once and then export to the selected target.
I'm not sure if it possible, I saw this answer : Is it possible to embed xamarin part into an existing native app?
but it was sometime ago so I wonder if things have changed or if there is a workaround, like writing a small native part just to create the bindings and export this as the sdk then...
AFAIK nothing has changed, still not possible.
I have a small 2D game engine written in C#, using DirectX. Is it possible to somehow run it in a browser as a plugin? Like for example Flash and others, where you go to a site with a game and it will ask you to install a certain plugin and then you can play the game in the browser, with mouse and keyboard input.
I have searched around for hours and I still don't know what I'm looking for. I have so far primarily focused on Internet Explorer, but there are plugins, addons, extensions, etc I don't know what I need really.
Yes I think it is possible.
For example, I have an HTML page which includes an element like this:
<object id="simpleControl1"
classid="http:RenderTextProject5.dll#RenderTextProject.ScrollableControl"
height="300"
width="300">
</object>
The 'classid' attribute value has the following meaning/syntax:
RenderTextProject5.dll is the filename of a compiled .NET assembly
RenderTextProject.ScrollableControl is the qualified name (namespace plus classname) of a class which subclasses System.Windows.Forms.Control
I can then see the control being rendered in the browser.
I'm using IE (IE8, but it used to work with IE6 too), and I have the .NET framework installed on my machine (but I think I needn't have the RenderTextProject5 assembly installed on the client machine).
There may be some other caveats too (e.g. I needed to run in the Intranet security zone).
See Return of the Rich Client: Code Access Security and Distribution Features in .NET Enhance Client-Side Apps.
Look for Silverlight.. It is maybe not exactly what you need but it is a browser plugin capable of running C# code ;)
There is a relatively new plugin called Unity. It is a bit more complex, as it is a dev/3D authoring environment on its own, but uses C# as its language as far as I know. However I don't know if pure 2D programming is possible (well, may be worked around using ortho 3d?).
The basic version is free to download recently, maybe worth a check.
It is possible to run C# applications in a web browser without using plugins. For example, C# applications can be compiled into JavaScript applications using JSIL.
