An Application Not Responding (ANR) error occurs when an Android app becomes unresponsive. The ANR Analysis dashboard in Log Service visualizes user impact trends, exception trends, and specific exceptions. This helps you quickly analyze the impact of ANRs and identify their root causes.
Prerequisites

Log on to the Simple Log Service console.

Trend analysis and comparison
The ANR Analysis dashboard uses line and bar charts to visualize key metrics, including the number of affected users, affected user rate, exception count, exception rate, and exceptions per user.
When you set the time granularity to Day, clicking a data point on a chart opens the Exceptions list, showing all exceptions for that day.
You can also compare ANR data across different app versions and time ranges. The time ranges for comparison must have the same duration, such as one day or one month.
Top exceptions
After you select an app version and a time range, the dashboard displays exceptions sorted by Affected Users, helping you identify the top ones at a glance.
You can also filter exceptions by criteria such as aggregation dimension, status, and assignee.
Exception details
In the Exceptions list, click an exception to view its details.
- View the main stack trace along with key information such as the app version, number of affected users, exception count, and exceptions per user.
- View the number of affected users and the exception count within a specified time range.
- Data is ranked by dimensions such as device model, OS version, and app version, helping you quickly identify common patterns.
- Examine the crash report logs to find the root cause. The logs provide detailed device information, app runtime information, and the core crash stack to help you analyze the code.
