I am trying to develop a React Native based application that collects sensor data from Movesense Sensor.
One of the guides I am referencing to is https://github.com/tugberka/react-native-mds this repo. (as suggested in the development document)
I was just wondering if this repo is compatible with the latest SDK version and will there be example code coming?
Have you checked out the gatt sensordata app example from Movesense bitbucket (https://bitbucket.org/suunto/movesense-device-lib/src/master/samples/gatt_sensordata_app/)? By using this example firmware you could create a React Native app without the need to use MDS libraries.
In web_client/index.html you can see javascript example how to parse data if you want to use this firmware.

I am working on an application where main screen has a live camera opened automatically.
Here I need faces to be detected.
Am getting confused about how to integrate ML kit.
Do I have to signup with firebase????
I tried working with google ml kit but got too many errors.
There are two separate ML libraries now - Firebase ML and ML Kit. Firebase ML runs on the cloud, and you need to use Firebase for it. You can find the documentation here.
ML Kit, however, runs entirely on the user's device, and it does not require you to use Firebase, unless you want to use custom models.
The easiest way to integrate it into your flutter app would be to use the google_ml_kit library, which provides modules for different purposes. For face recognition, you can use google_mlkit_face_detection.
I would like to add functionality to my Ionic based application to check the respective app store for a newer version, and if present, prompt the user to download once (not repeatedly- they should be able to skip and not be nagged). Similar to Siren, but for Ionic and both Google Play and Apple App Store. I see this similar request for native apps and AppStore and this similar request for Play Store, but nothing specific to Ionic. I feel like I could stitch it together using App Version and ajax calls listed from those requests, but that there has to be other people who have done this already and have existing Cordova/Capacitor plugins for this. Also that there may be nuance that a naive solution could fail (ie ajax call fails, app stores change API, newer version is not supported on device, etc).
Is there an existing plugin or code that will implement the behavior described above?
You can use Market plugin in addition to the App version plugin..
I haven't come across a solution which directly checks the app store, instead i have to maintain the app version in my server db and check it at app start.
Here is the flow that can be used..
App Launches
Checks the current app version using APP VERSION plugin
Calls an API endpoint to my server to compare for the deployed app store version (which is maintained in the db)
If the app version is outdated, use the MARKET plugin to take the user to the app store.
A Capacitor alternative to the market plugin is there, but didn't test it out.
Follow Capacitor plugins proposals, for an upcoming solution.
When an external component such as a Camera or File picker is needed, the Flutter for Android Developers documentation (currently in the works) states that we would have to build a native platform integration.
I currently have a device that has a built-in barcode reader with a manufacturer-provided Android API. So, for that I would need to pursue this native platform integration method - or even for playing videos or using the camera for that matter I would think.
Is there an example repo that demonstrates how a well-integrated app should be? ..a project that integrated ExoPlayer for example?
You can use platform channels to call native APIs that aren't exposed by the Flutter platform.
There is an example in the Writing custom platform-specific code docs:
The full, runnable source-code for this example is available in /examples/platform_channel/ for Android with Java and iOS with Objective-C.
If you want to make your code reusable by others, you can publish it as a package, but this is optional. There is a repo of plugins maintained by the Flutter team that you can use for inspiration.
I have read some docs and i do not really understand what are the differences between react and ionic frameworks.
Is one of them made from the other ?
I have to store local data. I suppose one of them is just web and javascript so data is only stored on server ? Or is it possible to do local storage with both of them.
Is it possible to host the app on a web server without having a "real" app ?
Thanks
Hi I think that you are a little bit confused. I hope this clarify your doubts:
Ionic framework is a set of tools for create Hybrid apps using html/css and javascript, It is build using apache cordova and Angular 1. In the other hand you have React a library for build rich UX(User experience) web apps.
Ionic is not build on react. They are different purpose tools but you can use that together (Using IONIC 2).
In both cases you can use local storage, but if you want to store data in servers you have to build your own backend to provide data to the app They are front end oriented frameworks(no server side)
You can put Ionic code on a server it is simple JavaScript and HTML but this is not the purpose of the framework and if you do it, you loose the native apis of the device. In the case of React it is just a library and you can use it in an existing project using HTML and Javascript or build your app entirely with it.
You have a long road ahead, hope this help you.
Ionic is an HTML5 mobile app development framework targeted at building hybrid mobile apps. They are essentially small websites running in a browser shell in an app that have access to the native platform layer.
React Native is the next generation of React – a JavaScript code library developed by Facebook and Instagram, which was released on Github in 2013. React Native lets you build mobile apps using only JavaScript.
They have their own way of functioning, below are few points on their differences:
Ionic is a regular web app, written using HTML, CSS, and JavaScript, but it runs in a webview embedded in a native app instead of in a stand-alone mobile browser
React Native has a completely different architecture: instead of writing your UI using web technologies, it uses the React component model to render to native views.
Ionic is a Cordova based app that wrap current web app into a mobile application. It uses the android existing web view to render the app so the file size is quite small
Meanwhile react native create bridge between JavaScript and native component.
When it comes to memory usage, Ionic framework uses more than react native apps
The Ionic app is slower at loading videos because it needs to download from other server, while in react native, it caches the tiles so it loads faster.
When it comes to integration, react native can use every client based JavaScript modules from npm (node package manager) whereas Ionic uses only the Cordova-based code.
Ionic is a framework that creates an idea of writing code only once
React native is not a write once and run anywhere framework, but is popularly touted as a “learn once, write anywhere” framework
Ionic Framework app needs to use device features and APIs through Apache Cordova plugins.
With react native you can access any device component or API
Based on the points above, you can see the difference in their functionalities, so if you want to go for something that creates performant iOS and Android apps that feel at home on their respective platforms ten you can opt for React Native.
And, if you are targeted at building hybrid mobile apps, Ionic is the best choice!
Do you think that if I'll build my own custom analytic tool (Flurry, Pinchmedia) and I'll host that on the same server where I have my data source for the application, will Apple consider this as a thirdparty analytic tool or not? ... Problem is that Flurry and Pinch are being banned from Appstore by the newest T&C ... than I thought that I'll build an open source library that will allow anyone to have their own analytic installed on their server ...
Thanks,
Ondrej

What you describe would seem to comply with Apple's new terms. It's what I call 1st-party collection of device data. Or Apple could approve your use 3rd-party analytics, which is more likely if your analytics service isn't using those data to serve ads or selling data to someone else.
But why build it yourself? Localytics announced its Enterprise analytics service last week, which includes 1st-party data collection: http://www.localytics.com/blog. Localytics client libraries for iPhone (and Android and BlackBerry) are already open source.
