Question

Android の Sardine に大きな問題があります。Android 用の Sardine ライブラリをダウンロードして、プロジェクトで使用しています。PUT と GET メソッドは機能しますが、LIST メソッドは機能せず、理由がわかりません。

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
    StrictMode.setThreadPolicy(policy);
    try {
        Sardine sardine = SardineFactory.begin("username", "password");
        List<DavResource> resources = sardine.list("https://myserver.com/");

        for (DavResource res : resources)
        {
            Log.i("Resources", res.getName());
        }

    } catch (ExceptionInInitializerError e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } catch (NullPointerException e) {
        e.printStackTrace();
    }

}

これは私のプログラムの LogCat コンソールです:

必要なヘルプ。

どうもありがとう！

同様のエラーが発生し、一部の要素に Prop.java クラス "(required = false)" を追加する必要がありました。

例：

@Element (required = false)
private Resourcetype resourcetype;
@Element (required = false)
private String creationdate;
@Element (required = false)
private String getlastmodified;
@Element (required = false)
private String getetag;
@Element (required = false)
private String getcontenttype;

あなたの場合、Response.java と Propstat.java の両方で propstat が定義されているようです。たぶん、それらの1つの名前を単に「prop」に変更してください。
