Hai 正在关注 Google Drive Api 演示。这里无法在公用文件夹中创建文件

package com.google.android.gms.drive.sample.demo;
import android.os.Bundle;

import com.google.android.gms.common.api.ResultCallback;
import com.google.android.gms.drive.Drive;
import com.google.android.gms.drive.DriveApi.ContentsResult;
import com.google.android.gms.drive.DriveApi.DriveIdResult;
import com.google.android.gms.drive.DriveFolder;
import com.google.android.gms.drive.DriveFolder.DriveFileResult;
import com.google.android.gms.drive.DriveId;
import com.google.android.gms.drive.MetadataChangeSet;

import java.lang.Override;


/**
 * An activity to create a file inside a folder.
*/
public class CreateFileInFolderActivity extends BaseDemoActivity {

private DriveId mFolderDriveId;

@Override
public void onConnected(Bundle connectionHint) {
    super.onConnected(connectionHint);
    Drive.DriveApi.fetchDriveId(getGoogleApiClient(), EXISTING_FOLDER_ID)
            .setResultCallback(idCallback);
}

final private ResultCallback<DriveIdResult> idCallback = new ResultCallback<DriveIdResult>() {
    @Override
    public void onResult(DriveIdResult result) {
        if (!result.getStatus().isSuccess()) {
            showMessage("Cannot find DriveId. Are you authorized to view this file?");
            return;
        }
        mFolderDriveId = result.getDriveId();
        Drive.DriveApi.newContents(getGoogleApiClient())
                .setResultCallback(contentsResult);
    }
};

final private ResultCallback<ContentsResult> contentsResult = new
        ResultCallback<ContentsResult>() {
    @Override
    public void onResult(ContentsResult result) {
        if (!result.getStatus().isSuccess()) {
            showMessage("Error while trying to create new file contents");
            return;
        }
        DriveFolder folder = Drive.DriveApi.getFolder(getGoogleApiClient(), mFolderDriveId);
        MetadataChangeSet changeSet = new MetadataChangeSet.Builder()
                .setTitle("Sujatha.txt")
                .setMimeType("text/plain")
                .setStarred(true).build();
        folder.createFile(getGoogleApiClient(), changeSet, result.getContents())
                .setResultCallback(fileCallback);
    }
};

final private ResultCallback<DriveFileResult> fileCallback = new
        ResultCallback<DriveFileResult>() {
    @Override
    public void onResult(DriveFileResult result) {
        if (!result.getStatus().isSuccess()) {
            showMessage("Error while trying to create the file");
            return;
        }
        showMessage("Created a file: " + result.getDriveFile().getDriveId());
    }
};

}

我的公用文件夹是这个 ，也是
EXISTING_FOLDER_ID = "0B2uTE9KZI1PTRXEwQ00xRkt0Wk0"

仍然无法在此文件夹中创建文本文件。它显示了这条消息Cannot find DriveId. Are you authorized to view this file?，我将文件夹设为公开，并将其设置为可以在共享选项中进行编辑。

任何建议将不胜感激。

提前致谢

  1. 我能够在我的谷歌驱动器中创建文件和文件夹。但不是我上面提到的特定文件夹。

除非您的应用程序的用户从您的应用程序中选择该文件夹，否则您的应用程序不会被授予对该文件夹的访问权限。在这里阅读更多内容 - https://stackoverflow.com/a/25881227/1363471

从您的终端创建一个文件并将其上传到 GDrive 文件夹

private void saveFileToDrive(final String name) {
        Thread t = new Thread(new Runnable() {
          @Override
          public void run() {
              try
              {
                  FileContent mediaContent = new FileContent("plain/text", yourfilename);
                  com.google.api.services.drive.model.File body = new com.google.api.services.drive.model.File();
                  body.setTitle(name);
                  body.setMimeType("plain/text"); 
                  com.google.api.services.drive.model.File file = servicer.files().insert(body, mediaContent).execute();
                  if (file != null)
                  {
                      runOnUiThread(new Runnable() {
                        @Override
                        public void run() {
                        Toast toast = Toast.makeText(getApplicationContext(), "File exported successfully", 2000).toast.show();
                        }
                      }
                      );

                  }

              }
              catch (UserRecoverableAuthIOException e)
              {
                  startActivityForResult(e.getIntent(), REQUEST_AUTHORIZATION);
              }
              catch (IOException e)
              {
                  e.printStackTrace();
              }
          }
      });
      t.start();
    }
