HockeyApp se bloque en appuyant sur le bouton Précédent sur Windows Phone

Question

HockeyApp se bloque lorsque vous appuyez sur le bouton de retour lorsque vous êtes invité au lancement de l'application et demande l'envoi/la suppression des journaux de plantage. Un NullReferenceException se produit dans HockeyApp; la piletrace est attachée.

La plate-forme est Windows Phone version 8.1 RT et HockeyApp est 2.2.2

Comment puis-je résoudre ce problème dans mon application?

Answer 1

Il est bug in the HockeyApp sdk. Il a été corrigé il y a deux mois avec this commit. Mais la dernière version du sdk (2.2.2) a été construite il y a 8 mois.

Vous devriez donc utiliser l'invocation SendCrashesAsync avec try { //... } catch (NullReferenceException) { } et attendre la nouvelle version de sdk.
