I want to display a video player and contols it in react native but that video player is in kotlin language, So how can control and display android native activity and controls it in react native ?
Yes you can make a Video Player from native side, and expose via NativeModules and pass some props.
Ive done it a long time back and its possible, you can pass URL, height width etc . but im not sure about how well can you fetch the controls etc.

I want to make an autoclicker app that can also take screenshots and recognize the location of a specific image (of course it will run over another app). can i do it with either xamarin or react native? if yes i would really appreciate it if you suggest me some tutorials or code examples.
I am new to react native. my question is. what is smart way to test your react native screen UI on different mobile size screen with only one mobile. please help thanks
I want to call an external app that is already installed in the mobile using a deep link and display that on 80% of the screen inside my app. Is it possible to do this in react-native?
You have to use this module for opening other apps but it will open up for the whole screen with deep linking, The Reason is that Other apps are also native apps and have their separate implementation.
You can trigger different apps but opening for 80% of the screen is not possible because this is not a Webview where you can control the height.
Simple as that, You cannot open one app in '20%' of the screen and other for '80%' of the screen.

Currently, if I add a .gif to app.json, it does not work
"splash": {
"image": "./assets/splash.gif"
}
Edit: It looks like, they are currently working on it, here: (https://expo.canny.io/feature-requests/p/improved-splash-screen-api).
I see you are trying to use gif for the splash screen. Well I have a bad news. Splash screen API of native platform (iOS & Android) doesn't support gif, infact they only support 'png' images.
But, the good news is there is a work around.
We had a similar requirement in our project so we created our custom AppLoading (Provided by Expo) component which has a face of our gif image and in the background it works similar to AppLoading i.e. fetch data and caching. We used a static png image for default splash screen and the transition between static image to gif worked for us.
This is the simplest way but has a drawback that between the static splash screen and animated there is white screen visible for a short duration of time.
It happens due to the fact that your javascript bundle is being downloaded in the background and until and unless your entire JS doesn't load you will see a white screen.
To overcome this you need to detach your expo app as we will be doing some native changes.
Install and follow the instruction in this module.
Benefit of this module is that it exposes the 'hide' function in the javascript.
Basic flow of App.
App loading start => Static splash screen visible
Screen is visible till our javascript bundle is not loaded
Bundle loads => call hide function exposed by modules on ComponentDidMount of SplashScreen component
Static Splash screen hides => Animated splash screen is visible with background task working (caching and API call)
Further App Flow
If you're talking about the launch screen and you're not using create-react-native-app you'll have to edit the native launch screen per platform to use your animation.
If you're using create-react-native-app with Expo then you could look at the Splash Screen API.
Expo since version 29 supports animated SVG and GIF. It also provides an API to generate your own splash screens without AppLoading.
Please check: https://docs.expo.io/versions/v29.0.0/sdk/splash-screen#example-without-apploading
Expo team has completed: "Improved Splash Screen API" ticket. So now, you can do it as explained in their docs: https://docs.expo.io/versions/v29.0.0/sdk/splash-screen/!
