How do I check for errors or log errors in release version of my app?
Activity crashes the app in release version but working in debug version. How do I check for errors?
You have a few options before you:
1. If your app is already live, then the Play Store records all exceptions thrown by apps on connected devices. Log into your Google Play Store account and see here.
2. If you need even more detail, the Google Play Services library has deeper support for crash analysis than what you normally get from the Play Store. See here.
3. You can add a support package like Crashlytics that will provide real-time crash analysis for apps in the wild.
Log.wtf() emit log messages even in release mode, and can be observed in the Logcat.
