Those dark spinning progress dialogs in the Amazon and Engadget apps - are those standard in Android?

ProgressDialog dialog = new ProgressDialog(MainActivity. this); dialog. setMessage("Your message.."); dialog. show();
ProgressDialog is a modal dialog, which prevents the user from interacting with the app. Instead of using this class, you should use a progress indicator like ProgressBar , which can be embedded in your app's UI. Alternatively, you can use a notification to inform the user of the task's progress.
The Dialog class is the base class for dialogs, but you should avoid instantiating Dialog directly. Instead, use one of the following subclasses: AlertDialog. A dialog that can show a title, up to three buttons, a list of selectable items, or a custom layout.
It's a ProgressDialog, with setIndeterminate(true).
From http://developer.android.com/guide/topics/ui/dialogs.html#ProgressDialog
ProgressDialog dialog = ProgressDialog.show(MyActivity.this, "", "Loading. Please wait...", true); An indeterminate progress bar doesn't actually show a bar, it shows a spinning activity circle thing. I'm sure you know what I mean :)

Today things have changed a little.
Now we avoid use ProgressDialog to show spinning progress:
If you want to put in your app a spinning progress you should use an Activity indicators:

Thay have renamed the component to Progress Indicators now.
