Skills required to develop very basic accouting app. - Android Apps and Games

I have this query regarding android app development.
I'm planning an app, which is going to be very basic accounting app with just plus minus calculations.
I've already developed it in excel & its working well.
Don't want to convert it with 'excel to app' applications which are available online..
May i know what all kind of language skills do i need to execute my first android app from scratch.
And where should i begin.
Thanks & Regards

I would suggest that you learn Kotlin. Its not that difficult. You will get a hang of it quickly.
Here are a couple of links to help you get started. (oops. I am not allowed to post links) But you can search in the site try(dot)kotlinlang(dot)org
Also look out for the "Kotlin for Android Google I/O Intro" it is there on youtube.
Good Luck! :good::good::good:

Thanks for educating me bro. Seems to be very positive & helpful start.
Other than writing some basic excel formulas I don't have any language skills.
Is it advisable to learn 'Kotlin' straightaway without learning JAVA.
Will i be able to create commercial app with this.

Sorry for delayed response.
yes. it is better to jump into kotlin. dont go through java.

I have only one point in addition to what has been already mentioned.
Write the spec well.
1. What screens/inputs will be there
2. What are the functions support
Also write the test cases before you write a single line of code.
How will you test whether your app works? What inputs will you give?
What if you wanted break your app by testing? HOw will you try to break it?
Write everything down. This will help you a lot.

Hi,
To develop android calculator you need to follow the flow chart. First you have to design layouts for application and after that you need to ready the back end. Once the backend is ready, move on android side (front end).
Just simple technologies are required with plus, minus, multiple and divide functions to develop such app. Regarding technical language there are many options, but i would suggest to go for the Java.
Thanks

How to make an app?

I'm putting my theming project aside for now and get onto creating an app that I've always wanted to create that I do not see ANYWHERE in the market, forums, android websites, etc.
I've been reading and reading and reading different threads, instructions, etc. But no clue where to start. I've been reading on App Inventor but realized that it is very limited and I have my high doubts that App Inventor will not be able to achieve what I have in mind to make.
I've got the latest SDK and AVD Manager, JDK, Java, and have been using my emulator to test edited APKs. I'm pretty sure I'll be using my emulator to see how my app progress is coming along and see possible FCs and other issues and correct them as well as adding more to the app to make it even better.
But right now I'm stuck at where to begin here. Right when I was about to create this thread, I was making the name of the Title of this thread and was given threads relating to my title name and saw one thread that was sort of mentioning what I'm asking here.
I read the link provided in that thread ( http://developer.android.com/guide/topics/fundamentals.html ) and got some clues but just not enough to get me started here. I just need that push to get me going and eventually push it out to the market and make some money as a side project and learn from that and possibly make more useful apps. I cannot disclose my ideas here because then someone else (who has experience making apps) could take those ideas from me and go make it.
Is anyone willing to work with me here to get me started? I've helped countless people so it would be nice for a change for someone to help me out here.
There are so much Android development books on the market that I suggest to start with one of them. It's the best way to get some knowledge of the design principles used by the Android development framework.
Another method is to start with some examples found on the web. Just search for Android examples or something like that and you get tons of links
Another method is just to create something, get stuck and try to search for a solution (the most pragmatic method )
Yeah I know. That's why I'm constantly researching. I'm seeing some similarities between Java coding and building scripts in IRC (which I used to do, nothing big, just really small stuff). But my main problem is knowing what exactly are the main tools I need. I've had Eclipse for awhile but never used it. It has a lot of stuff in it and I get lost after a couple executions.
I'm just anxious to get started somewhere and get the momentum rolling for starters.
Could someone point me to a good book/ebook ? There are many out there but I'm sure that are some better than others...
If any french-speaker knows one in Voltaire's language, I'm in too. But English is fine...

Yeah, a good book (english) would be great. Can anyone recommend one?
You don't have to buy books but they do contain a lot more info in one book and would be better to have than trying to scour the internet and pull a bunch of infos together and try to put it together to understand step by step on how to get started and everything else.
Here's a link to a lot of android development books:
http://www.amazon.com/s/ref=nb_sb_s...pment&sprefix=android+application+development
Here's a link to some more info to getting started that is also useful:
http://developer.android.com/guide/basics/what-is-android.html
You may also need to get a Java coding book to help you put codes together properly and understand what each coding does, and tweaking them to work better.
Here's the link to Java coding for Android stuff for beginners:
http://www.amazon.com/s/ref=nb_sb_s...x=java+for+dummies&rh=n:283155,k:android+java
I just bought 2 books for Android application development and looking around for a good Java coding for beginners.

I think any java book will do, as long as it covers the principles of object oriented design and the data structures used by Java. You don't need any info about GUI programming in Java because that's all covered by the Android application framework.
The best Java books are the ones written by James Gosling et al, the designers of Java. But that may also be over the top for Android application development. Just some basic Java will do to get you started. The algorithms needed for basic apps aren't that complex.
App Inventor is a great tool to develop your android app. It simplifies the development and the editor is very intuitive.

[Q] How to make an Android app?

Hello people
I've wanted to make a Android app for a while now but I don't know where to start.
Can someone give me some pointers on where to start.
If it involves coding then be warmed I'm a complete novice at that.
No coding method: search Google for Android app inventor.
Coding and better method: Android apps use JAVA. Take some basic online courses, then learn the Android sdk. (functions that are specific to android)
Option b is better, and if you have a little patience it won't be too hard.

If you want to get somewhere forget the app inventor and invest some time.
Start by using google on terms like "android tutorial" "android hello world".
Download eclipse and the android sdk (google has all the info and tutorial on how to do that).
The sdk has ALOT of very good example apps. From 3D drawing to system infos and interface layouts.
AAAAAAAAAAAAAAAHHHHHHHHHHHHHHHH Google app inventor is doing my head in.
if anyone is reading this on a scale from 1 to 10 how hard/complicated is making a app using coding?
Depends entirely on what you want the app to do unfortunately. If you can give some basic ideas of what you want it to do it will be easier to say how hard it will be.
well all id like my first app to do is when it starts up to show a picture with text then link you to a web page.
Nothing hard
Thats not too difficult, you could patch work something out of existing tutorials/example.
But its always relative saying how difficult something is.
It depends on the person...
Well sorry that's not helping much. I'm still at a loss on what to do.
Basically all you need to do is copy and paste the code from some tutorial examples, or you could even use the app inventor as you need barely any code to do this, for example:
http://developer.android.com/guide/topics/graphics/index.html
http://developer.android.com/guide/webapps/webview.html
Putting it all together and making it into an application shouldn't take you more than half an hour once you have gone through the starter tutorials to understand how and what it is you are using.
Ok I'll try that.

omg
i really wanna learn, so i went to purchase course and
DescriptionsAmount
Diploma in Java Programming.Diploma in Java Programming.
$1,695.00Item price: $1,695.00
$1,695
are you serious??
Well if you are really determined to learn it, you can manage doing it on your own too, with the help of free online resources. Search for a tutorial series on youtube. Here's one I had found useful when I was learning:
http://www.youtube.com/watch?v=Hl-zzrqQoSE
You should also buy a good book on Java programming and read it. That would help a lot too.
read android developers guide
You can check android developers official site it has lot of tutorials and resources.
You can go to next university library and borrow any Android book. It will not include the latest version of OS, but it will have lot of fundamental information in one place, written by one person. Tutorails often show you how to solve single problem only.
Thank you
Also great video
You're Welcome! Yes it is a great video. That guy really does explain it nicely.
Is App Inventor still working?
Look also at cornboyz tutorial on youtube. Same guy, slightly different tuts

basic4android development tool

Hi all,
I searched here on Android forum but I did'nt find any reference to this very nice development tool:
http://www.basic4ppc.com/
does someone of you know it? what do you think about it?
I find it very interesting, special for people (like me) that has some programming skill but not a specific java knowledge... it costs a reasonable price (starting from 39$) and it seems really powerfull, with a very original integrated designer tool... I'm thinking to buy it... I would like to have your dev's impressions and evaluations...
[mod edit]
I am using it and I think it is an excellent development tool.
Takes a lot lesser time than Java and if you are familiar with VB or any other Basic, then you will be up to speed in no time.
Besides they have very good support.
Any more reviews? I'm very interested in this application.
love it
personally i love it. the fact that its fast (and uses basic ) . its just a great program. they also added error support for your internal coding mistakes....so they are really moving forward...if your a student you can get a %50 discount on the enterprise edition . ( i did )
i had the same issue
thank you guys for sharing
I am also interested
I am just learning to make apps, I literally have no experience yet. Would Basic4android be good for the type of app I'm trying to make?
I am needing to make a fairly simple, mostly text-based app, kind of like a user manual/instruction guide. Key features I am needing for this app would be:
*a "find" like CTRL+F to find words or phrases
*an index to jump to specific sections
*rip/copy protection so people can't steal the text and put it on a different device or computer
*smooth scrolling and fit-to-screen text
I know nothing about coding but I am very willing to learn! if this program makes it more simple, please let me know!

Basic for android could and would work. It is based off of visual basic. Which is a windows based code format...
I would recommend learning JAVA. Basic for Android is mostly for people who already Know visual basic....such as myself...
Learn Java. There are MANY xda tutorials on it.

Yes, B4A and B4i are both awesome, easy to learn and very powerful, best on the market, no exceptions.

[Q] Good C/C++ learning resource?

Anyone know of a good resource to learn C/C++? Or if you know C/C++, where did you learn it from? I'm inevitably going to be taking a course on it this comming year, but I'd like to get my feet wet beforehand.

from...everywhere.. even from Youtube's courses !
you need an IDE and start your first "hello world" application
the question is not "where" but "when "
search in google you have lot's of stuff
search in google you have lot's of stuff
Programmatic logic with this languages is a good start then... searching for the basic I found this http://en.wikiversity.org/wiki/Introduction_to_Programming_Logic#Introduction, just take a look and see if help, is the basics with some samples. The logic is the same in all languages, the only thing different is the syntax and the meaning of some commands.
And you can search for what is need to create programs with C/C++ (TIP: http://www.bloodshed.net/devcpp.html)
Not only for C and C++, after you learn programmatic logic, you can search for the documentation of both languages to apply this knowledge, and with the documentation you can search for the basics and a lot of exercices, where you can find easily at Internet. The best source in my opinion is a good book and the documentation, foruns and communities after... then challenge yourself with your criativity. The best place to find exercises of any kind is at Internet, but always try to find, when possible, at least a piece of some book pages about.
And ruscan.calin sayed something important: "the question is not 'where' but 'when'"
I like this thread very much !

Hey !
I do not want to discourage you from the beginning
also you asked a very good question and good decision to learn C language
the most powerful in my opinion even Android kernel is made by C language !
good decision and good luck to you !
Well thanks. like I said I'm going to be taking several programming courses, so i'm definitely going do be a developer of some sorts in the future.
learn java is better...u can make android app...

My goal is to learn both eventually. C++ has low level applications, and Java has high level applications.
I recommend you to buy the E.Balaguruswamy Book which is best one your learning course.
Maybe Java has high level applications, than C/C++ , I consider that better will be first of all learning C/C++. By English I saw good tutorials on cpp4u[dot]com.
BTW. You can try programming using C4Droid on your phone :laugh:

How to become a developer?

I would like to become a developer. Obviously, that means learning code, but which one? Also, I don't have a PC with Linux OS, so will that be any problem? What tutorials or ebooks or stuff like that do you recommend to start me learning?

Yes, that's right. To become a developer means learning to write code and apply those while creating a software.
Question on which one? is completely upto you because you need to know what are you aiming for. If you're looking for web application development, you may have to study any languages like PHP, DotNet, Java - J2EE/EJB etc.
If you're looking for Android application development, first step is to study Java, because its the main language used for programming apps. Then you can move over to Tutorials on Android development, and it will be easy. If its iOS app/ Mac specific app development, Objective C it is.
Not having PC with Linux OS won't be any problem, because you can do these in Windows platforms or in a Mac.
Tutorials = Google my friend. It has almost everything in the universe. Also in Youtube, you get the video tutorials.
Some which I could recommend is, for Java Oracle docs is good and "Java - The Complete reference" by Herbert Schildt is a good book too. For Android, you can find all resources in the App development forums.
You can try out the freepascal with a good IDE (codetyphoon), simple to make windows or linux graphical apps, or the visual studio express with c#.
