My recommendation, however is if you don’t want to use a two dimensional array for the map, as it may be dynamically changing, to use ArrayList<ArrayList for it, as you’ll need to get a lot of elements by index. You won’t have to bother about indexing and moreover the HashMap isn’t designed for this case – you don’t get anything for the additional space it will require.

thats a nice one…helped me a lot…

but could u please give some idea on custom map not google map…

thanks

To make it smoother is one topic on the next two parts.
I’m in the final week in my current semester. Please give me the time

Very nice tutorial, this helped me a lot! Keep the good work up!

Can’t wait to next one but i need some help.. pretty new to this! How do you implement a whole background? Or do you need to it for every cell?
And any tips before the next tutorial, how to do it smoother?

Thanks!

very nice and useful tutorial. Although rendering the complete scene, this is very useful. Can’t wait for the next tutorial part, showing of how to do with 200×200 cells

Just mail me, if you’re going to do so!

your right, my conventions are from the j2ee projects where I learned Java. We had Checkstyle installed to check that every variable has its prefix _
Currently I “learn” to use the m prefix, which is defined by the Android Style Guide.

This is probably needlessly confusing to beginners, looks kinda ugly to be honest, and more importantly goes against Java’s naming convention. The following comes straight from the official site:

“Variable names should not start with underscore _ or dollar sign $ characters, even though both are allowed.”

It’s probably just a bad habit, but habits are made to be broken.
