Les nouveaux plots de la console développeur de Google ne sont plus corrects Les traces de pile ne sont plus précises

Question

Google a récemment mis à jour la console Google Play, et les plantages sont désormais automatiquement signalés.

Depuis presque toutes les traces de la pile, je suis arrivé ne sont pas plus précis:

• La trace de la pile est pleine de <OR> méthodes, donc je suppose que complète des candidats possibles?
• Tous les numéros de ligne sont 0

Notez que j'utilise Proguard (et non Multidex) et je soupçonne fortement qu'il est la cause du problème.

J'ai corrigé ce bug et la question était dans la méthode getItemViewType et non dans le premier affiché un (getItemCount). Donc, ces traces de pile sont vraiment inutiles par rapport aux précédentes. Vous savez qu'il y a un bug mais vous ne savez pas exactement où cela se produit.

Avez-vous rencontré les mêmes problèmes? Est-ce que quelqu'un sait comment le réparer?

Answer 1

Je pense que c'est parce que retrace proguard ne peut pas identifier sans ambiguïté le cadre de la pile lorsque les numéros de ligne sont omis (voir https://www.guardsquare.com/en/proguard/manual/retrace#without). De ces documents, il semble qu'il est nécessaire de conserver LineNumberTable afin de supprimer l'ambiguïté.
