Notify a User if Exception happens not in Activity class <p>My <code>Activity</code> holds a member <code>member_one</code> which holds another member <code>member_two</code> which can throw an <code>Exception</code>. I need to show user a <code>Toast</code> if this <code>Exception</code> happens. In order to show a <code>Toast</code> I need to throw <code>Exception</code> from <code>member_tow</code> to <code>member_one</code> and then from <code>member_one</code> to my <code>Activity</code>. This approach leads to big changes and I don't want to do so. May be I just think wrong, is there any easy way to handle the exception?</p>
