Can I use GPS in J2me enabled phones?
I am curious to know whether one can use GPS in J2ME enabled phone or can create an application based on GPS?
JSR 179 Location API for J2ME is intended to support creation of applications based on GPS, see JSR 179 specification page, section 2.5:
...this API shall work with most positioning methods, such as GPS...
If you are interested in more details, below tutorials make for a good start:
Develop a location-based service application using JSR 179

In Acumatica framework for mobile applications is it possible to work with Mobile camera and bar code scanning? Or at least with camera? Is it possible to add some C# code, which will be running inside of Acumatica mobile application?
Some ideas can be found in I400 and the Help docs - Configuring attachments in Mobile and Enhancements taken from Camera:

For the C# code, I am wondering if adding a View on Note or UploadFile/UploadFileDoc for given FileID/NoteID:
public PXSelect<UploadFile, Where<UploadFile.noteId,
Equal<Current<YourDAC.noteId>>>> Attachments;
and subscribing to UploadFile_RowPersisting or other event.
I am working on creating a Windows 10 Universal app. My goal is to have the app run in the background and periodically display a status notification to the user.
I've seen a few articles that talk about creating a background task within the app (https://msdn.microsoft.com/en-us/windows/uwp/launch-resume/run-a-background-task-on-a-timer-), is this the best design pattern I can follow? I'm fairly new to Windows Universal apps and any recommendations on how to do this would be appreciated.
Look at the IBackgroundTask docs. In addition, you can easily implement notifications via the OS with Adaptive Toasts
Since the story around notifications can get complex depending on how you want to control UX, don't be afraid to research building an RT component if you can't find a UWP API that meets your needs. For instance, you can package an RT component with your UWP app that calls into native C++ libraries or more low-level Windows APIs to curate the notification experience for your user.
I need to build a web based application that can list available ssid in the area.
From my understanding, these probably can do what i want
Java applet
Adobe Flash
However, Im not sure whether these can do or not
HTML5/JavaScript
Java Web Start
I'm a .NET developer and I'm not familiar with these web technologies.
Are there any other method to get a list of SSID that i have not mentioned?
Thanks.
You'll never be able to list available SSID's with HTML5, Javascript, or any other strictly web-based technology. That's a very low-level task and won't be natively possible in any browser for security reasons. That being said, you may be able to draw on some technology like Java Applets, ActiveX, or even Silverlight 5 if I remember correctly. I don't know your project requirements, but you're better off creating a native application for this type of feature. If this application is being used by/sold to the general public, you're setting yourself up for a lot of headache by going with Applets/ActiveX/etc.
I understand that with MonoTouch and MonoDroid that you develop against the native UI layer, which is a good thing. However, I was wondering if there were any cross platform Mono API layers for features such as camera, location, storage, notifications etc... ?
PhoneGap supplies a JavaScript a abstraction layer that does just this. Is there a Mono equivalent?
There is an official monomobile api project from xamarin - that provides camera, contacts and gps abstractions, plus there are discussions (but not firm roadmaps) about extending this further. See http://blog.xamarin.com/2011/11/22/introducing-the-xamarin-mobile-api/ for an intro
Beyond that:
some api's exist cross platform from the start - eg isolated storage can be used on all platforms.
I've seen a few other GitHub projects started - eg chrisntr's mono extensions
I've written a few abstractions (e.g. File, gps, camera) in http://GitHub.com/slodge/mvvmcross
I recently came across MonoDroid.Dialog. I have yet to use it, but if it is as easy as MonoTouch.Dialog to do tables then I will be very happy with it.
I need some links to record both microphone and audio in all the applications. I'm developing a audio recorder feature for an application.
I tried intercepting some APIs like IDirectSound and Wave API but I'm missing something since some applications are recorder and some others aren't.
Can someone send me a clue around this?
Best Regards.
In my compary we've developed an Audio Recorder SDK because it's very difficult to make all the hooks you need to intercept all the applications. You should hook MCI Wave API calls, IDirectSound interface and the new IAudioClient interface, part of the Windows Vista / Windows 7 Core Audio engine.
Our SDK supports Skype 4.x and 5.x, G-Talk and Msn. We've tested with other applications and it's working but we don't support them.
Additionally, we bring some UI features such as handling button clicks and get windows text using the SDK.
I hope this information can help you.
