Rejeter la réinitialisation sur une classe ayant échoué précédemment dans OkHttp

Question

J'essaie de télécharger une image sur mon serveur en utilisant flask back end qui gérera le fichier à enregistrer dans un dossier et OkHttp dans Android. Mais je reçois cette erreur dans Android:

Answer 1

En lisant le message d'information, il me donne une idée de ce Conscrypt et a fait une recherche et a découvert que je dois installer conscrypt sur mon gradle.app

implementation 'org.conscrypt:conscrypt-Android:2.2.1'

et il fonctionne.

Answer 2

OkHttp est compatible avec la bibliothèque de sécurité Conscrypt, mais son utilisation est facultative. La trace de pile est effrayante, mais je pense que c'est juste un avertissement vous indiquant que la dépendance Conscrypt n'a pas été trouvée. Dans ce cas, OkHttp devrait revenir à l'implémentation TLS par défaut de votre plateforme.

De README d'OkHttp :

OkHttp utilise l'implémentation TLS intégrée de votre plate-forme. Sur Java OkHttp prennent également en charge Conscrypt, qui intègre BoringSSL avec Java. OkHttp utilisera Conscrypt s'il est le premier fournisseur de sécurité:

Security.insertProviderAt(Conscrypt.newProvider(), 1);

Bref, si vos requêtes réseau fonctionnent, il est probablement sûr d'ignorer cette trace de pile.
