Something along this idea would be good.
Since I have just started programming with B4a I have written a lot of code but I do not know best practice. A lot of times I have just stumbled upon better ways to approach a coding issue by looking through other peoples code.
I am a PHP coder normally and php.net is great because they have a detailed description of each function and under that people post examples on how to use it in different situations and different ways.
