Hi all,

I'm trying to port an old c/c++ program of mine to the Java/Android world

and I need a few general suggestions.

My app has a static array (say 2Mbytes) which on

start has to be preprocessed to build a working array

of about 40Mbytes.

The app has just two text field (one for input, one for output)

and a start/stop button(s).

The user enters something in the input field, press Start and

the app perform an intensive computation on the large array

and produces an output.

If the computation takes too long, the user can press Stop

and start again.

Which is the best way to structure this kind of app in Java for Android?

Should I use an Activity for data preprocessing and graphic interface and

a Service for computation (to which I must pass a reference to the large

data structure) ?

I just need some general advice. 

(If this is not the right group for this kind of question,

please suggest me where to ask.)

Thanks,

Giovanni
