Android GoogleDrive insert.execute（）引发IOException - 如何获得关于错误的更多信息？

Question

我试图上传一个文件到我的GoogleDrive，但是我得到了一个IOException异常，我找不到原因了？怎么了 ？应该修改什么？ 证书，文件路径，文件名，文件类型（text/csv）是正确的... parent_id folderID很好... 和显然我测试过，如果连接到互联网......但没办法，我总是得到这个IOException线：文件= insert.execute（）（我执行的调试器中运行...）

 private File uploadFile(boolean useDirectUpload) throws IOException { 
     java.io.File fileContent = new java.io.File(mFileUri.getPath()); 

     com.google.api.services.drive.model.File fileMetadata = new File(); 
     fileMetadata.setParents(Arrays.asList(new ParentReference().setId(mFolderId))); 
     fileMetadata.setTitle(fileContent.getName()); 
     InputStreamContent mediaContent = new InputStreamContent("text/csv", new BufferedInputStream(new FileInputStream(fileContent))); 
     mediaContent.setLength(fileContent.length()); 

     Drive.Files.Insert insert = mService.files().insert(fileMetadata, mediaContent); 
     MediaHttpUploader uploader = insert.getMediaHttpUploader(); 
     uploader.setDirectUploadEnabled(useDirectUpload); 
     uploader.setChunkSize(MediaHttpUploader.MINIMUM_CHUNK_SIZE); 
     uploader.setProgressListener(new FileUploadProgressListener()); 
     File file = insert.execute(); 
     //return insert.execute(); 
     return file; 
    } 

Answer 1

中的parentID 'mFolderID' 为空。（这是给意义消息WO任何ID ..） 我修改我的设计...先前使用2个线程与WeakReference ...一个用于获取folderID（并设置私有静态字符串mFolderId）和另一个用于上传（使用mFolderID）...但使用WeakReference，mFolderId被设置为null for这个新线程

我现在只使用一个线程，以获得folderID并上传在它的文件...
