I would like to include a feature in my app, where you can scan a certain picture and the app would recognise this image. Just like the image recognition feature in Viro: https://docs.viromedia.com/docs/ar-image-recognition . So I would set a certain image and it only needs to recognise this image.
I'm working with expo react native.
Does anybody have and idea how I might build this feature?
Thanks 😊
You can possibly just make it call a python service on the backend and pass it the image and get back the result for it.
If you want to go serverless, you can even get a premade AWS lamda function, which you can call and pass it the image, and it'll do the processing for you.
In the end, it's better if you do this kind of processing on the server side, your app could get locked up because image processing can take time and you don't want that to happen on a mobile app.

I'm using the package Agora Video SDK for Unity and I have followed these two tutorials:

Up to here, it is working fine. The problem is that instead os sharing my screen, I want to send a texture. To do so, I'm loading a png picture and trying to set it to the mTexture you find in the second link. It seems to be working on my computer, but it is like it doesn't arrive to the target computer.
How can I send a texture properly?
Thanks
did you copy every line of the code from the example as is? You may not want to do the ReadPixel part since this reads the screen. You may just read the raw data from your input texture and send it with the PushVideoFrame every update.
I have an app in React Native, that uses the bluetooth connection to read data from external devices.
I need a way to continue to read this data in background when, for example, the user starts a reading session and put the app in background.
What should I use to do this?
My code is divided in two parts:
Scan and Connect
Reading Data from external devices.
You need a background service for this. The following link for Android will help you.
github => react-native-foreground-service
If you want, you can do it yourself as described on the RN official site. But you'll have to write Java code for it.
React Native => Native Module
Can anyone tell me why when I use my app, every boot up has a lag when loading my images and vector font icons? It probably only lags for a second, but it looks really bad.
It can't be the sizes of them because even the vector icons have about a second lag. Is there any way to prevent this
Would this have anything to do with it being connected to Expo?
You can resolve this by caching your assets while the app loading screen is still up: https://docs.expo.io/versions/latest/guides/preloading-and-caching-assets.html
Nevermind I found out it's an Expo thing. They strip all of the local images and put it in their cdn before building the app. Take note if you have an app in production using Expo
I am new in Xcode and IOS development.
i have designed and finished my app and i connected with Parse for push notification and core data.
the problem is what i didn't understand is: if in future i want to change the background of my app or add new event or to change the palace of button my app, how can i do that? i have to rebuild and submit it again or there is any way to do by online a website like parse?
i couldn't find the answer any where, help please...
Thanks ,
If you had designed your app to load the background data from Parse, then you could just put the new background on Parse and your app would load it. There is no need to submit a new app to do that. If you did it this way, you'd want to have a default background in the case when the network is not available.
You can't add new code to your application with this method (that is not allowed), but you can add data such as images, text, etc. The key point here is that you have to design your app from the start to work this way, then it is simply a matter of putting the new data on Parse where your app can find it.
Expanding on #vacawama's very good answer:
For this version you are out of luck, since it sounds like you did not design it to use a background that is loaded from your Parse server.
What you need to do is to code an update to your app that has these new abilities, and submit that to the app store. Once that version is approved then you should be able to change the background from the server.
