Simple Calculator App Development Help - Android

Greetings, here is a simple calculator app that I am developing in Flash Builder with Flex, which basically uses java and xml's to develop. Although I have the basic logic down as for how I would like to approach this type of APP, I would like for some one to help me structure the coding. I will upload the source directly along with screen shots to help. XDA Developers won't let me upload the coding within the actual post so I have provided them as attachments.

If you're building a tip calculator, you might want to take a look at the source code of this example app. (It's from a book I'm reading "Android How to Program")
Edit: I just realized you're developing an app using Flash.. This post may not be of use to you. If so, just ignore this and move on.

Either way thanks. For the reply. I appreciate it

who knows im sure it can be useful, im not a ROM dev or anything but access to the API's im sure will be nice for them.
Common Controls API
Common controls are UI widgets and components that will provide developers with the ability to provide the Sense UI look and feel to their applications. API documentation and sample code are provided as part of both the phone and the tablet add-on extensions to the Android SDK.
Stereoscopic 3D (S3D) API
API documentation and sample code that illustrates how to programmatically enable the 3D display mode of the parallel barrier based screen for various types of applications. This API is provided as part of the phone add-on extension to the Android SDK.
Tablet Pen API
API documentation and sample code for providing a framework for fully fledged drawing and painting applications as well as full access to the pen events at a low level. This API is provided as part of the tablet add-on extension to the Android SDK.

[Q] Am I on the right track?

I want to develop android apps.. lol I downloaded JDK and eclipse.. I am familiar with the concepts of coding html, php, exceptions.. Do I need a TON of knowledge to get started? Can someone link me to some basic walkthroughs?
If you don't have Java knowledge, then your options are Phonegap or Titanium Appcelerator!
Using phonegap, you will be able to write apps using HTML+CSS+JS. Read about it.
See if these http://developer.android.com/resources/browser.html?tag=tutorial are enough to get you going. Maybe after that look for a book. I've been using a more recent version of http://www.amazon.com/gp/product/1934356492. Then again, maybe it isn't the best book to use, because I haven't actually created any apps of my own yet.
Cool thanks for the help. I am gonne get the lynda.com tutorial and a java book. Im sure all coding has the same basic concepts. Maybe I can make a useful app one day lol

[Q] Can I create an android app without knowing java?

i want to whether i can create an app without knowing anything about java..i have installed the sdk but can't go any futher..do i need to know about java??
If you want to actually program yes... I believe there is an easy app creator out there, but you won't get too far with it.
I just started learning Java, picked up a book and im getting into it. Oracle has online tutorials as well as Android Developers, you can follow those to get a gasp of it. The real issue is learning the in's and out's of java to bee more creative.

Take a look at illumination software creator at radicalbreeze.com . No programming experience necessary. There are other apps like this.
Sent from my Galaxy Nexus using xda premium
Simply put yes you can. There are other language alternatives. C# (mono project) and there are a few different implementations to allow you to write javascript for apps as well. Also check out app inventor, it lets you drag and drop program. No typing involved.

Android programming Java help

Hey everyone I've gotten into the app making and stuff and for anyone who knows about Java I may need some assistance, I've been building a game kinda basic but its my first app and its still got bugs, I'll post my source code later but its in the multi player score keeping that does not work. But single player does. Here I intend to make all my source and apps for the most part free especially this one once I get a Google dev account here is the link

Give it a try tell me what you think it may need added to it so I can see what I can do thx

If you put the download on a server that doesn't require one to sign up you will get more feedback regarding your app just a hassle to sign up to download something kind of trivial and unknown (I was downloading so I could give you some positive feedback but having to sign up and make an account deterred me) I think others may feel the same good luck bro

Beginner

I have recently discovered that I would love to start developing Android apps as a hobby and I have completed this set of lessons - http://developer.android.com/training/basics/firstapp/creating-project.html - successfully but now I want to learn more.
If anybody has any "making of" videos/series of people developing apps (in Eclipse) then please can you link it here.
Thank you.
AW: Beginner
Did you already go through all this tutorials http://developer.android.com/training/index.html?
wow cool. Didnt know that they offer such Lessons. Just always get redirected to the API. Did someone really made all the Trainings before creating Apps? I dont think so but its a very good starting point

I just found another interesting source for learning how to build an android app
http://www.vogella.com/articles/Android/article.html#firstandroidapp1
I also found this app from video2brain: http://www.video2brain.com/en/android i didn't try it yet but it looks really interesting

I would recommend taking a look at The New Boston android app development series (http://thenewboston.org/list.php?cat=6) it covers everything from essential basics to more advanced topics like databases and using OpenGL, among other android development topics.
