Prerequisites for Android Development

I really like doing Android development and over the past few months I’ve done quite a bit of it but I found at the beginning that some things didn’t seem to be entirely logical that were quite important despite the fact that I already had a vast programming knowledge. Here is a list of things I reckon are useful for learning Android development:

  • Java experience: I don’t think that you need to know loads of Java to develop Android apps but I would say it is important that you at least know the syntax and roughly how to do things. Experience in a similar language like C# or C++ would probably get you by, just so long as you know the difference between a package, class and that kind of thing
  • Experience in another object-orientated language: Some experience in another language would also be useful because despite the fact that most Android development is in Java it is useful to understand how other languages do things because a lot of the Android specific Java has had influence from C++
  • An understanding of how apps work: This would probably come with programming experience but you really aren’t going to get anywhere if you don’t get how the most basic apps. Reading a few tutorials can help fix this
  • Experience creating user interfaces via code and and a visual designer: Android uses both XML layouts and pure Java code to create User Interfaces so provided that you have done something in both before you’ll probably be fine. I should imagine that it would probably be OK if you’ve done JavaScript DOM and HTML
  • Basic knowledge of XML and SQLite: You won’t need to know how to do these perfectly but so long as you can create XML documents and edit them. I wouldn’t say SQLite knowledge is vital but it would be good to have some database knowledge
  • A basic understanding of other mobile platforms: I had done a tiny amount of iOS and Windows Phone development before starting Android which probably helped me a tiny bit because it gives you some knowledge of design. Windows Phone development is probably more different to Android than iOS, so even if you’ve just created a calculator in iOS you’ll be in a good position to start Android development
  • Good resources for testing: The emulator is good but I’ve found that it always useful to either have at least one Android device for testing. I also recommend setting up a few different devices in the emulator with different screen sizes and versions of Android because that will give you a chance to test in loads of different environments
  • You’ve read some stuff on Android development: It is worthwhile reading up on Android development before you get started. Android Design and the Android Guide are both good places to start and reading some blogs will probably help develop your ideas. If you get stuck, make sure that you go on Stack Overflow.

Once you are fairly confident with all of this I recommend going over to Lars Vogel’s site which has some great development tutorials.
