Proguard: IllegalArgumentException - Errore imprevisto durante la valutazione dell'istruzione

Question

Sto provando a creare un apk di rilascio con proguard abilitato. Sto ottenendo l'errore qui sotto. Allegherò lo stacktrace completo di seguito.

Unexpected error while evaluating instruction: 
Class  = [*] 
    Method  = [myMethod(Ljava/lang/String;Ljava/util/Map;)V] 
    Instruction = [532] aload_3 v3 
    Exception = [java.lang.IllegalArgumentException] (Value is not a reference value [proguard.evaluation.value.UnknownIntegerValue]) 
    Unexpected error while performing partial evaluation: 
    Class  = [*] 
    Method  = [myMethod(Ljava/lang/String;Ljava/util/Map;)V] 
    Exception = [java.lang.IllegalArgumentException] (Value is not a reference value [proguard.evaluation.value.UnknownIntegerValue]) 
:*:proguardRelease FAILED 

ho ristretto la questione fino a righe di codice che non è menzionato nella stacktrace.

RelativeLayout.LayoutParams relativeLayoutParams = new RelativeLayout.LayoutParams(
        ViewGroup.LayoutParams.MATCH_PARENT, 
        ViewGroup.LayoutParams.WRAP_CONTENT); 

Se devo commentare questo, proguard termina senza problemi.

Attualmente ho aggiornato la proguard alla nuova 5.0 e non ha avuto alcun effetto.

C'è qualcosa che sto facendo male?

Eccezione piena stacktrace:

Answer 1

Questo è probabilmente un bug nell'ottimizzazione dei tipi di enum di ProGuard. Si può essere in grado di lavorare intorno ad esso disattivando questa ottimizzazione:

-optimizations !class/unboxing/enum 

Se è possibile inviare una segnalazione di bug o mail me i dettagli, mi guarderò in esso.

Answer 2

soluzione Strano, ma ho trovato un modo per risolvere il problema. L'esatta sezione del codice che stava causando il problema proguard era separata in un metodo diverso e nella vecchia posizione veniva chiamato quel metodo. Questo sembra aver risolto i problemi, anche se non sono sicuro di come lo abbia risolto. Sembra sempre più simile a un bug Proguard. Funziona per me, quindi è qualcosa che altri possono provare se si imbattono in questo problema.
