ProgressDialogs and material design spec

Question

From this comment:

ProgressDialogs are a bad pattern, and are not even mentioned in the material design spec, which is why I haven't backported them.

Can anybody tell how to show my app is doing network transaction with material design spec ?

Answer 1

I think an Activity Indicator would be most appropriate here, unless you implement your own design.

Activity indicators are for operations of an indeterminate length. They ask users to wait a moment while something finishes up, without getting into specifics about what's happening behind the scenes.

This comes straight from the Material design spec, the Gmail application uses the Activity circle while loading it's data.
