Is it possible to register NFC events with Meteor.js framework?
What would be the minimal example?
We chose Meteor.js for it's suitability with lean development, we understand that there are more efficient tools for mobile development.
See the Cordova plugin com.chariotsolutions.nfc.plugin which is documented as handling NFC for android and windows phone.
With the cordova plugin, it appears to be (meteor standard) simple through the user of the NFC object:
nfc.addNdefListener(callback, [onSuccess], [onFailure]);
NDEF events are fired when the NDEF tag is read.

I'm currently developing a little project, i've bought a "smart lock" with works with Bluetooth and uses an open platform called TTLock. The resources are here: https://open.ttlock.com/doc/userGuide
The idea is to create my own App to control this "smart lock" using the methods created by TTLock.
The web page gives SDK resources for Android and IOS, but i want to program my App in Xamarin.Forms. My question is, can I "add" the Android SDK and the IOS SDK to my Xamarin.Forms solution and work with that methods, or i have to program first in Android Studio and later in an IOS IDE?
Thank you so much for your time and your responses. I'm learning about programming APPs on IDE, so all knowledge will be appreciated.
My question is, can I "add" the Android SDK and the IOS SDK to my Xamarin.Forms solution and work with that methods,
The answer of the first question is Yes. You could refer to Binding a .JAR document to use it in Android, and refer to Binding iOS Libraries document to use it in iOS.
or i have to program first in Android Studio and later in an IOS IDE?
The second question is depends on you. You will not need to use native IDE to do that.
For Android, there are two ways to get the native library:
Using Android Studio to download it
Going to Source repository website to download it
First method, I think you already know that, from the document you will find the sample steps:
The Second method, the shared document is chineses language. Therefore, you could find the source repository website here: https://maven.aliyun.com/mvn/search, and search by typing tongtonglock you will see the navtive libraries as follows. Then you can pick one to download.
For iOS, you could refer to its sample link to get the framework.
I'm looking for a way to have an application just process voice commands every time I say a specific phrase. The behavior should be similar to Cortana, Alexa or others. The application will be deployed on a hands-free device, but the Speech device SDK cannot be used, because it runs solely on a PC.
Is there an addition to the Speech SDK with a custom wake word yet?
MS speech recognition uses RESTful APIs to cloud services. You can use them from any device.
You can use speech-to-text and voice command services on Android or iOS. https://azure.microsoft.com/en-us/services/cognitive-services/speech/?v=18.05: Examples exist for both Java and Objective-C.
I think you also want to check out the preview of speaker recognition.
https://learn.microsoft.com/en-us/azure/cognitive-services/speaker-recognition/home
Does this help?
Looks like you would need to go to a specific site to set a wake work as it's still in preview mode. That will generate some files that you'd download for the SDK.
There's more in this documentation page.
since I am new in the world of developing apps for watches, and the fact that it exists for smartphones the following frameworks:
Xamarin
PhoneGap
appcelerator
kony
Cordova
...
I wonder if there exists for watches apps similar frameworks? So that you code once but run overall.
Thanks
Edit 1:
At this day (12.05.2015) regarding to the answer of a nativescript maintainer here. I will go with nativescript to start writing app for wearables.
Cordova/PhoneGap apps don't work directly on the wearable devices/watches. Cordova/PhoneGap is basically a javascript API which can run on WebKit/WebView on all the mobile OS's. But the Android Watch and Apple Watch doesn't support WebKit and so the apps developed with Cordova don't work directly on Watch devices. But if want to extend some of the features from the existing Cordova app to the wearable app, you need to create the extension app in native language and the extension should be able to communicate with the paired app on the mobile device. The extension on the Watch will have only UI and the bussiness logic etc runs on the Cordova app on the mobile. It is possible to establish communication between these apps which will drive the display on the watch devices.
I am not sure about the other frameworks you listed above on how much they support wearable devices.
As #kiran and #NRimer have mentioned, these cross platform frameworks are relying on the WebKit/WebView which is the almost universal layer supported on every mobile device. They dont run directly on the device, but device runs WebKit platform that runs these cross platform apps. So comparing the capabilities of the native app with cross platform app, native app is bigger, because it can have a hands on device hardware related features. The thing particular to the smart watches is that they mostly rely on other smart phone device, and it uses it's communication protocols, that are hardware specific, and WebKit doesnt have its hands on it.
It depends on what you're looking to do with the framework. Watch apps build off data provided by their containing app. For example if you want to provide custom notifications on the watch, the app (or server for remote notifications) constructs them. When your watch app needs information, it makes a request to the containing app. Lets say you have a group of apps that you want to provide the same notifications or functions on each of their watch apps, you could make a framework that handles these functions for the containing app. As for the watch portion, think of it as more of a display of information provided. Unfortunately i dont think there's a way to generate frameworks for watch apps yet. If you're looking to have a lot of code within the watch app this might be more difficult but for simple display of information you should be alright.
First of all am new to PPAPI plugin development. Earlier i have been using NPAPI plugin to perform certain functionality which in turn uses windows APIs.Now since NPAPI is obsolete, i am trying PPAPI. My question is can i link windows APIs to PPAPI? Is it possible ?
As Bennet mentioned, it is not possible to make calls to the Windows API. If this is necessary for your application, try making a Chrome Extension and using Native Messaging instead.
From the link:
Extensions can exchange messages with native applications. Native
applications that support this feature must register a native
messaging host that knows how to communicate with the extension.
Chrome starts the host in a separate process and communicates with it
using standard input and standard output streams.
It is not possible to call Windows functions. If it were, then it would be trivial to escape the NaCl security sandbox.
My team is in the planning phase of a multiplatform mobile app. We're considering Adobe Air/Flex or Appcelerator Titanium instead of native development, but will eventually be needing to use an external API that is ported to iOS and Android. **(one that harnesses the device's camera)
The idea would be to use platform detection and overloaded classes to determine which platform version of the API to import. Is something like this possible in either Adobe or Appcelerator? If so, would the native Objective-C or Java need to somehow be wrapped in Actionscript (if Adobe) or JavaScript (if Titanium)?
Any advice would be fantastic.
A near-term (no dates yet) release of Mobile Air will include native extensions. The native code will be written in the platforms' native languages. ActionScript interfaces will exist to interact with these extensions, the specifications for which have not yet been released.

Titanium is 100% native code.
How Does Appcelerator Titanium Mobile Work?
