[Q] Questions on developing android app. - General Questions and Answers

Just got an android project from supervisor and I have only 2 weeks to go to show him all the basic functions of the project, and I'm new to all these thing.
The idea of the project is to get peoples connected to each other without using internet connection, which meaning that we create and connect by our own network like LAN, and maybe others.
We need a database to store data like pictures and chat logs too.
So, my questions will be what kind of database/server we use for android application to store data ? and any ideas on create a own local area network or any kind of other network to get peoples who use the application connected ?

You should look into how companies have created social networking over text messaging infrastructures

Sounds like you are probably going to get fired... How is it you have a job where you would be expected to do this.. but have no clue how to do it. 2 weeks is not long enough for you to "learn" android to do what you need to do. Id tell him now that you are cluless and need help otherwise , in 2 weeks when your project is due, he is going to be pretty dissapointed in your performance.
Better to admit you are a Dillard than try to cover it up.

Ops sorry my bad, I'm actually still a student , just that one of the lecturer assigned to be my supervisor and gave me one project before I graduate. Every students must finish a project before they graduate.
The program might not be perfect but at least it must be functioning.
I did some research and now I have some basic idea on developing android app.
Now I'll need any of you to guide me a little bit, about the database that will be used for android.
Example like creating a Registration interface, allow users to register but without internet connection, meaning that we use LAN or any other kind of connection.
Meaning that we create our own connection and get the users connected together.

[Q] Multi-user login on Android

Have anybody but me thought about having muliple user logons on an Android device?
I'm thinking with the Galaxy Tab and many similar devices to come it would be natural to share the device within the household. Naturally you wouldn't want others to log on to your facebook/msn/email etc.
Are there any projects aiming to do this? Would it be possible?
hey, I'm loosing it trying to find out the same for weeks now. Been trying to start a little project that would involve multiple users on a same device, somethink like the xp's guest user would be awesome...
can sameone at least tell me it's absolutely not possible, couse then I'd finish my search and try for something different, thx!
We just got a transformer tablet at work and we had to tie it to a public gmail account dedicated to this device but multiple users will need to use it and have it tied to their google apps account. This is a problem for us and the apps that 'divide' the tablet just cost too much for what they do. We have at least 4-5 people who would use it. This isn't a situation where we should just have a tablet for each employee. The scientific work we do requires so much equipment that it has to be shared and scheduled. The tablet is just another thing we have to pack up in the morning when we have field work on our project. Multi user android support is needed!

[Q] App Development question

Ok now that i got your attention...
I'm currently developing an android application for 2.1 that uses sockets to connect to a local wifi network and send information to another app which has the role of the server (Client-Server model) My question is this...
What class/methods/tools can i use so i can make a spesific record in the SQLite DB which im using in the apps to create an XML and sent it over from the wifi network? That might require a DTD also i recon but what's the way to do it?
All the examples i found are talking for android apps sending xml's to a web server so that's quite diffrent from what im trying to accompolish!
Why i want to transfer XMLs? In my opinion it uses less CPU than any other java programming technique like arraylist so it will be smoother for the actual apps.
Thanks for your help!!

Just do some googling for Android TCP/IP sockets and you'll find loads of stuff. For development help, there's always Stack Overflow. Same as on here, search before asking, but it's a great site for specific code issues. They do have an Android-specific area. Here's a link to all the Android tagged questions...

[Q] App building software no coding

Hi,
Looking for software to develop an app (preferably offline) which will help someone with no coding experience. I am proficient with photoshop & after effects but I don't know any coding.
I am sure at some point I'll require a pro to write some custom script for me but I want to get as far into the project on my own as possible.
I don't want to be bound by some websites hosting terms, with monthly fees and all this other stuff. Preferably, I'd build my app offline and go from there...I don't honestly trust these websites with little app builders then your app is stuck on their site and you're forced to use their hosting and things like that....if it's my app, it's my app!!! I shouldn't be bound to some website or whatever.
So, preferably offline app builder which someone with no coding experience can use?

Simple search would've showed this. The search button is very powerful and so is google.
What kind of application would you like to create? I could help you build or get you the tools for your app and teach you how to code.

I promise you I've searched extensively and yet to find what I'm looking for. AppsGeyser lifts content from the net and turns it into an app...it remains on the appsgeyser site so doesn't really fit with what I'm looking for...I just want simple app creation software without having to learn code because what I'm looking to do isn't super-unique, it's just for an add-on to my existing business.
Has anyone ever used Wix for website creation for example?? Fantastic user interface, couldn't be simpler yet the possibilities are pretty much endless especially since you can add custom coding if you wish but I've built a few sites with Wix, all function great, all look fantastic...just a shame they don't have the same service for app creation.

It's pretty much just a local directory type app mate....that's why I mentioned above that I am really not trying to do anything unique so I'd imagine there's some nice editing software out there somewhere I could utilise and have my app designed and created pretty quick....like the above example of the Wix website,...you could have a fantastic looking website up and running in a couple of hours.
Anything guys?
Still looking for nice easy app production software.
Buy the Java reference book. Helped me a lot when k was starting out. Its some 1400 pages.
Books helped me the most especially with SQL. Consult me any time if you can't find your answer on Google cause frequently ur gonna be typing code bit have no idea what it does and how it works.
Also use Eclipse. Its like ms word for programmers with auto correct and hints and things that are very useful

Just sounds like thats way more advanced than I'm looking for dude.
I want build an app to ad onto my local directory business and it really isn't doing anything advanced or unique...it's the content that separates it's from other apps, not it's functionality....an app containing a load of menus with click through links (are these called hyperlinks?) to that section of the directory then linked again to open specific entries within that section of the directory....
Surely, there's a nice easy, almost drag and drop, design software out there I can use?
I'm really put off by these app builders I see that are $50 per month or whatever but if I have to go that way, ok. Thoughts? (Appreciate everyone's input and I know it can be frustrating talking to newbies that really don't have a clue so appreciate the input and patience folks!)

I know enough to know that's simply not true...the reason for the post is that there's loads of drag and drop simple app builders out there that require no coding whatsoever....the point in the question is what is the best one and also the embedded question of why are there monthly charges that have such a huge range?
So, no...no code does not = no app.

Eclipse allows drag and drop bit you're dreaming man. There is no way you can make anything work on android when making an app without knowing some basics of code.
So get that book I told you about, get eclipse, and get the book "hello android" which helped me start out.
Android apps are way more complicated than they seem bro
Monthly charges is because to make app building software is so damn hard. Trust me. Try your hand at old school app development. You will learn to appreciate app makers cause no joke its hard as hell

But question is that why any company offer you free tool that helps you to create app without coding knowledge. So only two option is here May be company offer paid tool for that and i think so no as such paid tool available in the market.
2nd option is company offer you online tool where you can create app without the knowledge of tool, in return companies want you to buy their subscription etc... to use that code.
I used some tools for testing person and some of them give you .apk and .ipa file to test your app on device but do not give you source code of app. You can read more about 4 best app building softwares, but as i mentioned that they do not give you source code.
I hope so above mentioned information helps you.
Please don't forget to thumb up button if it is helpful. Thanks
Not long ago, people / businesses in the UK would have to pay at least £12,000 for the development of a simple website, without administration / hosting / commerce functions, etc.
Now, you can produce professional websites yourself with a little cost and effort. Downloading free templates, Adobe Muse, WebPlus X8, etc.
Adobe have now launched DPS (Digital Publishing Solutions) which will eventually become a standalone, offline solution for people that want the ability to create apps on an offline basis, with a one-off cost (no monthly subscriptions).
Without a doubt, such offline app dev software is in development now, and I cannot wait until it arrives.
For now, I use HTML5 based WYSIWYG solutions which work well in good wifi / 4g connection, but with no App Store listing and no ability to push notify, but I can create these without subscription / cloud based resources.
It suits clients that have a user base that would generally be within good connection areas and require their services in such a place.

[Q] Total NOOB needs some help :)

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

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

Where to keep my data

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
