Please I will need a help on the kind of design I chose in order to implement a job.
I am developing a large application for mobile phones and i am using the LWUIT APIs.
From decoupling perspective, I have decided to break the implementation of every of my operations into a classes, implemented in a Form class (LWUIT Form); i.e. I use a form for specific operation, and from a form calls on another form, and frm there calls another, and so on.........
I always call another form from a form, base on the operation to perform, for example;
1. I always have my class declared like this.......
2. I always transfer controls or call another class/Form like this......
My concerns here is this, since there is no way to close/end a Form,
Will these Forms that are loaded after the other remain in the memory?
Will each of the call/invocation of Forms (or their constructors), be called in a stack (just like the normal method invocation)?
I am writing an application, and half way into the development i already have 30 classes, i hope if a user has to perform operation for a long time, the application will not crash?
What could possible be the best practice in this case?
You may do the following to ensure that, at any point in time you have only one form loaded.
* Collect data from the current form
* Store the contents into a bean
* Close the current form
* Show the new form (use the contents in the bean to fill the form automatically, if required)
* Remove the bean
Not many get the right opportunity !
