I want to ask something regarding my final year project. I am developing a medication reminder and storing these data on the image below on async storage. So basically I want to run a notification in the background and notify the user based on the given time on the image below. So I am figuring out what libraries I should use to achieve this. Are there any libraries that I can use in order to accomplish this? Asking for suggestions.

first time asking here as i am looking for some guidance before i start coding.
I have been developing websites mostly in PHP/MySQL/Jquery for years. As I was requested to port a website to an app, I selected React Native in order not to learn 2 different languages for IOS-Android.
I subscribed to some react native lessons, as I found it very clear and fun to follow, and it indeed is.
But here I am finding that to replicate the website is a truly difficult task for me. A temporary version exists at https://app.thallo.care/app.php?language=en (view on mobile if you like). There are many fixed positioned things and floating menus that i cannot easily program on react native.
I tried webview, it works wonderfully, but i am not positive i will be able to implement notifications the way i want to, or custom app styling with inject javascript i am unsure it will work.
The only app difference comparing to the desktop version, is that the user will receive notifications. The website will have a calendar where he will add events, and i need to send notifications to the user device on the event datetime that he has set.
Now the question... Should i use webview and manage notifications on a third party app like amazon SNS or anything else, will i get per-user notifications on events with webview? (I dont need to open a specific page on the app, but it would be nice). Or should i insist on react native coding and try to replicate as much as possible, to be able to have proper notifications? Reminder - the events won't be sent by the app. they are stored in MySQL and should be stored on some other service as well (that i dont know of yet). I don't know also if the webview can handle the website programmed login-logout with $_SESSION php parameters.
I would really appreciate some guidance.
Thanks in advance,
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 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
Problem:
I am creating react native app. In there I want to create something like this. There I want to create a chat when a user speaks the start and destination to the app it should speak back to the user about the road. I searched a lot on the Internet but I was unable to find any good way to create a live chat with the app in order to get the start and destination from the user. It means I want something like this.when user say hi to the app it should also say Hi. Then It should say give your starting point and after that app should ask for the destination. Can Someone help me to create this small live chat with my app in react native?. Thank you very much.
you can convert the text to speech using save react-native-tts and convert the speech to text react-native-voice.
for the chat react-native-gifted-chat you can use this
The best way to do this is using npm package react-simple-chatbot also adding Speech-to-Text(STT) for voice input and Text-to-speech(TTS) for voice output.
Check the NPM packages :
STT - https://www.npmjs.com/package/react-native-speech-to-text
TTS - https://www.npmjs.com/package/react-native-tts
Or Both combined here https://github.com/pwcremin/react-native-watson
Hope it helps you..!

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.
