Hello devs
I have been learning android app developing through google and have learned little and from that little knowledge I have successfully developed a syllabus app for my college.
Now I am onto next app development which include Database for storing, retrieving & checking the inputed text.
Suppose for example I had made a UI in which there are 2 textbox each for username and password respectively and a button.
So when I click on that button, it should check that the username and password which is entered are same as in the database.
If yes then I will redirect to another activity and if not it should display error message.
So I am lil bit confuse on how to do that because graphically all is ready but coding is missing on that button.
I have just started learning android programming so if you all can explain me in step by step manner that would be easy for me to understand.
Thanks.

Hi everyone,
This is my first post in this forum.
I am an ASP.NET developer, normally using Visual Studio and C# for development.
I am trying to develop an Android program, for the first time and spending time for researching from scratch.
I know that the developing language is JAVA, and Eclipse is the tool to develop.
What I am trying to develop is an Android program, used in Galaxy Tab.
The program should open a camera, and the user could take a picture and store it on the harddrive. Also this program should have some buttons, and when clicked the user could see different videos stored in the disk. Opening the camera, clicking the buttons should be touch screen.
Does this program seems to be hard to develop? Any advice is welcome
Thanks in advance!
I suggest starting here http://hackaday.com/2010/07/12/android-development-101-–-a-tutorial-series/ They cover basic concepts as well as some more advanced ones. It'll give you a good way to ease into JAVA and since you already do programming you'll probably be able to skip some of the more obvious steps. As for your specific app it shouldn't be that difficult to develop, I personally only did very little JAVA programming but there are code sources all over and if you need something specific to a device just ask in the appropriate forum.
I hope I am posting this in the right place.
I am looking for an Android developer to develop a database application to run on a tablet PC.
If you are interested please contact me
Thanking you

What is that app about..
I am interested..
Thanks for the interest.
The app would be database driven where a user would login and select a certain publications to quote on. He would input the size, discount and about 5 other fields, including calendar dates. The app must then calculate what it would cost the client. The user must b able to save this quote so that they can later enter additional fields or info before mailing it to the client.
The app also has additional information that the user can access, such as readership demographics about the publication.
That's pretty much it. I have a web based app, but not all users would hav internet access when they are in front of the client, hence a stand alone app on the unit. The database on the unit would also need to b updated twice a year.
Let me know if this is possible and how long development would take. I know this is a very brief detail of the app, but if u could indicate some costs i would appreciate it.
Thanking u
JP

hi,
you can email me your contact info and project requirement on [email protected]
Hi samarpatel
I have sent you a mail with a brief outline of the project. Please get back to me at your earliest convenience.
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
So, I need some help.
I want to develop a simple app for my Android phone that lets you input a text when accessing the phone's lockscreen, this text should then be saved in a log file containing not only the input text but also date and time of input registration. There should not be any way of avoiding the input either, entering no text and continueing should result in a log that only contains the date and time.
This should result in being able to check who accessed your device and when. For me this would be helpful. I'd then input a nickname for myself that nobody knows of and if someone tries entering the device using my real name, I'd know it wasn't me.
Now here is the problem, I haven't ever developed an application or anything of the sorts. My only experience in coding would be HTML. Does anybody feel like helping me out?
It's a complicated situation, so I'm not responding to the usual "Why don't you just do this or that". I want this specific method that works for me if at all possible.
Thank you for your consideration.

Hello,
I am looking for a Developer who can create an Android App/Service/Whatever for me to do the following task.
Since I have no expertise in Android Development I am very thankful for any help an will surely send some $ as compensation for the result.
TASK:
The App/Service/Whatever should be able to open up a webpage, perform a click on that page on a button (follow all redirections, parse and use javascript, use cookies) just act like a normal Browser, but completely invisible.
I dont want to see any Icon or UI Interaction. Maybe its possible to realize that only on Shell (Terminal) Level.
The Final Webpage's HTML-Code should be saved in a file on the FileSystem (/data/Whatever/page.html).
The App is only for me, my device is rooted and Running Android 4.4.1 .
I hope that someone can help me.

They are really the best company I used to work with!
Check out this app,
https://play.google.com/store/apps/details?id=com.itsjust140.news
It loads webpages. It caches those webpages so we can use the app offline. It's made by me. If you want something like this, I can do it.
