Developing first Android app - Android Q&A, Help & Troubleshooting

Hello
I have recently completed Android (Beginners) course on Udacity and have learned how to create simple stand-alone apps. However, I want to design a simple android app that briefly does the following:
1- Asks the user to login/signup
2- User is shown an Image of the area (like Google Maps)
3- When user taps any part of the image, other users who are nearby are given a notification.
Hence, I am now confused about what to do next? I intend to learn the required topics on my own, but I don't know where to start and what topics to learn.
I have great programming experience, and am familiar with Java too.
Regards

[Q] Any good books for Android Application Development?

I'm a C# developer by profession and have dabbled in Android application development in the early days of Android (prior to Eclair). At the time, I followed the Google Tutorial, various websites and bought a couple of books. However, I felt there were some things lacking explanation to fully understand how things worked. I've recently had the interest to revisit it. I know there's the Xamarin software that will allow me to develop Android applications using C# and Visual Studio but I was keen to stick with Java code and Eclipse. I know the Google Tutorial has been updated but a brief look at it still seems to show there's not enough explanation behind certain aspects.
Can anyone recommend a good book that takes you through a real and working Android application which has good explanations for things along the way?
TIA

[Q] How to start coding

Hello, everyone. Can someone please direct me, an absolute beginner with no experience in programming at all, where to begin learning. I would like to ultimately develop for Android.
I'm running Ubuntu 13.04; how can I set up an environment to learn programming, and what are some resources that I can use?
Install jdk on the comp then on your phone download the app learn java in 24 hours it walks you thru making your first program so you get the basics
Hello, I'm pretty much in the same boot as the OP.
I'm working in the medical field and get bored of not having the app I need to ease up paperwork, so I decided to make them myself.
However, exept a hangman game in high school I never coded. So yesterday i took my old laptop, put some Ubuntu on it, the sdk and created the famous "hello word" app.
The problem is, even in the tutorials, some thing were to complicated, so I called upon my cousin (a german develloper) and he gave me some advices.
Especially, he told me that java was maybe not the easiest way to learn to code with 0 background and suggest me to try python and other things.
Do you have advices for me, since I want to build simple app (somes textfields, somes checkboxes to get scores and the ability to export a result sheet in pdf) at first, but i do not want to use app inventor or similar tools since I ultimately want to fiddle with the AOSP agenda (get the contact list to pop up like the invite list when i click "description field" , change default duration of appointements etc...).
Any ideas, suggestions, or tutorial are welcome, just keep in mind that I know nothing (Jon Snow like).

If you want to become a professional android developer then it is advisable to learn Java and XML a bit better,,and there are bunch of resources available on How to build android apps !
If you really want to become a Programmer then it is advisable to start from the beginning i.e C and then Java
Thats how everybody starts learning coding !
Go through video tutorials for understanding how the coding works !
Happy to help !

google it man you will thousands of website which will teach u programming for free. I would have put the links but dont wanna be treated as spammer
For now don't worry about making an app with the Android SDK or anything big like that. Just start simple with some little programs that print stuff into the terminal. It's a good thing that you have Ubuntu because Linux OS's are always great to learn programming on!
I'm also a noon and I found it easy to start with Batch on Windows and I have just been getting better and better!
Well I understand it's not easy to get started. One thing you will have to recognize that there's a lot of things involved getting prepared for Android programming. For example, while developing for Android you will need to be able to write a bit of XML as well, you will need to set up your IDE, get the necessary Java dependencies, get a little bit familiar with Maven to be able to use 3rd party libraries and so on. It's most definitely intimidating. So what I would recommend is to...
- Try to allocate time every day for learning this, even if it just means half an hour or less a day.
- Always take notes and don't be afraid to ask; nobody should assume you know the answer.
- Once you've learned something, help others to get ahead - seniors will probably recognize your efforts so you will be able to get help more easily.
- Try to talk about programming in person with people who are more proficient in it. Nothing helps as much as having a pro sitting in the same room, ready to help you.
- Try to join related communities as well, it can really speed things up.
- Baby steps. Many people get started in programming with having crazy big ideas only to meet failure later. It's not a good thing to frustrate yourself, so choose small goals first.
I can't emphasize the last point enough. Whenever you start learning new stuff - no matter whether you're a novice or an expert - you will need to focus on this, because the initial steps are always problematic. For example, when you start learning a new programming language: the syntax is new, the way for getting the app run is new, the IDE might be new, if the tool is web related then probably it uses a different kind of server than the one you're used to etc. etc. etc. so barriers all around. You must get comfortable with this first, then you will be able to speed things up.
How to start coding
How I started:
Basic Stuff:
1. Java, I used Java Complete Reference
2. Data Structures (most commonly used- Stacks, Queues, Linked list, HashMap, List) [Basic Understanding]
3. Algorithms (will help you to write efficient code) [Basic Understanding]
4. XML, just basic understanding is required, use internet to learn
Android Specific Resources:
1. The Busy Coder's Guide to Android Development [Very useful]
2. New Boston Videos
3. Android Cookbook, if you want a solution to a particular problem
Spend more time learning Java and other basic stuff, once your basics are clear, then you can easily adjust yourself on any platform.
Recommendations for Aspiring App Developers
Hi,
I was in your same shoes about 3 years ago so I can tell you what steps I took to start coding. I took the longer route but it was the correct route. Key suggestion is to learn the lower levels of coding first. (lower levels meaning base languages, binary being the lowest). Start with the C language as this is the core programming language which most other higher levels are based on. If you have the money take a structured online course on Udemy or CodeAcademy. If you're short on money and need to learn on your own don't worry there's plenty of resources out there to learn. That's how I did it. Start out with videos on youtube, try to find a complete structured course here's one with over 130 videos. Sorry, can't post links cause I'm new but just go to Youtube and type in "C Programming Complete Tutorial" to get the course with the structured 130+ videos.
The best way to learn any programming language is to find some free source codes in the designated languages and start tinkering, breaking and fixing the code. Once you learn this core language you will be able to programm\ desktop apps, simple software and mobile apps in other higher level programming languages.
Hope this helps.
-Jeff

Hey Guys,
I love thenewboston website that you've pointed us to. But as a first step, should I learn some C or Java before progressing on to thenewboston Android tutorials?
I have no programming experience, but lots of motivation.
Thanks,

[Q] From Desktop to Android Development

From Desktop and Web to Android Devices : I Need Help
For over twenty years I have developed apps using Borland's Delphi and BDS development tools. I now want to migrate a subset of that functionality to Android devices ... but need help getting over the learning curve hump.
The general particulars are:
1. Master-Detail, content management. Multiple detail data tables for each master record.
2. Image gallery. See all images in the gallery or only those images which have been linked to a master record.
3. Taking a pic and linking it to a master record.
4. Ability to query for local businesses ... such as "Find <business name> within <x miles> of my current GPS location.
I currently have Eclipse and the latest ADK tools installed. Also, I have some Java experience.
Is there a place I can go to find a baseline source code framework that satisfies these requirements and demonstrates how to store and manage the master and detail data and links?
Any help would be greatly appreciated. I can be contacted at [email protected]
Many thanks, from an old dog trying to learn new tricks.

What tools should I use for development?

Hello XDA forum members.I want to be able to make my own Android applications that could work via internet.I would like to create small and simple social network with some simple functions.I'm starting with learning of programing in C++ because I always wanted to know to program in that language.But first I would like to create an application that would be used in Android.So I'm willing to learn an additional language just so I could make this idea that I have and I'm sure that I will use this knowledge in future.
So my question is in what program do you code applications for Android smartphones,what is the best way to learn it and when I learn it I want to be able to make application like Badoo(social,meeting application) Badoo is the best example of what I'm trying to do because it is downloadable application that connects to their website.Because this idea that I have will have similar interface and similar features.Please help me with your advice so I don't loose time on mistakes and trying on different languages.Thank you in advance.
Please delete this thread.It is posted in wrong section.Sorry

You are new to Android development? Consider reading this post!

Hi everyone. I want to share some resources that may helpful for anyone who still don't know where to start.
If you don't have any background, consider learning programming using Scratch or Alice. It seems just suitable for kids but actually for everyone who want to think logically.
If you have some basic background and want to have solid Java background (which I recommend) before moving to Android development, you should start with "Head First Java". They also have "Head First Android", but personally I don't like it so much.
After you have a solid Java background, you can start learning Android using this free course on Udacity. It has 5 parts that cover everything that you need to make literally any app on Play Store.
After you completed the above course, let's make your own project. You don't have to learn other courses or textbooks in order to make an app. You should try to make your own app using what you have learned with the above course. When you making your project, you will encounter real-life problems. By solving it (using Google, StackOverflow, XDA, other tech forums, ...), you will learn more than any course or textbook can help you.
I hope you will find this post helpful for you. If anyone has a question, please leave your question below
Hi, new user here. Thanks for the read
Hi,
I just signed up on this forum and came across this thread and so decided to post a question. First, i have been a full-stack developer and now working on Cloud, AI/ML but android mobile app development is new to me and i am pursuing a self-paced training. My intention is to start off by learning the basics of android and the ide, the various elements and work my way up to the advanced level. Then start learning and work on flutter. I have a fair bit of experience on Java as i have developed java enterprise and web application (JSP, applet based) in the past.
Right now, i am looking at the Android Basics to Advanced nanodegree program offered by Google on the android site, udemy, udacity, etc and lots others on the internet. just wanted your opinion which course would be a good place to start.
Thanks.
