[Q] Getting Started - Android Software Development

I want to make an application for my phone, I have all the necessary programs to create an app. But I do not know the "language" used in the programs like eclipse. I'm assuming I have to learn the code but don't know where to start. Anybody have good sources for learning it?

There are a number of free lessons and tutorials on Java floating around out there. You may also want to check out http://forum.xda-developers.com/showthread.php?t=667298. It has a lot of information that may be helpful in it.

Same here. Thx for the info!

Please help, info about using java on wm with c# & googlemaps api

Hi first I must apologize for posting here I know I should post in the questions and answers section, I have already done this twice with two similar posts but I have not received a reply I beleive because the expert programmers are less likely to look there to help people as most questions are about useing software not developing it. anyway here is what i posting before I really hope someone can help me...
Hello everyone I was wondering if anyone could answer this question for me.
I am creating a wm app and for part of it i want some information from googlemaps, the maps api is in java and i was thinking of ways to incorperate this into my app. Can i create a java program to get data from google and have my c# program run the java program and get info from it? I could write my program totally in java but i don't like the way i have to first start the vm and launch my program from that is there a way to automate this? also I need quite a lot of information from the phone so using c# will make getting this info easier.
or are there any other ways i might be able to get the info I want, I don't really know anything about applets but could they somehow be used?
oh btw the specific data i want is distance between to map locations (via googles route not direct)
many thanks i hope someone can help
I apologize again for posting in here but this app is for a final year project and I need to know if im barking up the wrong tree as soon as possible.
I might be wrong here, but to the best of my knowledge, Google Maps API is actually JavaScript API, not Java. If you found Java API, it's most likely a wrapper. And if it exists, I'm sure C# wrapper should exist as well. You might want to take a look at this. I know it's not exactly what you are looking for, but it might be helpful to some degree. Also, one other thing I can suggest, is to look at Virtual Earth API. I'm almost 100% positive, that they do have a C# implementation of the API.
Hi hobbbbit thanks so much for your reply, so googlemaps api is javascript , I have never used javascript before and saw that the api used objects methods and looked like java so i just assumed thats what it was. If there isn't a wrapper for c# do you (or anyone) know of a way of using the api to obtain one of the objects and use it in c#?
I would use virtual earth but unless I am totally wrong here I thought to use it you needed a licence which costs around $8000 which I don't want to pay for. Even with google if I wanted to release the app i think I would have to pay although I have contacted them and they say I can develop my app using the free api.
**EDIT**
Ok well I took another look at virtual earth, I really am a complete idiot. I signed up for a FREE developers account so hopefully everything I need I can get from there.
again thanks for your advice if you hadent posted I would probably still be trying different ways to hack google earth to work in my wm app.
On codeplex is a windows forms project that uses googlemaps api as wel as a few others. Im pretty sure you can get an idea of how to go about this from there

Superb this was just the thing I was looking for I will be sure to study this code closely. Thanks so much for the information.

[Q] First Android Project

I'm looking to start my first Android but I'm not sure where to start. I want to make a launcher app. Is that a little over the top for someone who has never written in this language before?
Have you done any programming before?
A little bit of Java not much though and some Python but that doesn't seem to matter much.
Check out this thread I just made:
http://forum.xda-developers.com/showthread.php?t=814908
It could be a valuable experience for you. If we find the right people, you could learn a lot AND still work on a Homescreen-app. I don't now about your current ideas, but I'd be excited to hear them.
Check out Resources in Android Developer website.
You can start with a simple Hello World app, and move on from there.
Hello Android!
There are more examples in the left navigation.
Have fun
Actually Python helps a lot. Try to learn C#, it's structure is very similar to Java but easier to learn.

[Q] First app; Advice? Examples? Warnings?

Hey everyone; it wouldn't let me post in the development subforum due to the fact that I just joined, but I figured my topic would be just as relevant here.
I'm a sophomore CompSci major. Java is my strong point, but I'm far from a master. I know syntax, I know how to follow what's going on in more advanced programs, but writing them is the tough part. Anyway, I would like to create my first app; something simple. I was thinking a calculator with a small clipboard on the side (hold the button to store the number displayed in the window, hit it to place that value). It would be insanely helpful for my physics class.
So a few questions for you guys:
-Is there anything I should know beforehand? Anything to be careful of?
-Can I use Eclipse? I tried with App Inventor, and it's too limited.
-How do I obtain examples of more complex apps? Can I unpackage the apk files into java classes?
-Is there a site similar to the sun library, where it lists the available classes/objects/imports?
I'm sorry if I don't know the lingo just yet (of Droid or Java). Picking this all up is a little difficult for me, but I'm trying
Thank you in advance for even taking the time to read this. I understand rookies must aggravate you guys, but from what I've seen, the community has been nothing but welcoming!
You can definitely use Android SDK with Eclipse.
This guide will help you with install and set up process
http://developer.android.com/sdk/installing.html
SDK also contains sample projects that you can use for learning.
I don't remember about unpackaging apk files, but I'm pretty sure they contain already compiled .class files, which will be of no use to you.
And here's Android's reference page:
http://developer.android.com/reference/packages.html
Also the dev guide is very useful for learning the basics:
http://developer.android.com/guide/index.html
Resources section has useful tutorials as well!
Hope that helps. Good luck with your app!
Thank you, meshdub! And all branching from the same site; sure made me look bad...but on the upside, you've introduced me to a source I will be able to use throughout my software development lifetime.
If there's any more you or anyone else could give me as far as what to expect or look out for, please let me know! I'm honestly a little intimidated by this; I'm not too familiar with forums, and I've heard how difficult app developing can be.
But this should keep me occupied for a while, and again, thank you very much

skill set required for android development!!

Hi all,
I want to start application development for android. Can anyone please let me know the requirements for this?
I know that I am asking very general question and please let me know if this is not the correct place to ask this query.
I know C/C++...what things I need to learn before starting application development for android?
Waiting for reply!!
From what I can tell:
Java.
Then hit the android developer's website and they'll teach you how to write for android platform.

Thanks skulk, but do I need to start learning Java from scratch for that?
Can anyone please guide me in this?

Well, it's pretty hard to learn a new programming language from the middle!
Go to the Android devs site... There are plenty of tutorials there, as well as links to Eclipse (favoured Android development platform).
sorry to be so naive...but what is the link of android dev website?
Clicky the linky.
many thanks floating man. I didn't knew that this is different forum from any android developer forum...btw can you please let me know the difference between this forum and any android dev forum?
This is a general smartphone forum, mainly catering for HTC made devices, but covering "some" others as well.
Thanks floating man. I will subscribe to any of the android dev forum and ask the same query there. But there is one doubt: whether such a basic (and naive) query be resolved there?
Do you recommend any particular android dev forum?
since you already know c/c++ you already know the basics of programming which are the same for each language i guess.
in my opinion writing basic/simple apps for android is more easy than writing the same app in c/c++.
so for basic/simple apps you could start with some general java tutorials especially about OOP and then go on to Android ...
just simply Google search terms like "android development for beginners" or "android app development tutorial" and plenty of websites come up offering handy dandy hints =]
Thanks elgubbo,
I will try that and let u know if thwre is any issue...let me kbow if anyone else has any suggestions....
For me it always helps to try to understand other code samples. Thats why I am looking for a book wich explains a few basic (and some advanced) code samples.
Sent from my fishbowl...
Java was originally created as a successor to C++ and if you know C++ the syntax of Java should look very familiar. It was designed to make OOP concepts more accessible to C++. It was also set up to make pointers and memory management a thing of the past.
Actually in a lot of ways, knowing C++ will give you an advantage over devs who only know Java. Eventually you'll be able to use Android's NDK (Native Development Kit). Although you will have to use some Java as all apps require the use of some java and the SDK on Android. But even then, you'll have a better idea of what is happening "under the hood" due to your C++ knowledge.
As for where to get started I would suggesst learning applications fundamentals:
http://developer.android.com/guide/topics/fundamentals.html
Especially the Activity lifecycle and Component lifecycles.
Do all the "Hello World!" tutorials and then you should be well on your way to becoming the next Angry Brid..... err Angry Bird dev.
Thanks alostpacket. That is a very useful link. I will read it and let u know if i have any queries. I just have a doubt, moreover, i am fearing because i have only written simple c++ programs till now. Will i be able to do it?

Instead of being scared by it, TRY it! Install Eclipse. Install the Android SDK. Try the tutorials. Only you can know if you can do it or not.
Thanks floating man for supporting me, however, can you please let me know the place to help me out regarding very basic queries regarding starting programming...like I want to know what eclipse is, what is SDK (I know the full form though: Software Development Kit)
Is the place...http://developer.android.com?
Actually, I have worked on C/C++ at very basic level where we write programs in IDE and save the file as either .c or .cpp
These seems to be very basic things.. that i should know..i can read if you have any link or doc..

Yup, That's the correct site. They have a whole section to get you started using eclipse there too.

Android app development help?

Hello, I am a computer science student and i need some help getting into android programming, i know a bit, but frankly it aint much.
I know C++, C#,Visual Basic,(I know C++ the most) and i am currently taking a class on Java, but I want to get into android programming too!(I made a game for android a while back using unity.)
I don't need a tutorial from the ground up.
I know how setup the environment, sdk, run, etc.
I want to learn how to work with layouts and make them look cool,
basic app functionality, work my way to internet connected apps, databases, apps with root, gestures, all that fun stuff.
I am just wondering if anyone would share any info or site that helped them.
I am not that much of a noob to programming but i am to the android sdk and a rookie with java.
if any mentor would step up or something i would really appreciate it.
Thank you.
btw if you're feeling bored check out my game!

Yes, i know its hard, i have a better version, i just haven't compiled and uploaded, i will soon.
I think best Website is always developer.android.com.
It hasn't only the API reference, but also Training section and much more.
Whenever I don't know sth I first visit this.
Regards
According to me you should go step wise step...Watch video tutorials on YT.
You can ping me for help.
Thanks
then go to java website and start learning java. Loads of tutorial stuff is on their website
java.com
then go and download the Android SDK in about 2-3 months when you've completed the above.
