I'm developing an Android game, and I'm making it so that it can run on low end devices without GPU, so I'm using the 2D API. I have so far tried to use Android's mechanisms such as layouts and activities where possible, but I'm beginning to wonder if it's not easier to just create a single custom view (or one per activity) and do all the work there.

Here's an example of how I currently do things: I'm using a layout to display the game's background as an image view and the square game area, which is a custom view, centered in the middle.

What would you say? Should I continue to use layouts where possible or is it more common/reasonable to just use a large custom view? I'm thinking that this would probably also make it easier to port my code to other platforms.
