android: showing a progress dialog

Question

I have looked at the Android API and other posts here on stackoverflow, but have not been able to figure this out.

My app downloads files to the sd card. I would like to pop a "loading..." dialog while the file is downloading and then have it disappear when the download is finished. This is what i came up with using the android API:

ProgressDialog pd = ProgressDialog.show(this,"","Loading. Please wait...",true);

//download file

pd.cancel();

however the dialog doesn't actually show. when i debug it, it claims that it is showing, but it is obviously not on the screen.

what can i do?

Answer 1

You have to run the download code into a separated Thread. The easy way is to use AsyncTask
