Apps Starter questions....

[TickTockRob]

Hello, everyone,

I'm looking to start developing an android application in the near future - I'm currently designing it and thinking just what I want to do first.

However, I do have a couple of questions in the meantime:

1. Pricing
   Is there a knowledge bank of just how to price applications, when to use free versions, and how free versions with adverts compare to paid versions with no adverts by way of which one makes the most money?
2. Databases?
   I'm a database programmer by nature, and want to create records of data for users to relate stats and other info to users of my apps. I believe you can use MySQL with Android - is there an alternative to this, or is this a good way to do things?
3. Android Versions/Platforms
   Is there a specific way to develop for Android to cater for all platforms (tablets and phones etc) as well as versions of Android? What is the best way to cater for these variables, or is Android flexible enough that an application will work on all platforms and versions?

Thanks for your help! Apologies if I missed the answers elsewhere - if you could point me in the right direction to any answers or useful websites, that'd be great.

Also, if there's any more information that you think I'd find useful, please don't hesitate to let me know.

Thanks in advance!

hello,

I don't have any statistics about payed apps etc but i do know android supports SQLite3.

As for the compatibility of your app, android has many features to help you and is backward compatible but you'll have to account for every screen size/ heap/ density/ hardware /etc when writing your code. (in an easiest way than what i wrote might look!)

good luck

The only time you need to take screen size into account is when your layout is relative, which means when something in your layout is set to be at a exact point.
