Android Mobile Example - Troubleshooting Performance Issues with Sentry - File I/O on Main Thread Issue - Ecommerce App Example

**Sentry will capture span and operations details, due some pattern matching against those details, and identify performance issues in the app. Sentry will automatically detect and classify 15 different types of performance issues. Here is an example common on mobile.**

**Senty shows you the offending operations that are related to the performance issue. Use breadcrumbs with the timeline of events leading up to the performance issue.**

**Let's look at the full event, not just the problems spans identified by Sentry.**

**Sentry will show you a deeper, waterfall view of the full event with the time spans for all the operations in the event.**

**Sentry allows the developer to quickly expand back out into the transaction summary view**

**Sentry is providing the developers with helpful insights . Sentry highlights the suspect spans" (spans that consumed the most time in the transaction)**

**Sentry highlights suspect tags, or characteristics of the issue, that correlated to the performance problem - device, release, user, version name.**
