How to Put a custom ArrayAdapter in savedInstanceState?

Postby Sigma » Fri Jan 07, 2011 9:54 am

I've created my own class of ArrayAdapter, ArrayAdapter<WebObject>, where WebObject is a simple class I've created.

Now I wish to send this arrayadapter into savedInstanceState for safekeeping when the user rotates the device to quicker restore the application state. How can I achieve this?
I can't find any general method to store general objects in the bundle.

Look into onRetainNonConfigurationInstance and getLastNonConfigurationInstance as they are what you are supposed to be using to deal with orientation changes. I believe it is also strongly advised that you don't store any UI related classes during an orientation change as they can contain references to the application and cause the whole application to be leaked, so be careful with exactly what you hold onto.
