question: @ VisibleForTesting void recordFailureReasons ( Context context ) { int reasons = FailureReason . bitValue ( failureReasons ( context ) ) ; mFailureReasonsToRecord . add ( reasons ) ; if ( LibraryLoader . isInitialized ( ) ) { Integer reasonsToRecord ; while ( ( reasonsToRecord = mFailureReasonsToRecord . poll ( ) ) != null ) { RecordHistogram . recordSparseSlowlyHistogram ( "Precache.Fetch.FailureReasons" , reasonsToRecord ) ; RecordUserAction . record ( "Precache.Fetch.IntentReceived" ) ; } } }
target:  Tries to record a histogram enumerating all of the return value of failureReasons(). If the native libraries are not already loaded, no histogram is recorded.
