Ablehnen einer erneuten Initialisierung für eine zuvor fehlgeschlagene Klasse in OkHttp

Ich versuche, ein Bild mithilfe des Flask-Backends auf meinen Server hochzuladen, das die zu speichernde Datei in einem Ordner und OkHttp in Android verarbeitet. aber ich bekomme diesen Fehler in Android:

Und versuchen, online eine Lösung zu finden, um dieses Problem zu beheben, und dennoch nichts in meiner Situation zu lösen.

Beim Lesen der Info-Nachricht habe ich eine Vorstellung davon Conscryptund habe conscryptnachgeforscht und herausgefunden, dass ich auf meiner gradle.app installieren muss

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

und es funktioniert.

OkHttp ist mit der Conscrypt-Sicherheitsbibliothek kompatibel, die Verwendung ist jedoch optional. Die Stapelverfolgung ist beängstigend, aber ich denke, es ist nur eine Warnung, die Ihnen sagt, dass die Conscrypt-Abhängigkeit nicht gefunden wurde. In diesem Fall sollte OkHttp auf die Standard-TLS-Implementierung Ihrer Plattform zurückgreifen.

Aus OkHttps README :

OkHttp verwendet die integrierte TLS-Implementierung Ihrer Plattform. Auf Java-Plattformen unterstützt OkHttp auch Conscrypt, das BoringSSL in Java integriert. OkHttp verwendet Conscrypt, wenn es der erste Sicherheitsanbieter ist:

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

Kurz gesagt, wenn Ihre Netzwerkanforderungen funktionieren, ist es wahrscheinlich sicher, diesen Stack-Trace zu ignorieren.
