android - Dropbox 和 Android - 通过 API 调用获取文件名

Question

有谁知道如何获取元数据列表...我的意思是文件和文件夹存在于我们 Android 中 dropbox 的应用程序文件夹中。我需要获取文件和文件夹名称..现在我又想在 Dropbox 中从 android.i reffered dropbox docs 创建文件夹。但没有找到相同的..提前致谢。

Answer 1

这是我所做的，对我来说效果很好。

SavedProperties.selectedAddress 是我的 static 变量，它包含要创建的文件夹的名称。

我在这里

1) 检查文件夹是否存在

2) 如果不存在则创建文件夹。

3) 将文件上传到该文件夹​​。

    private void loadMetadata() 
    {


        // Metadata
        try 
        {
            Entry existingEntry = mApi.metadata("/" + SavedProperties.selectedAddress , 1, null, false, null);
            if(existingEntry.isDir)
            {
                Log.d(TAG, "Folder exists : " + existingEntry.fileName());
                uploadPictures("/"+SavedProperties.selectedAddress + "/");
            }
        } 
        catch (DropboxException  e) 
        {
            Log.d(TAG,"Folder does not exist..." + e.fillInStackTrace());
            try 
            {
                Entry createFolder = mApi.createFolder("/"+SavedProperties.selectedAddress);
                Log.d(TAG,"Folder created..." + createFolder.rev);
                uploadPictures("/"+SavedProperties.selectedAddress + "/");
            } 
            catch (DropboxException e1)
            {
                 Log.d(TAG,"Create Folder DropboxException : " + e1.fillInStackTrace() );
            }       
        }
    }

    private void uploadPictures(String uploadTo) 
    {
        // Uploading Pictures....
        FileInputStream inputStream = null;
        try 
        {
            for(int i =0 ; i < selectedImages.length; i++)
            {
                if(selectedImages[i]==0)
                {
                    String path = PictureGallery.images.get(i).toString().replace("file://", "");
                    String filename = PictureGallery.images.get(i).toString().split("/")[PictureGallery.images.get(i).toString().split("/").length-1];
                    File file = new File(path);
                    inputStream = new FileInputStream(file);
                    Entry newEntry = mApi.putFile(uploadTo + filename, inputStream, file.length(), null, null);
                    Log.i(TAG, "The uploaded file's rev is: " + newEntry.rev);
                    //Log.d(TAG,"PictureGallery " + PictureGallery.images.get(i).toString().split("/")[PictureGallery.images.get(i).toString().split("/").length-1]);
                }
            }
            progress.dismiss();
        } catch (DropboxUnlinkedException e) {
            // User has unlinked, ask them to link again here.
            Log.e(TAG, "User has unlinked.");
        } catch (DropboxException e) {
            Log.e(TAG, "Something went wrong while uploading.");
        } catch (FileNotFoundException e) {
            Log.e(TAG, "File not found.");
        } 
        finally {
            if (inputStream != null) {
                try {
                    inputStream.close();
                } catch (IOException e) {}
            }
        }
    }

在我的案例中我使用了 android sdk 1.3.1。
