Question

final Task<DriveFolder> appFolderTask = getDriveResourceClient().getAppFolder();
final Task<DriveContents> createContentsTask = getDriveResourceClient().createContents();
Tasks.whenAll(appFolderTask, createContentsTask)
        .continueWithTask(new Continuation<Void, Task<DriveFile>>() {
            @Override
            public Task<DriveFile> then(@NonNull Task<Void> task) throws Exception {
                DriveFolder parent = appFolderTask.getResult();
                DriveContents contents = createContentsTask.getResult();
                OutputStream outputStream = contents.getOutputStream();
                try (Writer writer = new OutputStreamWriter(outputStream)) {
                    writer.write(data);
                }

                MetadataChangeSet changeSet = new MetadataChangeSet.Builder()
                        .setTitle("Demo`enter code here`")
                        .setMimeType("text/plain")
                        .setStarred(true)
                        .build();

                return getDriveResourceClient().createFile(parent, changeSet, contents);
            }
        })
        .addOnSuccessListener(this,
                new OnSuccessListener<DriveFile>() {
                    @SuppressLint("StringFormatInvalid")
                    @Override
                    public void onSuccess(DriveFile driveFile) {
                        showMessage(getString(R.string.file_created,
                                driveFile.getDriveId().encodeToString()));
                        //finish();
                    }
                })
        .addOnFailureListener(this, new OnFailureListener() {
            @Override
            public void onFailure(@NonNull Exception e) {
                Log.e(TAG, "Unable to create file", e);
                showMessage(getString(R.string.file_create_error));
                //finish();
            }
        });

我已成功将文件上传到app文件夹，但没有从Drive的应用文件夹中获取任何资源。

怎么可能？

我通过从driveResourceClient实例调用getAppFolder方法获得了我的答案

import json

a = '\ud83d\udc95'
m = json.dumps({"k": a})
print(json.loads(m)["k"])  #
