Question

我正在使用NextCloud Android库https://github.com/nextcloud/android-library 到目前为止，我的Android应用已成功连接到下一台云服务器。但是，在将项目更新为Android 9（API 28）之后，该库由于崩溃而不再起作用由于未加载类：NTLMScheme

我已经将旧的org.apache.http库包含在项目gradle中

useLibrary 'org.apache.http.legacy'

以及android清单中的

<application>
    <uses-library android:name="org.apache.http.legacy" android:required="false"/>
</application>

在该应用中，我根据此旧版库使用其他云（Google Drive API，Dropbox API等），并且它们可以正常工作，只是nextcloud授权不起作用。

我检查了旧版.jar的内容，并看到类NTLMScheme位于该.jar中，但似乎位于不同的路径。知道如何解决这个问题吗？
