sealed class KnownIssues

List of all known issues reportable by BackportedFixManager.

These are critical issues with fixes that are backported to existing android releases and are reasonable for app developers to guard a code block with []BackportedFixManager.isFixed].

Each known issue includes sample usage.

The id and alias of a known issue comes from the list of approved backported fixes in the Android Compatibility Test source directory cts/backported_fixes/approved.
