How we reduced an Android app's crash rate by 33% and ANR rate by 69%
A focused Android stability effort reduced the app’s user-perceived crash and ANR rates by 33% and 69%, respectively.
Case studyOn this page3 sections
An Android app was recording user-perceived crash and ANR rates above its stability targets. NetForemost analyzed the main causes, prioritized the issues with the greatest user impact, and implemented targeted fixes that reduced both rates substantially.
Stability is part of the mobile user experience. Unexpected closures and Application Not Responding (ANR) events interrupt use, making crash and ANR rates important indicators of product reliability.
The goal was to find the main causes of those incidents and focus the work where it would have the greatest impact on users.
Finding the highest-impact issues
NetForemost analyzed the primary causes of instability in the application and prioritized the problems with the greatest user impact. The team then implemented targeted fixes for the most frequent crashes and optimized the app's behavior to reduce ANR events.
The result
The user-perceived crash rate fell from 0.54% to 0.36%, a reduction of about 33%. The user-perceived ANR rate fell from 0.84% to 0.26%, a reduction of about 69%. Together, these improvements reduced interruptions during use and gave Android users a more stable experience.
