我正在开发的 Android 应用程序与 Google Drive 集成。我有一个在驱动器上复制文件的功能,我使用以下代码:
File newFile = new File();
newFile.setTitle(mItem.GetName());
ParentReference newParent = new ParentReference();
newParent.setId(gDriveFolder.getFileId());
List<ParentReference> parents = new ArrayList<ParentReference>(1);
parents.add(newParent);
newFile.setParents(parents);
File copiedFile = service.files().copy(mItem.getFileId(), newFile).execute();
String copiedFileId = copiedFile.getId();
long copiedModDate = copiedFile.getModifiedDate().getValue();
Log.d("serverSideCopyMove", "File returned from copy command has modified date of " + copiedModDate);
// bug here in google drive because the last mod date returned from the above
// gets changed a few micro-seconds later, thus the need to make a separate
// server call to get new mod date again
File getFile = service.files().get(copiedFileId).execute();
copiedModDate = getFile.getModifiedDate().getValue(); //why different value?
Log.d("serverSideCopyMove", "Separate call to get same copied file returns modified date of " + copiedModDate);
// end of workaround
您将从我的代码中看到,从复制命令返回的文件的修改日期与我对同一文件执行“获取”时不同。我只是想知道这是一个错误还是我错误地使用了调用?
