I've found this awesome tool http://www.chargeanywheredirect.com/bluetooth-credit-card-reader-printer.html, but im not sure if i can use it to make my own mobile app cuz they dont have public api.
If anyone know this device better or know anyone what does the same funcions (Read card and print). Please help me thanks!.
Star Micronics has a printing SDK for Android and iOS.. Card reading is one of the functions. You can download it here: http://www.starmicronics.com/support/SDKDocumentation.aspx.

Hi i want to write an application in react-native that people in same place can join each other and play a game on bluetooth connection.
The first question is if it is possible with react native?
And second is which documentation can help me ?
Thanks
I dont see why not, i have used Ionic wich uses Cordova (non native) to create bluetooth connections without problem, bluetooth is a basic feature of phones.
Take a look at this library it may help you or give you a good point of start: https://github.com/Polidea/react-native-ble-plx
I am trying to create a mobile P2P game with network library written in c (enet/libuv).
I have read in some forum that there is risk of blocked port by the router and I need to do something called port-forwarding.
Most of the topic related are for console games and I'm trying to do mobile game, which theoretically should be the same.
Sorry for my noob question but, will it be a big issue for my game and how can I fix this problem (without using any third-party help) ?
Many thanks for the help.
Does anyone have an idea to implementing lock screen that uses fingerprint to unlock the screen on a codenameone app. Any ideas at all will be welcomed. Majority of ideas i have seen are basically cheat concepts that does not implement the concept. You ideas, resources, links etc are welcomed even if it requires a 3rd party service butt I think java native code may be able to do this, i just dont have a clear idea yet.
Global lock screen can't be implemented in Codename One since its very specific to Android and has no portable alternative. You might as well just write a native app.
You will need to write a native interface to access the fingerprint reader hardware:

Using the native touch ID should be pretty strait forward e.g.: http://www.devfright.com/touch-id-tutorial-objective-c/
I am currently messing around a bit with libvlc on android using the NDK.
Well, I understand how to use native C code in an android app.
Now I would like to use the libvlc library to make a simple player which would read data from a socket.
Is it possible to use libvlc at that level? The problem I see is when it comes to set a window handler for libvlc to draw the image on.
Has anyone experienced with this that could give me some feedback?
Thank you.

My class and I are trying to make a robot, we need to be able to take a picture using a kinect in Labview. We know how to get a skeleton from the kinect, but we can't figure out how to take a picture/video. Is there a DLL we need to download? We can't find anything on the internet but we know it's possible to do in labview. So do we need to write any code in C? Im pretty good with C so don't restrict your answer to just labview. All relevant answers are welcome.

Personally, I have no experience with this, but a quick "LabVIEW Kinect" search on Google turns up any number of results, including some which show video (example). Based on the videos and images I see there, it looks like they're using the IMAQ control to show the video, so I'm assuming you're going to need the vision toolkit for that. If you have an academic license, you might already have that, but even if not, you could try asking your local NI office for one, as they generally tend to support schools.
I would go on ni.com and search for LabVIEW Kinect. There are links over there like this:
