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.

In my opinion, the best way for not a game development is using Xamarin platform. Xamarin is pretty good, but it's not a free.
All I can provide is the hard way : stick to a place like stackoverflow.com + the android official documentation.
You'll find tons of content relating to your question ; I'm sure about that.

The offical Android Tutorials are a great place to start.
I've found that if you start by trying to build something that you have in the past but target it at Android you'll learn a lot about the framework, its quirks, and how to do things maybe a little bit better than what you'll sometimes find on various sites. I second that Android's docs and tutorials are a great place to start, but you could take them and piece something together right from the start. It's also a great way to see how your project will work and perform on a real device running the Dalvik or ART VM FWIW, you'll notice that things will perform MUCH better with ART.
If you are a window coder, using java or c# is easy for transform, so download android studio or xamarin, open examples and do again.
If sqlite (default in android is not enough with you) you need create app with client-server app

I've done quite a bit of software development in my career, though very little has been recent, and none has been on a mobile platform. But I find myself in a situation where it would be useful if I could write a simple web app for Windows Mobile that for the most part just wraps a UI around a set of web services calls to an external server.
So, some questions:
1) What languages and/or dev environments would best support this kind of effort? In other words, how can I make this simple rather than difficult?
2) Are there free, open-source tools that would support this?
3) Are there useful open-source libraries that would simplify my task?
4) Is Java an option?
I imagine that there are several, perhaps even many, options that may be open to me. But I really have no idea where to start. So if anyone here can point me in a useful direction, I'd greatly appreciate it. Thanks!
This stuff used to be in a sticky at the top of the Dev/Hack section, but they have had a massive sort out and put it all in the wiki instead.

Thats where I'm at...
I'm going to learn java then transition to android with the end-result being an app developed for android. I don't think it will be a difficult app to develop. A database with a front end GUI for data entry and retrieval with export and backup options. Nothing flashy or fancy, but nothing that currently exists fits what I want it for the way I want it. I would like to have it done by the end of the year working around real life.
I am completely new to Programming. More of a power user, but that is where it ends... I am a complete user.
I bought a book called Java 7 for absolute beginners by Jay Bryant (ISBN 1430236868)... Can't link to it because of anti-spam rules. Don't know if it will help.
What are some other books (I can't learn with e-books... I do better with a textbook) that the experts here would recommend?
Java is good, but you also have to learn all about the Android system.
This includes activities, providers, cursors, listviews and any number of things that are not in your Java book.
The usual mother lode for Android documentation is the, um, Android documentation!
http://developer.android.com/reference/packages.html
Short advice on how to write your app (pretty much standard advice for anything at all DB related).
Write a provider for your information that is backed by an SQLite database.
Write an activity that queries this and uses Cursor and CursorAdapter to fill a ListView.

I wanted to learn the programming language basics before throwing android into it.

I appologize if this is a dumb question, but I am new to app development, altough some experienced in php/html.
I want to create an app where user fills in forms. The app development is easy to find info about, but i also want a back end plattform where I read the submitted forms and organize users.
So, my question. Is there a sort of ready wordpress like plattform to customize, or should this be built from scratch? If so, which platform is the best?
One note I should add about Buddy (full disclosure: I work there) is that we maintain independent instances of the platform in different locations around the world. If you need to host your backend in Europe (for response time or data sovereignty reasons, for example), you can choose your app backend to be sandboxed in the EU. Likewise the US and likewise China (with Brazil, Singapore and Australia coming soon).
he best way to develop mobile apps is to use REST services. So now you can choose any thing.
Any language that can used for server side programming can be used.
Now it is up to you choose the language.
If you familiar with JavaScript then you can try nodejs. You can make small app server in it.
But if your server software design is very complex (containing threads and synchronisation) then java can be handy.
But there is no restriction of language.
Firebase should be also a way to go for this.
The best android back end services include, Parse, Kumulos, Kinvey, backendless, QuickBlox.
Concerning the forms where users can fill up information, would something like help out?

On Apple's platform you might need an iPhone developer - it is quite possible to create and publish an iPhone app using your form.
I did take the help of mobile apps development service in toronto to know the process which is described here: http://support.brightcove.com/en/app-cloud/docs/step-step-guide-publishing-apple-app-store-using-mac
Thanks Carol for sharing such a wonderful article.

I have heard good things about Hasura (Not affiliated in anyway). And I think parse - mentioned above - is no longer available.
I'm wondering why nobody mentioned Google CLoud or AWS. They are most mobile friendly for a good price
Hi, if you will decide to build from scratch, there are different options/frameworks. But If you use kotlin you should look to Ktor.

Hello Guys & Gals
I'm a SEC student and i have a lab to do with these conditions.
1.Decompile an app
2.Add an AccessibiltyService to it
3.Check if the user has app1.example, app2.example
4.Use ViewTextChanged event like a keylogger to grab the named apps data.
My Solution was
1.I've done it via apktool, that was easy though.
2.First i've decompiled it to Java via Jadx and i've got tons of errors, then i thought it's better to create an AccessibiltyService outside that app, compile it to smali and inject it to the app, next.
these are some related articles
