Debugging an app crash on specific devices without writing code requires a systematic approach. Here’s how I would tackle it:

1. **Gather Crash Reports**: Utilize tools like Firebase Crashlytics to collect detailed crash reports, which provide stack traces and other relevant information about the crash. If the app is available on the Play Store, use the Play Console to monitor crash reports and analyze trends.

2. **Analyze Stack Traces**: Examine the stack traces from the crash reports to pinpoint the exact location in the code where the crash occurs. Look for common patterns or specific conditions that might be causing the issue.

3. **Device Compatibility Testing**: Test the app on various devices with different configurations, OS versions, and screen sizes using Android Studio’s emulator and physical devices if available. Ensure that the app is tested in multiple languages and regions to identify any localization issues.

4. **Log Analysis**: Review logs collected during the crash to understand the sequence of events leading up to the incident. Filter logs to focus on relevant entries and identify any anomalies or errors.

5. **Check Permissions and API Compatibility**: Verify that all necessary permissions are correctly declared and granted, especially dangerous permissions that could lead to crashes if not handled properly. Ensure that the app is compatible with the API levels of the devices experiencing the crash.

6. **Third-Party Libraries**: Review the documentation and compatibility notes of any third-party libraries used in the app. Check for known issues or updates that might resolve the crash.

7. **Network and API Requests**: Analyze network requests and API responses to ensure they are handled correctly and do not cause crashes due to unexpected data or connectivity issues.

8. **User Feedback**: Collect feedback from users experiencing the crash to gather additional context and details that might help identify the root cause.

By following this approach, I can systematically identify and address the issues causing the app to crash on certain devices, ensuring a more stable and reliable application.
