I would like to know what are the best use cases for Content Provider and what are not .

Is there any alternative for content provider now.

If you need to share streams or two-dimensional data sets (rows and columns) across processes, ContentProvider is a fine solution.

ContentProvider will not get stains out of your clothes, nor will it bake a cake.

An alternative for doing what?

In Gmail, When click on Attach file option-> it shows files present in the file system to select and selected file gets loaded . I want to know how this scenario implemented using Content Provider or anything else

I am uncertain what “this scenario” means.

If you mean that you want to do what Gmail is doing, Gmail probably is using ACTION_OPEN_DOCUMENT, or perhaps ACTION_GET_CONTENT. You will find ACTION_OPEN_DOCUMENT (in the form of ActivityResultContracts.OpenDocument) covered in Elements of Android Jetpack.
