Question

I’m wondering how to handle sub processes with the back button in mind.

For example:

1. Skipping the login screen when clicking back from the default view
2. Pre-upload processing view. I want the back button to return to the last activity before the upload after the user uploaded or canceled.

I imagine the solution will include overriding the finish() behavior, I’m just not sure about the details.

Help will be appreciated.

Thanks

To prevent a previous Activity from appearing when the user uses the back button you should use the noHistory manifest flag.

I suggest you read up on how the Activity backstack works in more detail. This guide should prove useful:
