Не удается получить список файлов из Dropbox в android

Question

Я не могу получить список файлов из Dropbox.

package com.example.contactmaster.dropbox_api; 

    import java.util.ArrayList; 
    import android.os.AsyncTask; 

    import com.dropbox.client2.DropboxAPI; 
    import com.dropbox.client2.DropboxAPI.Entry; 
    import com.dropbox.client2.android.AndroidAuthSession; 
    import com.dropbox.client2.exception.DropboxException; 

    public class ListFiles extends AsyncTask<Void, Void, Boolean> { 
     private DropboxAPI<AndroidAuthSession> dropboxApi; 
     private String path; 

     public ListFiles(DropboxAPI<AndroidAuthSession> dropbox, String fILE_DIR) { 
      // TODO Auto-generated constructor stub 
      dropboxApi = dropbox; 
      path = fILE_DIR; 
     } 

     @Override 
     protected Boolean doInBackground(Void... params) { 
      System.out.println("=== List File "); 
      ArrayList<String> files = new ArrayList<String>(); 
      try { 
       Entry directory = dropboxApi.metadata(path, 1000, null, true, null); 
       for (Entry entry : directory.contents) { 
        if (!entry.isDir) 
         files.add(entry.fileName()); 
        else 
         files.add("___" + entry.fileName()); 
       } 

       System.out.println("=== Array List : " + files.size()); 
      } catch (DropboxException e) { 
       e.printStackTrace(); 
      } 

      return true; 
     } 

    } 

Я создал этот AsyncTask и вызвать из MainActivity как.

Answer 1

if (key != null && secret != null) { 
    AccessTokenPair token = new AccessTokenPair(key, secret); 
    session = new AndroidAuthSession(appKeyPair, ACCESS_TYPE, token); 
} else { 
    session = new AndroidAuthSession(appKeyPair, ACCESS_TYPE); 
} 

dropboxApi = new DropboxAPI<AndroidAuthSession>(session);
