Breadcrumbs are the events leading up to a crash in your monitored mobile app. Aternity Mobile SDK captures these events and reports them after you restart the app after the crash. You can view the breadcrumbs for each crash in the Crash Details dashboard.

Monitored apps collect several breadcrumbs by default, including the launch time of the app, the timestamp when the app was last in the foreground, the timestamp when the app was last moved to the background, and the names of the last 20 screens shown in the app since its launch. As a mobile app developer, you can also create your own customized breadcrumbs by inserting leaveBreadcrumb() in the source code, with your custom text message to later help troubleshoot the cause of the crash.
