Hi all,
My name is Fabian, and I have a strong background in C. (Done a CS course in C).
I want to do an Android app for my final project(nothing too fancy or complicated but I have to at least have some interface ) and I'm a little stuck with how to proceed from here.
I watched the Java essential course on Lynda and I did understand a little the difference between C in Java, however I don't know how to proceed from here to actual Android development.
If anyone can recommend me finding a crash course, a book or any other resource that could get me up and running as soon as possible, I would really appreciate it.
I don't mind spending money on it.
Thanks in advance.
Fabian

A great resource for Android development is the official Android training documentation from Google, as well as these tutorials. Let me know if you still have questions I'll be happy to help.
thanks little question regrading databases

Hi,
Thanks for your help I learned a lot and I'm already planning my app
I just have one question that could really help.
I want to make an app where people on different devices can interact and send each other tasks. I guess I need a kind of SQL server that supports Android, right? Is there a better or at least more economic way to do it if I will have around 1000 users where each one can add people to send tasks to?
Many thanks,
Fabian
And one more question
Is there any way to do a phone number authentication (like Whatsapp) instead of user name and password which I think is a little to tedious for my planned app ?
Thanks in advance
Hola, for the task sending. Would you like to make all task public? Or should you send it like a message?
But when i need access to a server, i use php scripts. But we can take that later, when you have answered my last question
For the phone number authentication, you have to have a online database, with all phone numbers. User inserts their phone number, the first time they starts the app. Then you can retrieve it from the database. But we can also take that later.
I´m glad if i helped.
(Sorry for my bad english.. )
Hola
Well I want it to be like a manager that gives a task to his employee. I want the task to be between them and only they can close it.
Likewise, it would be a problem if I make a simple phone number insertion if there's no validation. I was thinking about a number verification (like whatsapp) to prevent other people from accessing the tasks.
Do you think it's possible or should I go with username and password?
Thanks

I am using OpenShift - https://www.openshift.com/developers - which is a open source cloud architecture in that they offer packages like NodeJS and DB's. They allow you to have 'gears' which I guess is their name for services running on their cloud. The free account has 3 gears.
I currently only have a NodeJS server running to deliver files however (as far as I understand it) you can have MySQL and others as a backend. I would think that whatever devices you develop on would simply log into the DB and look up messages/tasks etc. I would also think that your app could insert those things. The best part is it is free until you reach Enterprise level or so. I would check it out since free is good. Offhand, I do not know what DB's Android supports via java but MySQL is probably one of them.
Just some info for you to examine.
Good luck
Hola, of course its possible! But maybe Username and Password is easiest.
You can use e-mail validation.
I actually worked on a application, there store products in databases. So i have tried it before. Ask if you are confused
And Sum1nil, sqlite is implemented in android, so for local database, use sqlite.
But for online database access, i use php

Hi all,
I have a concept for a single update application that would be driven from the AndroidSPIN release database so all developers could use it for ROM, Themes, Applications and anything releases to devices.
If you wouldn't mind taking a couple of minutes to read this post, I would greatly appreciate it.
http://www.androidspin.com/forum/viewtopic.php?f=260&t=226
I'd really love to get a group together to collaborate and either help design this and/or write an application and back end to do it.
Let me know what you think.
Thanks
Simon
Sounds like an awesome idea, I'd love to help any way I can, but I dont fit in any of the needed positions for the post. Looking forward to see what develops though
Fantastic idea!
I only ever use XDA so god knows what I'm missing out on elsewhere and to be honest after searching the word android on google and trawling through one crap site after another becomes tiresome so hence the 'XDA only' policy.
Sorry I can't offer any programming skills but you have my support on this project whole heartedly, not that it counts for much I know buh MeH!
Hope you can get this off the ground.
As I mentioned to Simon already, I was thinking about building an update application for my ROM. I love the idea of having an on-phone ROM database, update capability, something that can easily be used by any developer in the community.
Some initial thoughts on functionality:
- Browse ROMs
- Download ROMs to SD Card
- Monitor specific ROMs for updates
- Monitor currently running ROM for updates
I'm willing to lend a hand on the Android side of things, but this will be a large undertaking and we will also need some people to contribute to the UI, server side of things, etc.
I do iPhone UI design for applications now (I don't have an iPhone, but most of my contracts and clients are iPhone based), but let me know and I can whip up anything you guys need UI related.
Send me a PM and I can get the ball rolling on how the functionality can be laid out as well.
Even tho I know I wouldnt be able to help out with this. I know I would love to test this out if you needed it.
Its a great idea!!!
I know a teeny bit of Java, and I'm working on becoming an Android developer, so if anything needs doing on the Android side of things, I'm willing to contribute.
Although I may not know as much as some others, I'm definitely a fast learner. I have a few books on Android development I'm reading through right now.

Could be easily done, would require quite a lot of laborious work ripping out all the stuff you wouldn't need though.
I would take a look at this but unfortunately I have another Android project on at the moment which is taking all my development spare time.
@SimonNWalker What sort of backend having you got going? REST? SOAP?
Ups wrong theread
not that it matters (since i kept the source 100% open)....
you have my blessing to tear the cmupdater to shreds if it will give us a unified solution to all our ROM cravings
firefart has done a good job of keeping the code pretty clean so there shouldnt be too many issues with grabbing it
and the new code for the screenshots for themes could probably be used to the advantage of this project with ease
I'm not really interested in a rom updater, but a market replacement with an "upgrade all" feature (à la apt-get / yum) drawing from multiple repositories would be most exciting.
The Cyanogen updater could be used, it just needs some modifications. Stuff like sub-sections and update all
Would probably need a new method to keep track of the updates aswell, I don't think json would be sufficient for a lot of applications and updates. Unless somebody could make some kind of script to automate the process when it gets uploaded.

The only other method I would consider, besides JSON, is an advanced and well thought out web-based form that the developer is forced to complete upon uploading a ROM. This would place more burden on the server, but should be relatively easy to attach the provided ROM information to the rom database.
Think: Check boxes for firmware compatibilities, check boxes for device compatibilities, version number, change log, etc.
Maybe something a little like this?
Wow this would be/ is gonna be awsome!
I would suggest also that you can backup your sd card settings (and maybe also sms...) to an ftp server (or some other server you can install on your pc) from this app...
like (incremential) backup>partition>wipe>install update>boot>getbackupback
problem is to get the server adress back after wipe. maybe stored in web database and encrypted with phone imei number? or uploaded as google
whatever...
or just not wiping that single adress
just saying ^^

JSON is just a file format. The CM Updater works via a static JSON file that gets updated manually. The way I'd design this (which is what I asked a couple of posts back) is a dynamic web service (probably REST based) which delivered JSON dynamically. Wouldn't be too difficult at all.
As SimonWalker said he's using PHP + MySQL I'm guessing that's already being done.
@garok89: CM Updater is completely open-source therefore blessings are not needed to use the source. Really don't understand all the "credit" crap here on XDA.

I know it is open and I don't need to give my blessing for people to use the source. I did so because a lot of people don't feel comfortable using other peoples code without permission, regardless of whether or not its 100% open source.
And as for the 'credit crap'... I don't see you asking for your name to be removed from the 'about' section of the app
I am not asking for any credit
Anyway, lets not get off topic...
Guys, before this becomes Android Open Alliance, the sequel (you all remember how that went), I think we better set up a way to work together first and then toss in the speculative stuff later.
How about starting simple; set up a wave?
Hi all,
I'm a noob app developer trying to do it for the first time. I'm trying to create an event calendar app for company's internal purposes. So that everyone in the company (which uses a lot of android phones) can be updated on company events that are coming up.
My approach is to create a database with MySQL for events input, and to use PHP to connect the database which is in a server and to push it to the android devices that are used in the office as that's how I found it in a tutorial from HelloAndroid.
My questions are:
1. is this the best approach to create such app?
2. Can I use Android's default calendar to input these events? if not is there some kind of calendar template that I can use to display the information to the users.
Probably will have more questions as I progress, but please help if anyone is more experienced in these matters than I am.
Thank you very much, and really appreciate the inputs that I'm gonna get
A simple solution would be to use Google Calendar.
By using GC you can add/edit events either from a PC (work or home) or your Mobile anywhere in the World.
All that is required is for someone to first set up the calendar on Google and push it out to all those who you want to see it.
This way you are not isolating anyone who does not have an Android Phone.
that's a really good point. Especially in a closed environment like an office. I didn't think of that before. THank you very much.
However, if let's say I want to try to build an app for that for public use, not just confined to limited numbers of people in a company.
Would that be the best approach or if there's any better way to approach it. I may decide to build the app after all just to learn and gain experience in app development.
thanks again for the feedback, really appreciate it.
I can't really give you advice on developing an App sorry.
All I can say is the method I mention is the one which I use to keep all my Operational Team (Surgeons/Doctors/Nurses/Admin/etc) updated and advised.
There's nothing short in you developing your own Calendar App but you would have to ensure it would be available to all and that includes anyone anywhere regardless of the fact they are at work, home, holiday, with Android or not, have a Phone, PC, Mac, etc... etc...
For that there's already a stable tool by the name of Google Calendar.
If you do develop one I'd still be interested in seeing what ideas you could bring into practice that would have a benefit over GC.
I understand your point of view, and actually you got me thinking, maybe if I really want to do the apps, I can create an app that calls the Gcalendar events, and display it from the app. I can find out the API to do that, and that would be much simpler.
Thank you again for your input, really appreciate i

No problem.... I wish you well on your venture.
Do please let us all know how you get on.. You never know, if it becomes that good I may even use it myself over the stock calendar App or any of the other's that already link to GC.
Hello to all on this forum.
I have a Flash application that I want to develop into an Android app. I would not require some of the bells and whistles that are currently on the application, but a simple sub-set of how it works now. The flash application can be found here:
FastFood.com/nutrition/
(Hope this URL is allowed here as it will help people understand what I want to do.)
I have all the source files and programming for this and hoped they would be of some help in developing the Android app. But of course, I have no idea if this is any help at all to whoever develops the app for me.
Anyway, before trying to source a developer to do this for me, I thought I should ask a few questions to see if this is even something practical. So I hope some of you can give me some guidance regarding my questions.
1) Are most applications stand alone in the mobile phone, or is it common for some of these apps to access the network to get the necessary data required to operate? My purpose requires a database that is currently 14 megs, and must be accessible to the app, although only small portions of it are needed at any one time.
2) Are there varying systems within the Android family, or versions of the operating system that need to be accounted for?
3) Are there good reasons to develop for both Android and iPhone together? I mean from a cost to develop point of view? Or would it likely be just as effective to develop for Android, then move on to iPhone, or others, as is appropriate?
4) I am guessing that if you have looked at the flash version of our Calorie Counter, you could probably give an educated guess as to what it might cost to replicate a scaled down version for Android. So please, take a stab at it if you can.
Thanks
I'm having trouble finding the right way to locate someone in assisting me with my inquiry... I have an idea for an application, but don't know where to really start. I need to speak to someone who has the brains, patience, and desire to listen. The application would be something that every single employer, company, agency, or individual could benefit from. Anyone willing to contact me via text or email? My name is Jordan.
sorry to break this to you bud, but ideas are like a**holes... everybodys got one.
best way to go about it if you really do believe you have a good idea and are driven to bring it to fruition is to learn to program yourself.
here are some resources:

I may get told off by the hardcore devs who know eclipse and java much better than I but if you want to write apps yourself but are new to it you can use a windows program called basic4android which lets you program in a visual basic type language that is very easy to learn and it then compiles it to proper apk file (no interpreter but a proper standalone market ready app).
I started using it last year and was able to code all sorts of apps from games to anti theft ones quite quickly, and it has a great user support forum.
It might be a good option to try as it is easy to learn but very powerful and means you could put your ideas into action yourself

I still need a developer I can talk to so they can tell me whether this kind of app would be possible to create. Is there anyone on here that would be willing to contact me?
Google programming freelance
Google "programming freelance" and you will find lots of freelancing sites, I personally used odesk in the past, I had mixed success, my biggest problem was the heavy Indian accent, some things are just easier to say verbally then in writing, but if I dont understand his accent, this can be a problem
Hi there guys,
Here's my story, I have this project I want to start working on, and it's suposed to be a running prototype in a month or so.
Anyway the app is going to be pretty simple, it is going to have users, that can be drivers, passengers or both, every user will have to have this info: name, surname, user ID, car which he/she is driving for now pictures are not neccesary(if you could point me in the general direction as to how I can do that, great), and users should be able to send(not instant) messages to each other.
I will also have a webpage in which you will be able to do all the things you can do with the app, so my question is
Where and how should i keep all of this data, all of the info?
I'm a real newbie in this, but I plan on learning a lot, so should I make a database and store all the textual info in there and link it with the app, or is there another way that you are supposed to do that. Where do I keep the pictures?
Any help would be wonderfull :3
Have a nice daaaay!

You need a large server for this, and that has to grow larger by times as new members will start joining and this is going to cost you a tad..... A suggestion from me is that limit the size for each users content, like multimedia, let's say it's 1gb and one exceeded it and the older stuff got deleted
