Hi everybody,
So, I'm volunteering at a non profit and recently I was approached with a proposal about an app for the organization which would consist of a small questionnaire to tell people if we can help them. Something like:
o Are you between the ages of
o Do you live in
o Are you unemployed
o etc. etc.
And the radio buttons would work as check marks that depending whether these are checked or not, an if then would kick in and direct the user to another page, either proceeding instructions or a sorry, you do not meet the criteria.
I'm familiar with some coding, a little fortran, java script and php but I just have no clue how to create an app. I downloaded the developing tools from google but I'm just blank. Can someone point me on the right direction or maybe there are templates of this kind that need just a little tweaking. Any help would be greatly appreciated.
I'd suggest you creating just a web page
I have made a demo trogper.cf/surv_demo
No, that's the easy part, I'm still fresh on client side programming. What I want is an app for android.
Hello
Eclipse or Android Studio are necessary tools to develop native java apps for Android but you should have basic java (and at least OO language) notions to code it.
Get Eclipse or Android Studio.
Then...
There are loads of tutorials on the net for basic android/java programming.
For example...
mkyong.com/android/android-checkbox-example/
tutorialspoint.com/android/android_checkbox_control.htm
would get you started with your app.
you'll need to put www before the links, i'm new so not allowed to post links yet
If you want to simplify your life a little try NativeScript or Corona SDK.

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.
This is a great place to start:

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!
http://forum.xda-developers.com/showthread.php?t=2495430
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.
how to convert Shell script to apk file?????
hello gud evening to all
i am a ECE student...anyone can tell me how can i make a apk file by the use of Shell script...i have a shell script and just want to make a apk of this...
need help please...:crying:
Okay so i have been reading a lot and programming for weeks.
I am getting very comfortable with the android api. i've built a few of my own ****ty apps..
now i'm looking for a project to work on, something simple but not too simple either.
I need a little help with fragments and layouts and such, so if anybody has an idea for a project i could work on
or could teach me about fragments, feel free to post please? xD
Good day everyone,
Please I am very very new to Android App development, I'm a complete nob but I really have a desire to build apps for the android platform. I recently downloaded an android tutorial pdf which I use to practice, I have installed on my PC ADT and Android Studio, but everything seems to complicated to me, the java language and everything looking soo hard. I managed to sail through and mastered the codes for Activities, Services but I got stuck when I got to the Content Providers chapter of the tut. The thing is I dnt knw how to write java.
Please what I need to know now is; what is the most basic of Android app development? Where do I have to start from first? and the steps to follow.
Thanks alot in advance

If you're completely new to Java (and programming in general), you should learn it first. You don't need to know everything, but you should at least learn the basic syntax, variable types, and object oriented programming. I know MIT Opencourseware has free course materials on learning Java, it might be a good place to start.
Need Support
Hello Guyz,
I am a newbie. I just published my first android app in Google Play Store. I need your support to grow...please help me grow. Rate if you like this game:
play.google.com/store/apps/details?id=com.hachi72.flynofly
Thanks
Adding to flywheels, next you might want to check Android specific materials from official web-site. You need to learn base/fundamental, I believe this is why you stuck with Content Providers.
Hi everyone,
some days ago, i was substancially forced to join an Android project by my professor.
The fact is that his course was about C++ (your equivalent of that course should be Compuer Science II, and i have a good knowledge of C++), and this project is in Java. I have a little experience in Java (in fact, one of the courses that i am attending is focused on Java). Now, i think that in order to be a Computer Science engineer i have to fit myself to the situation ( i have some docs about the project) but i have no experience in Android app development and a very little knowledge of XML, so i ask you some help :good:.
What i have to do is to realize some GUI for his application. It is not very difficult, but i have no idea about from where i have to begin. In these 2 days i have managed to start some very simple application from Eclipse on my smartphones, but that's all, nothing more. So, is there any book or (better) some short guide or video to follow?
I use, as IDE, Eclipse (because i usually use it for Cpp, but some people said me that Android Studio should be better). I know that Eclipse is a really god IDE (For Cpp i tried also CodeBlocks, VisualStudio and Netbeans), but i know too that it raises some error that newbie user could not managed to solve easily: one of them is a java.lang.nullPointerException raised in every main.xml file...
Moreover, the project has to connect to a IBM Bluemix-stored database.
Last but not least please share a comment about my English (that, i have to admit, is not very good). I would really like to know how it - really - is.
(Excepting the typo in the thread title).
So, i ask you to kindly share resources (video, guides ...) about realizing GUI in Android.
Well first i'd recommend using android studio since it is the official ide for android by google, and I have worked with eclipse for 2 years and the android plugin is just too buggy.
About designing the ui it is usually done in xml rather than in code since its more intuitive and there is a preview.
You should start learning the basics and from there they teach you how to design the ui.
Try the official guide in the google developers section for android "developers android training"
Are you talking about https: //developer .android.com /training/index .html ?
Yes exactly, they have some nice guides there.
Here is a very nice guide for creating your first app in Android Studio: http://www.raywenderlich.com/78574/android-tutorial-for-beginners-part-1
Here is a layout tutorial: http://code.tutsplus.com/tutorials/android-user-interface-design-layout-basics--mobile-3671
Here is a compilation of Android beginners tutorials: http://www.sitepoint.com/12-android-tutorials-beginners/
If you give a more focused description of what you are trying to achieve (what are you intending to display and how do you want to display it), more focused tutorials can be suggested.
Best of luck

You can take a look at vogella web site tutorials
They have very usable tutorials, easy to understand.
Thanks everyone, i'll give a look to these resources
Do I need to learn Java to program in Android Studio? Or I can just jump straight into it? If I must learn it, can u guys show me a great way of learning Java? (I have a Pascal basic BTW).
You definitely must. Java is the main language for android development and without knowing it you can't do anything advanced.
To start learning you can use docs.oracle.com/javase/tutorial/. But learning is nothing without practice so start your own project and use Java in it. It's relatively easy language so you can start quickly.

You are welcome. To be honest I don't know any video tutorial and personally I think the best way to learn programming is practice. So just use any Vogella's tutors and code your apps but always try to make them more complex.
Java is important for Android studio
Yes, you need to learn Java properly before visiting android studio.
Because Java is key to do programming in android studio for Android developers.

I learned from a YouTube series called "mybringback" 5 years ago. It's still a good place to start. Also, a great website that interactively teaches you to code is Codecademy.com. They are mainly a web-development website, but recently added java to their courses. It may be worth trying as well.
Root it and boot it!
Current device: Asus ZenFone 2 (Z00AD/ZE551ML)

I have collected many good tutorials for Java and Android here.
Hope it helps
It best to learn Java, but today you can also use Xamarin to develop cross platform apps using .net (Visual Studio 2015).
java is main language to android studio
if you are using android studio, Java is a must. But you don't have to learn core java, you can just jump in to android programming, coz there are lots of different library there.
i would suggest using android studio instead of others, beside they are free, they are directly from google
Yes, java is must in order to develop android apps. Android virtual machine runs java codes. So android apps needs to be in java.
Now a days, there are so many frameworks and tools available which allow you to develop android apps in other languages and convert the apps developed in other languages to java code to deploy and run on android.
I think it is a good idea to directly code in java as you can easily understand concepts involved in android os and develop apps that perform well proving best user experience.. It is not difficult to learn java and android framework to develop android apps.
As others have pointed out, yes you must. However, if you have Pascal/Delphi background, that helps a lot! So loops/ifs/functions are no stranger to you. You "only" need to learn about classes, interfaces and such stuff, not very hard.
Luckily for you, there's literally thousands of Java tutorials, books, videos, anything you can think of. I always like to stick with books from respected authors and/or the language authors. So for Java, I'd go with https://docs.oracle.com/javase/tutorial/java/nutsandbolts/index.html (just an example, there's tens of other valuable books/tutorials).
