Download-Manager für Audio fehlgeschlagen ⇐ Android

[Anonymous]

Wenn ich ein Lied von Webview herunterlade, wird es in den Ordner heruntergeladen, aber es ist nicht erfolgreich und ich kann es nicht anhören. Ich verstehe nicht, was falsch ist. Ich habe die URL selbst festgelegt, um sicherzustellen, dass sie korrekt ist.
API ist 36
