When a user searches for a non-existing stop now, a new Fragment is created. This is fine, but if the user searches for a new stop, another fragment is created and the previous one is kept in the stack.

Final result: if the user goes back, the "results" for the previous (wrong) arrival search are shown. This should not happen.

Ideas:

• Use a temporary fragment to "hold" until arrival times are found
• Reuse the "not found" fragment
