Answer 1

May be this will helpful. You have to make a background operation using thread concept like AsyncTask. Using this you can hide the actual work from the UI part. And AsyncTask will get unallocated after your operations are completed.

• Create a subclass of AsyncTask
• Use AsyncTask to do background work
• Call onPreExecute() to initialize task
• Use a progressbar with setIndeterminate(true) to enable the indeterminate mode
• Call onProgressUpdate() to animate your progressbar to let the user know some work is being done
• Use incrementProgressBy() for increment progressbar content by a specific value
• Call doInBackground()and do the background work here
• Catch an InterruptedException object to find end of background operation
• Call onPostExecute() to denote the end of operation and show the result

Answer 2

I find the name a bit misleading, but you should show a ProgressBar while background operations conclude.

Answer 3

You can use a ProgressDialog whit a Handler.
