I am considering a project to add peak and off peak time configuration to the aosp email app. I have zero android or java coding experience and my general coding experience is limited to some pretty simple php. However, this is a feature I greatly desire, and my searching tells me others do as well.
I was wondering if anyone could tell me if it is feasible. Any advice on where to start?

Hello all,
This post is in regard to the Google Android Challenge put out by Google to create/develop new software for the Google Android shell. If you haven't had a chance to read about it, it's basically a new OS created by Google to run on any type of PDAesque cellular phone. The challenge issued is then to develop new software for this OS (written in Java) so that when it is released it will have software available for it.
My question to all of you is what software would you like to see developed for this new OS? The reason I am asking for ideas is because I am a CS undergraduate student working in a research group to create one of these programs. Ergo, I figured asking you guys what you'd like to see created would be the best way to get ideas that will make sense and benefit the community.
Any ideas you submit here may be used in the creation of new software--if you require idea copyrights that can be worked out.
Thank you all in advance,
Jake

Hello Jake,
We'll I'm a Java programmer too, not thinking of entering the challenge though. Had a quick look at the SDK for Android and it does'nt seem like pure java, more like a hybrid of C and Java does'nt it?
Since I have'nt had a thorough look at it, I'd like to ask you a few questions regarding the freedom to program on the platform.
Since it does'nt use the "normal" JVM but googles Davlik where theres no byte code but script code, does it allow better interaction with the hardware, and is it faster? Also can you implement equallizers and other effects in a media based application, which of course was not possible on J2ME. I was thinking on a All-round mediaplayer for Android, something like Rockbox which maybe found at www.rockbox.org which is a linux based program used on iPods etc.. but has been ported to Linux based EZX phones.

I have barely developed anything since the BASIC days on the C64 and Amiga, and now feel inspired to create some financial applications for the Australian market - such as superannuation projections.
How hard is it to develop? A few standard calculations like you would see on a spreadsheet would work, with some graphing.
Most financial applications I have found are pretty basic and don't account for inflation in rising wages and fees, etc.
I believe I could attract at least a dollar for a well developed application for superannuation alone.
I have installed the Android 2.2 SDK and have no idea where to start. I presume this is some sort of emulated Android device I can test my applications on.
Are there any tutorials on how to get started? What's the development language?
All I need to do is create a simple text interface to input a few parameters to run some complex financial calculations on the back end.
A really sophisticated application would pull live interest rates or other data and enter that in.
Start with this:
developer.android. com/resources/tutorials/ hello-world.html
(take away the spaces, I cant post links yet )
These are all great tutorials that will walk you through the basic processes and applications/layouts. The only issue you will have is when/if you decide to go through the "Tabs View" tutorial, there are a lot of errors in the code, and I have no idea why no one have changed it, but you can PM me for the correct version.
If you want some basics on Java, just do a google search, there are a lot of great tutorials out there for beginning Java. I recommend doing this first, just so you have a good understanding of Java(which is the development language), it will *REALLY* help out. You can incorporate other languages, but for the time being, stick with Java.
Yes, the SDK comes with an emulator so that you can test your programs without having to install them on a real device. In addition to what Jimmy said (and I can't stres highly enough that you should start with the Android Developer's website and tutorials), you can go to Stack Overflow which is a programming Q&A website. People there are generally very helpful, as long as you've shown you've actually put some effort into solving your problem before you posted your question.
Fair enough... So it's basically about learning to programme for Java? How hard would it be, realistically, for someone with no application development experience?
You need a basic grasp of objected oriented design & programming, along with an understanding of the Java language. When it comes to gui aspects & all communication with other apps/data on the device, you have Android, rather than the usual Java class libraries such as awt or swing.
How hard? It's doable, imo, but will depend on aptitude. Start with Java & then add in Android when you feel like more material to get your head around.
So basically getting started requires me to learn application development like on any other platform, in OO and Java. I may as well do a course or something then. Would a few weeks doing some sort of intro course help?
I'm sure an appropriate course could be very helpful. Though I'd steer clear of those short courses claiming to turn anyone into a valuable skilled programmer in only xx weeks, if only because the tutor will probably know less than you on the subject. Better one which makes credible claims regarding its introductory nature. A couple of degree level intro modules on OO or Java should be of help.
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'm working on an XMPP chat client designed for Honeycomb tablets. I've gotten pretty far on the UI and data model, but I don't have much experience working with Services. I've looked into just modding Beem or Yaxim, but both have different design goals than what I'm looking to do (I eventually want to expand it beyond just XMPP, so I'm abstracting my data model as much as possible, wheras theirs are very coupled with their services).
Right now there aren't any good chat clients that make good use of Fragments, etc. If anyone wants to help me change that, let me know. The end result will be open sourced under either the GPL or Apache. If this generates some interest I'll put what I've got on GitHub and we can discuss how to move forward from there.
I need a push start!!
i have created a circle composed of 12 concentric rings.
i want to make a live wallpaper with these rings slowly spinning in opposite directions.
i have been studying numerous web threads on how to create live wallpaper, but it just seems to me that each one assumes that the reader knows a lot more about developing in java for android using eclipse than i do.
please help me get started.
i understand the basics. i have created a couple of text based applications that i've ran on the emulator and installed on my droid x. they worked as planned!
i'd be very appreciative and willing to donate lots of time and even cash to a developer who will work with me online or offline to get this project started.
i am a veteran of 30 years software development for the VMS operating system. I've also created 2 dozen or more clock applications in lua for the windows mobile operating system. i've developed management applications for monitoring and configuring over 1200 windows 2003 servers in java, vbscript, c#, .aspx, html, perl and so forth. i'm no dummy, i can code!
i've written code in just about everything, even java, but the use of xml, manifest files, the android graphics interface has me baffled. maybe it''s just too many ways to get it done that confuses me.
anyway, i'm in need of a push start and am willing to donate to someone who will patiently get me going in the right direction.
thank you!
Although I can't give you much help, I can recommend that you look through the samples that come with the Android SDK for base source code for live wallpapers.
And also, even though the many option make it seem difficult, one you play with it for a while it gets simple.
I hope that I've helped at all. Good luck!

anybody?!
well this sure isn't the response i thought i was going to get!!!!
bump!
You'd be better off asking this is in a more generic Android/App Dev forum.
This forum is DX specific (and quite frankly, a lot of people have left the DX platform for newer phones).
