Report crashes while recovering

FireCrasher keeps the app alive, but you still want every crash recorded. The onCrash handler gives you the throwable before recovery runs — log it there, then call recover(). Because the app survives, these arrive at your reporter as non-fatal / handled exceptions, not fatal crashes.

Log, then recover

installFireCrasher {
    onCrash {
        // 1. Report first, so nothing is lost if recovery itself struggles.
        FirebaseCrashlytics.getInstance().recordException(throwable)   // or Sentry.captureException(throwable)
 
        // 2. Then recover.
        recover()
    }
}

The order matters: report before recover() so the report is captured even if a subsequent recovery attempt kills the process.

Add context

retryCount (in onCrash scope) tells you how many times FireCrasher has already tried to recover this crash — useful signal on a report:

onCrash {
    FirebaseCrashlytics.getInstance().apply {
        setCustomKey("firecrasher_retry", retryCount)
        recordException(throwable)
    }
    recover()
}

Don't forget out-of-process deaths

onCrash only sees JVM exceptions on threads FireCrasher controls. Native crashes and ANRs never reach it — report those separately via the detect-native-crashes-and-anrs skill (onPreviousProcessExit).
