[Android] [IncognitoReauth] Add check on activity type before accessing
start surface supplier.

M103 merge, approved at crbug.com/1325331#c14

Currently, we are referencing the mStartSurfaceSupplier.get() to get
the TabSwitcherCustomViewManager without checking the underlying
activity type. The mStartSurfaceSupplier.get() can return null for
activity type other than Tabbed type.

This CL adds a check on activity type before referencing methods
from start surface.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure .

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.
