30. 2. Custom logs Logs can be useful in determining what user actions led to a crash. Firebase does well to include that as part of the error. Firebase allows you to log to logcat or onto firebase directly
31. 2. Custom logs
32. 3. Error clusters Firebase groups errors in clusters, by similar stack traces and severity
33. 4. Upload proguard mappings Firebase allows you upload your mappings.txt file to map proguarded crash logs.
34. 5. Protip - Handling reporting for development & production. Little Problem. Firebase doesn’t allow you to enable or disable crash reporting.
35. 5. Protip - Handling reporting for development & production. How to disable Firebase crash reporting for dev build? You can’t. For now.
36. 5. Protip - Handling reporting for development & production. Here’s what you can do instead: Create dev and prod flavours for development and production builds.
37. 5. Protip - Handling reporting for development & production. Create another app on the console for dev build. Add the google-services.json to the project app/src/<build-flavour>/google-services.json
