Application Design Approach

[Sj Yard]

An app is being developed.
What is the best approach to proceed before starting?

Method 1:
- flow chart
- have all Layouts designed
- code all .java files
- link them all in manifest


Method 2:
- flow chart
- have all layouts designed
- code one .java and link it in manifest and then move on to coding the next .java


Method 3:
- flow chart
- first layout designed -> .java coded -> link in manifest
- second layout designed -> .java coded -> link in manifest
- repeat

Please advice which is the best approach.

IMHO, it's best to get a few smaller pieces working front to back, then move on to the next piece, rather than building one whole layer before moving on to the next layer. Then once you've got a couple pieces proven out vertically, you may want to go flesh out larger chunks of a couple of lower layers before doing more end-to-end work. I find that alternating between vertical and horizontal work helps me keep a more holistic picture of the project in mind and also helps flesh out design problems and stuff I just plain didn't think about sooner rather than later, which makes them easier to fix.

Note that I'm talking about software development in general, not Android in particular.

My approach has always been the "Method 3"

Code all java files separately and link them in the manifest
