optimising my app

[ashwin.nath.m]

hi
My app have around 20 different thread classes as innerclass of my main midlet class
each of them does different network operations(no two of them are called simultaneously).

i read in wiki "reduce number of classes in app, Can get away with 2 classes: one MIDlet class and one Canvas class. "
and also
"Create a background thread in startApp() and reuse it. "

So can i create one bg thread and use in my case.
how do i create this bg thread?

also now now my canvas is a innerclass of midlet class. does this have any performance prblems?
Thnks in advance

hi ashwin

This is not right way to develop application because latest Phone may support 20 thread in your application but your application in most phone will not work properly so first reduce your number of thread in your application

thanks

In what way do you want to "optimize" your app? You want to make it smaller? Faster?

You say you have 20 thread classes, but how many threads do you actually run at one time?

Reducing the number of classes helps to reduce size, but I don't recommend you do this unless you need to make the application smaller (for example, if you need to install on a device with a small JAR limit).

Avoid inner classes unless you have a very clear reason to use them. It's almost always better to use separate classes than inner classes. It is easier to manage separate source files, and it is easier to manage the connections between classes. Don't use inner classes simply to avoid passing a parameter, or implementing getter or setter methods. In particular, avoid anonymous inner classes.

i dnt call any two of them together.
i want them to run independent of my main app thread. that's y i created seperate ones for each task

hhmmm ok.. but do you mean that when you call a new Thread there is no other Thread (even of another class) running ?
