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 patrickwilliamallen@comcast.net

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
