Improve android version detection

It is important to detect when crash stack
originates from Android 11 or newer because
newer versions are shipping a fixed unwinding
library. Older versions were producing stack
dumps which required PC adjustment, but
this was fixed in Android 11. If we apply
PC adjustment to a newer stack that
makes it meaningless.

Thus we add a heuristic to detect Android >=11
based on the app installation path.

Tools used by Dart's continuous integration (CI) testing infrastructure.

The repository is based at It is mirrored to Do not land pull requests on Github.

Results Feed

The results feed is an angular Dart application that displays changed results from the CI and from CQ runs (tryjobs). The code is in the results_feed directory. It is deployed to, using Firebase hosting.

Cloud functions

The automated testing of Dart on the CI and CQ publishes results to Cloud Pubsub, and cloud functions triggered by those Pubsub messages process the data and store it in Firestore. These functions are located in the functions directory, and are deployed on the dart-ci Google Cloud project.

Github Label Notifier

Internal users get automatic notifications of new GitHub issues created in certain repositories, by subscribing to issue labels on those repositories. This tool provides a UI for internal users to subscribe to their chosen issue labels. That UI is hosted at It also defines cloud functions that are triggered by GitHub webhooks and use the issue label subscriptions to send email notifications using SendGrid.
