我可以通过以下代码上传图片，但这是 Google Drive 文件上传器.我一次只能上传一个文件.

I can upload image through below code but this is Google Drive file up loader. I can only upload one only one file at a time.

mFile = new java.io.File(fileList.get(i));
                Log.i(TAG, "Creating new contents.");
                Drive.DriveApi.newContents(mGoogleApiClient).addResultCallback(
                        new OnNewContentsCallback() {

                            @Override
                            public void onNewContents(ContentsResult result) {

                                if (!result.getStatus().isSuccess()) {
                                    Log.i(TAG, "Failed to create new contents.");
                                    return;
                                }

                                Log.i(TAG, "New contents created.");

                                OutputStream outputStream = result
                                        .getContents().getOutputStream();

                                byte[] byteStream = new byte[(int) mFile
                                        .length()];
                                try {
                                    outputStream.write(byteStream);
                                } catch (IOException e1) {
                                    Log.i(TAG, "Unable to write file contents.");
                                }

                                MetadataChangeSet metadataChangeSet = new MetadataChangeSet.Builder()
                                        .setMimeType("image/jpeg")
                                        .setMimeType("text/html")
                                        .setTitle("Android Photo.png").build();
                                // Create an intent for the file chooser, and
                                // start it.
                                IntentSender intentSender = Drive.DriveApi
                                        .newCreateFileActivityBuilder()
                                        .setInitialMetadata(metadataChangeSet)
                                        .setInitialContents(
                                                result.getContents())
                                        .build(mGoogleApiClient);
                                try {
                                    mActivity.startIntentSenderForResult(
                                            intentSender, REQUEST_CODE_CREATOR,
                                            null, 0, 0, 0);
                                    publishProgress(1);
                                } catch (SendIntentException e) {
                                    Log.i(TAG, "Failed to launch file chooser.");
                                    publishProgress(0);
                                }
                            }
                        });

但仍在为下载文件而战.

But still fighting for downloading a file.

推荐答案

我得到了解决方案.我们绝不应该使用 Android API 来获得完整的云端硬盘访问权限.我们应该使用纯 java 代码，因为 Google 也说过要访问 Drive 以进行广泛访问，请使用 java 库.

I got the solution. We should never use Android API for complete Drive access. We should work on pure java code as Google also said that to access Drive for broad access use java libraries.

我删除了所有与 Google Play 服务相关的代码.我现在完全使用java，可以轻松上传、删除、编辑、下载所有我想要的东西.

I remove all the code related to Google play services. I am now using completely using java and easily upload, delete, edit, download all whatever I want.

还有一点，Google 文档没有提供关于 Google Drive 与 android api 相关的详细描述，而在使用 java 库时，您可以获得已经创建的方法等等.

One more thing Google doc doesn't provide a detail description about Google Drive in respective to android api while when work on java libraries you can get already created methods and more.

我没有提供任何代码，只是说我或其他对 Drive 完全访问感兴趣的人使用基于 Java 的代码.

I am not giving any code but saying that for me or for others who interested in Drive complete access use Java based codes.
