Hello, everyone! I am new here, so I apologize if this is not the appropriate section, or if this has been asked already, but I really need some help. I am working on an android app that needs to detect when you are nearby businesses (Ie, 24 hour fitness, jack in the box, gamestop...etc). I have really tried to use google for this one, but I can not word it correctly to get desired results lol. Can anyone help me? I am a complete noob when it comes to android development (I am coming from the C++/Qt world ) so examples and documentation would really help.
I would also like to ask if there is an open source area to learn from? I see a ton of good apps that would really benefit me if I could see the source, but they are all closed sourced :\.
Here's a list with a lot of open source apps: http://forum.xda-developers.com/showthread.php?t=2124002

Hi!
Im sorry if this is a dumb question but I googled some stuff about it and never found a straight YES/NO answer.
Im a student in my final year and as a semestral project I have an electronic voting system built on Java Enterprise technology with enterprise java beans (EJBs) running on Glassfish.
For my final work id like to create an app for android that could communicate with those beans on a Glassfish server and thus a people could vote by a cell phone.
My question is Is this even possible? Over the past three days ive been googling stuff concerning this matter but nothing really helped. Id really appreciate a straightforward answer because my time for choosing a final project is almost up and I dont want to end up doing something that is impossible.
Don't take it bad, but it looks like you are a student who doesn't even know what he's working with. Not that it surprises me, but I'm willing to help you.
Answer these straight questions.
1. What is an EJB?
2. Who "runs" an EJB?
3. Where does an EJB "live"?
If and when you answer these three questions you'll know what is needed for a project where "people could vote with a cellphone".
What I can tell you in the most straightforward way is that it is possible for you to have people using their android phones to vote with your Glassfish server.
Android <-> Glassfish
I am looking for the same thing - to write Android apps that communicate with session beans on an app server (i.e. Glassfish). Since I will own both ends of the app, I am looking for a simple approach (e.g. RMI) as opposed to a lot of unnecessary bru-ha-ha (e.g. why turn Java objects into SOAP, just so we can turn them back into the same Java object ... not that Android really supports SOAP).
It looks like Google, for some reason, crippled the Android's ability to communicate. About the only built-in mechanisms I've found are REST (and I don't like REST) or writing my own protocol and using servlets.
Surely, by now, someone has come up with a simple, concise, mechanism for addressing this issue ... I just can't find it.
I know how to do the WM stuff - and have some old kitchens. I used to be fairly involved in doing my own back in the Kaiser days, but never did publish them (there were always questions about whether it was REALLY kosher to do so)
Well, Android is Open Source (mostly) and so I'd like to get involved with it for the HD2. I'll publish here and maintain as well - if I come up with something useful.
Does anyone have a framework to start with on getting started? Is it best done from Windows (Win7 here) or do I need to build up a Linux box for this?
If it's already here (I looked around) please point me to it... or any online resource for that matter.
Mostly interested in cooking up NAND stuff....
(I build and write software - including kernel code in the FreeBSD realm, so I'm familiar with the "hows" - just need the correct pointers to the tools and bits I need along with a primer; I can take it from there.)
Thanks in advance!
I'm interested in the same kind of info, but it seems it's a secret kept somewhat close to the chest, and although there are tutorials aplenty for the end user, there is a clear lack of tuturials on how to make your own ROMs (be it WinMo, or Android). Either "chefs" don't want any more clutter and garbage around, or they don't think there is interest on such info...
Anyway, here is an article to get you started (little meat in the info, but dig around the wiki):

u Guy's even have take look to chef corner in this site
Hey everyone; it wouldn't let me post in the development subforum due to the fact that I just joined, but I figured my topic would be just as relevant here.
I'm a sophomore CompSci major. Java is my strong point, but I'm far from a master. I know syntax, I know how to follow what's going on in more advanced programs, but writing them is the tough part. Anyway, I would like to create my first app; something simple. I was thinking a calculator with a small clipboard on the side (hold the button to store the number displayed in the window, hit it to place that value). It would be insanely helpful for my physics class.
So a few questions for you guys:
-Is there anything I should know beforehand? Anything to be careful of?
-Can I use Eclipse? I tried with App Inventor, and it's too limited.
-How do I obtain examples of more complex apps? Can I unpackage the apk files into java classes?
-Is there a site similar to the sun library, where it lists the available classes/objects/imports?
I'm sorry if I don't know the lingo just yet (of Droid or Java). Picking this all up is a little difficult for me, but I'm trying
Thank you in advance for even taking the time to read this. I understand rookies must aggravate you guys, but from what I've seen, the community has been nothing but welcoming!
You can definitely use Android SDK with Eclipse.
This guide will help you with install and set up process
http://developer.android.com/sdk/installing.html
SDK also contains sample projects that you can use for learning.
I don't remember about unpackaging apk files, but I'm pretty sure they contain already compiled .class files, which will be of no use to you.
And here's Android's reference page:
http://developer.android.com/reference/packages.html
Also the dev guide is very useful for learning the basics:
http://developer.android.com/guide/index.html
Resources section has useful tutorials as well!
Hope that helps. Good luck with your app!
Thank you, meshdub! And all branching from the same site; sure made me look bad...but on the upside, you've introduced me to a source I will be able to use throughout my software development lifetime.
If there's any more you or anyone else could give me as far as what to expect or look out for, please let me know! I'm honestly a little intimidated by this; I'm not too familiar with forums, and I've heard how difficult app developing can be.
But this should keep me occupied for a while, and again, thank you very much
Hello! overflowers? I'm a beginner android developer and I have developed several apps that use the "basics" of android and java (for college requirements)
Now, I need to develop a new project that consists of making a web app which stores the records of all students from my college and the students will be able to check their records and other information from the college from their android phones.
I have done a lot of stuff with Android but I haven't done anything incluiding web queries, pulling info from a website to display into the device, etc etc.
So I want some advice here and/or tutorials that focus on this.
also, I have some important questions: 1. Can I pull information from the actual website from my college? If so, do I need to recieve some sort of permissions?
2. In case of not being able to pull information from the actual website from my college (for any reason whatsoever, like them not giving me permissions to do this), I could create a website that imitates its behavior, I would appreciate some tutorial or guide which could help me to achieve this.
Your help is very appreciated.
Btw, excuse if I'm breaking a rule here but something is not making sense to me.. the forum title says Q&A but when I mark this as a question it says this is not Q&A. I am aware this might be moved somewhere else but I dont know where.

I would look into hosting an sqlite3 database on a server, and access it to retrieve the data from within your app.
But the problem is, by default you cannot access an online database on Android, so you'll need to add some kind of RESTful interface, the easiest way probably being a php script which will retrieve the data from the database and return it into a JSON object for example, that you can then pull from within your app.
You'll need to expose some kind of syntax from your php script so that your app can request the data for a specific user (ie row X / column Y).
There's probably a better approach, but this is what comes to my mind.
hi all,
I have a few questions about webRTC on android. I can say I'm new about android and webRTC but I can also say I made tooo much research about webRTC on android. But still have a few questions. (some of them because of I'm new, and some of them because of I'm okey but not fully)
I'm trying to make an android app which is going to communicate between web browser (first choice is chrome) and android device directly (p2p we can say). So I made too much research and I found webRTC is good for me. Do you advise me something other or is it okey you think? (also I am going to code a plugin for chrome).
Nearly every document says 'android is not directly support webRTC'. So I need something to provide me webRTC on android. What it is? Is it native android that I have to code? Is it native (NDK) library that I have to include my project? Or is it a java lib? Or should I go for cordova/crosswalk or sth like that? I researched all but didn't find something can help me. Yeah there are documents about it but not enough..
Some of documents says, I need chromium. But why and how? They show me lots of linux terminal commands and even there is no a line java or C or C++ code. Even some terminal commands and links that they give is not working.
I read/found/tried these things as a result of my research:
Apache cordova
Crosswalk

in a nutshell I need help. Please give me your hand. Thank you. (because I'm really very helpless and tried to do my best)
Thank you.
Any idea? Any help?
