The program now launches a thread that does all calculations but only returns strings and a bitmap used. During that time a indeterminate progress dialog is shown displaying "Calculating." When the thread completes the task then an empty message is sent the handler which then updates the views in the layout and dismisses the progress dialog. Works great.
