The Communicator app: Where to start with Android app development

Hey guys
Aight so the idea is to create an app that lets the user speak to someone in a different language. You make a recording and using the same function that the voice search feature has that recording gets translated to typed words on the phone. The app then uses some translating service like google translate to convert that writing to a language of your choice. That writing will then get read* by the phone and can be heard through the speakers. So essentially you can talk to someone even if you dont speak the same language.
*I know this is possible because I used to have an app that did just this: it read out loud what you wrote down
I have no experience with android development, and not very much with programming either for that matter (ive done some python stuff). However, I thought of this, which dosen't seem too hard to create, and I thought this would be a great way for me to start off and learn about app development.
Ok so because most of the features already exist it should just be a matter of patching them all together (right?). This is where I need you guys' help. Any suggestions on where I could start?
I appreciate any help, no matter how big or small!
MODERATORS: I wasn't really sure if this was the right place to post this, so feel free to move it to where ever you find suiting if this isn't right.
I would love it if someone wanted to work on this together with me, but
PLEASE DONT BE A D*CK AND JUST STEAL THIS IDEA!

Hi,
I'm relatively new to Android myself. But in my understanding, I would suggest the best method to start coding this app is, to build a Service which is intended to do the network polling, and the translation for the App in Background. So I think you need a server which tracks your Messages, and serves the data for the app. U have to look at IPC (Inter Process Communication) to communicate with you service.
If you finished all these, then you can start to build an Android Activity to communicate with your user.

[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

Where to start in Android application development?

Hello everybody, long time lurker, first time poster. I'm posting to ask about where to get started in developing Android applications? I have half a degree in computer science, am familiar with coding, and work in Android software QA, but I'm trying to get my skillset up to the next level and actually start developing applications on Android. Is there any specific books or literature I should read to get me started on my journey? I'm also a long time IT guy on both Windows and Unix-based systems, so I'm by no means computer illiterate. I'm also a long time phone modder as I've been tweaking Android phones since the original G1 running 1.0. Thanks in advance!

Take a look at the Android Developer guide. It has samples and tutorials. If you google, there are also several free PDFs on the subject.
A good Java book will also help a lot. Just start to write a few trial apps and you will get there quickly!

The best place to learn for me, is android web page:
Here you have everything to start:
http://developer.android.com/guide/index.html
And to set up the environment for developing:
http://developer.android.com/sdk/index.html
If you want to learn from the scratch, the links I posted are your point. You can also take a look to the tutorials:
http://developer.android.com/intl/es...llo-world.html
You can also start with java, if you want.. I reccomend you take a look to this:
http://download.oracle.com/javase/tu...ava/index.html
http://download.oracle.com/javase/tutorial/
and start from Java SE 6 (http://download.oracle.com/javase/6/docs/)

I don't know what your college classes are like for CS, but you should have the basics of programming, why not start writing some Android apps?
Start with the basic "Hello World". Get used to working with main.xml and TextViews, EditViews, ListViews, Buttons and Listeners. Android is mostly JAVA, some Android-specific operations and your xml files.
Take some of your CS 101 type programs and try to write them on Android. The more programs you write, the more you learn.
Try to learn something new everyday and in no time at all you'll be impressed with how far you have come.

Yes this is really a good advice
Just start writting little programs and you will go up soon
You could use the sample code that comes with the sdk, and start with different things: First, layout, xml and the like. You could then start with some othe things, like services, broadcast receivers, content providers, to get the feel of them. And finally, work with the hardware: Internet (wifi or 3g), bluetooth..

At Barnes and Noble there is a book called Android App Development in 24 Hours. It is a freaking great book. Helped me a lot when I started. It breaks down the chapters in to hours with exercises and explanations. Being familiar with Java fundamentals would be good, but not necessary. The first couple hours(chapters) explains the a general overview of the history of the OS and helps you build your first app. My favorite part of the book is how it teaches you to build and app piece by piece over the rest of the chapters adding new features each hour. So, by the end you have and app with quite a bit of features that work and you actually understand how and why. At the end, you have an app that has a lot of Android features as well as knowledge of how they work and can be used. It doesn't go into the more advanced features, but it is well worth the money for beginners. I still use it as a reference because of the easy to understand instructions. Sometimes, the Internet guides assume you have been using Java for 10 years and skip how and why they are doing something. And even then I doubt every veteran Java programmer remembers everything. I am half asleep so forgive any grammar errors.

Really good tutorial for the first basic steps. In terms of installing eclipse/java and hello world. He continues with his tutorial in part 2, part 3 and so on.

Android/fruItphone app. idea needs help...
If there is anyone who has knowledge on building apps for Android, I would be extremely interested to share with them an idea for an app. I'd hope this app would be able to work on that other fruIt based dumbphone, too.

Well, there is planty of developers out here I'm one of them (thought not the smartest ) so, if you want to share the knowledge, feel free to PM me

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.

[Q] a few questions about webRTC on android

hi all,
I have a few questions about webRTC on android. I can say I'm new about android and webRTC but I can also say I made tooo much research about webRTC on android. But still have a few questions. (some of them because of I'm new, and some of them because of I'm okey but not fully)
I'm trying to make an android app which is going to communicate between web browser (first choice is chrome) and android device directly (p2p we can say). So I made too much research and I found webRTC is good for me. Do you advise me something other or is it okey you think? (also I am going to code a plugin for chrome).
Nearly every document says 'android is not directly support webRTC'. So I need something to provide me webRTC on android. What it is? Is it native android that I have to code? Is it native (NDK) library that I have to include my project? Or is it a java lib? Or should I go for cordova/crosswalk or sth like that? I researched all but didn't find something can help me. Yeah there are documents about it but not enough..
Some of documents says, I need chromium. But why and how? They show me lots of linux terminal commands and even there is no a line java or C or C++ code. Even some terminal commands and links that they give is not working.
I read/found/tried these things as a result of my research:
Apache cordova
Crosswalk

https://github.com/webrtc
http://webrtc.github.io/samples/
http://simonguest.com/2013/08/06/building-a-webrtc-client-for-android/
http://orcaman.blogspot.com.tr/2014/07/building-native-android-webrtc-source.html
https://github.com/pchab/ProjectRTC
https://github.com/pchab/AndroidRTC
in a nutshell I need help. Please give me your hand. Thank you. (because I'm really very helpless and tried to do my best)
Thank you.

Any idea? Any help?
