is NFC Host-Based Card Emulation possible in dart/flutter? - android

I am making a flutter app that uses NFC to communicate with other android mobiles, I already found projects that implement this, however, they are made in kotlin or java this, is there a way to implement this in dart/flutter?
packages such as nfc_emulator do not work for me I have tried their example and nothing happens once I read it from another device. i would really appreciate any help in this

java applet to android workflow

I have built an interactive taxonomic key and the output is a java applet. I want to covert it onto an app that can be used locally ie on phone for example with no connection to the internet (its important as people on project are working in remote locations).
My question is can I edit the java applet in Android studio? Willing to learn just want to know what the best approach is. later would need to work on it being available on IOS devices too.
Thanks, Amanda
Java applets and Android apps have nothing in common with each other, other than language. The UI and input frameworks are totally different. You could share some of the logic of the app if you put it into a jar file, but you won't be able to share anything else. And Java doesn't run on iOS, so that's totally out.
Also, not sure why you tagged this javascript. Java and javascript are totally different languages. A Java applet has nothing to do with javascript.

Does an equivalent of Wi-Fi Direct/Wi-Fi P2P exist for Phonegap/Cordova?

I'm building an Android application to allow communication between two devices in a limited range but I can't find an equivalent plugin to the native Android Wi-Fi peer-to-peer for Phonegap/Cordova.
Any suggestion ? May another service (such as the Google's WebRTC) do the trick ? Is going native the solution ?
I am having the same problem but there is a plugin called "thali" which I haven't tested it yet but here is the link anyway if you want to give it ago.
let us know how you getting on

Android app development on PowerBuilder

Anyone know if its possible to develop android apps with PowerBuilder.
Haven't found much regarding this on Google, which might mean that it isn't, but still want to hear the opinion of ppl at stackoverflow.
thanks in advance
right now I think the only possibility is Appeon Mobile for PowerBuilder. This is a beta version and it is supporting iOS right now, but in several months it will be capable for building native android and Windows Phone app too.

I hardly waiting it also :)

One other possible solution I've considered but it is NOT a trivial solution. Look at IIS modules and handlers in the MSDN. Basically you can write a handler in PB.NET that will be used in IIS to create HTML5 that will run in just about any browser including mobile.
You then could assign a certain file type (e.g .powerbuilder ) which will be processed by your custom handler that was written in PB.NET.
Might be a good open source project.

Accessible Android Air application for the blind. Using Androids TalkBack

I'm looking for some help on how to make an Air application accessible to the blind. Its required that I use the screen reader functionality that comes built into android called TalkBack.
After researching I have failed to find anything useful. I did find out that you can check if the device has accessibility aids using "Capabilities.hasAccessibility()" however that returns False even when the device does have aids and they are turned on (Accessibility.active is also set to False when TalkBack is active). I also found out that you could give a Display object AccessibilityProperties such as a name and a description that I assumed the screen reader would use. However, It doesn't work. I have also used the Accessibility.updateProperties() after adding the properties and still no luck.
I also tried adding the permissions to the manifest for READ_PHONE_STATE (although I'm not really sure if that's what its meant for) but again no joy.
I'm using Actionscript 3 only. Not flex.
As best I can tell, Adobe has decided to ignore the disabled community when it comes to mobile apps built with Air. There does not appear to be any way to implement accessibility for such applications.
I would love to be wrong about this, but as it stands now, I am pretty certain that this is the case.
From searching the past few days and doing a bunch of tests it seems that the accessibility features you can build into AIR applications are only going to work in browser-based apps. Any kind of stand-alone style app (.app/.dmg/.exe/.air) form of distribution doesn't seem to work with any of the accessibility tools we have tested. We tested Window-Eyes and the built in Narrator in Windows 7. I have been unable to find any Adobe documentation to confirm this, but it seems like a huge oversight for them not to mention it in any documents.

android bluetooth

Can someone explain to me the concept behind using bluetooth?
My project in my studies is to make an android app using bluetooth, SQLLIGHT and google app
the app itself is a very easy one but I just dont get the tools I need to use :
How does the bluetooth works? Is there a simple example?
the concept behind android GUI (I already made one but I think I am not fully understood his power)?
note : I am using v 2.1
For learning bluetooth on android I guess you should dig into: http://developer.android.com/guide/topics/wireless/bluetooth.html
Should be simple.
Before you learn to program Bluetooth with API on a given platform, you need to read up a few basics first to understand the technology first. There are plenty of resource materials on internet for learning. If you prefer a book, you can try http://www.amazon.com/Bluetooth-Operation-Use-Robert-Morrow/dp/007138779X
