This pull request introduces a new method for detecting Application Not Responding (ANR) events by utilizing the
ApplicationExitInfoAPI, available in Android API level 30 (Android 11) and above. By leveraging this API, the Backtrace Android SDK can more accurately and efficiently detect ANR events, enhancing the reliability of application monitoring.Key Changes:
ANR Detection Enhancement: Implemented ANR detection based on
ApplicationExitInfo, improving the accuracy of ANR reporting on devices running Android 11 and later.Backward Compatibility: Ensured that the existing ANR detection mechanisms remain functional for devices running Android versions prior to 11, maintaining broad compatibility across Android versions.
Code Refactoring: Refactored relevant components to integrate the new ANR detection method seamlessly, enhancing code maintainability and clarity.
Benefits:
This update provides developers with more precise ANR detection on newer Android devices, leading to better diagnostics and application performance insights. The integration of
ApplicationExitInfoallows for a more standardized approach to ANR detection, aligning with modern Android development practices.How It Works
Now, users can choose their preferred ANR detection method. The Threshold method detects ANRs by monitoring the main application thread for freezes, while the ApplicationExit method relies on events from the Android API.
When using the ApplicationExit method, a background thread is spawned to process ANR events. This thread retrieves all recorded events, checks the last reported timestamp stored in
SharedPreferences, and evaluates each event's type and timestamp. If an event has the typeREASON_CRASHand its timestamp is more recent than the last recorded one, it is sent to the Backtrace API. Once sent, the timestamp is updated inSharedPreferences. After processing all events, the background thread terminates.Docs PR: saucelabs/sauce-docs#3160
