private Task<Void> createFileIntentSender(DriveContents driveContents) {

    final String inFileName = activity.getDatabasePath(DATABASE_NAME).toString();

    try {
        File dbFile = new File(inFileName);
        FileInputStream fis = new FileInputStream(dbFile);
        OutputStream outputStream = driveContents.getOutputStream();

        // Transfer bytes from the inputfile to the outputfile
        byte[] buffer = new byte[1024];
        int length;
        while ((length = fis.read(buffer)) > 0) {
            outputStream.write(buffer, 0, length);
        }
    } catch (IOException e) {
        e.printStackTrace();

    MetadataChangeSet metadataChangeSet = new MetadataChangeSet.Builder()

    CreateFileActivityOptions createFileActivityOptions =
            new CreateFileActivityOptions.Builder()

                    .setInitialDriveContents(driveContents)
                    .build();

    return mDriveClient
            .newCreateFileActivityIntentSender(createFileActivityOptions)
            .continueWith(

一种可溶的或可替代的产品：

final Task<DriveFolder> rootFolderTask = mDriveResourceClient.getRootFolder();
        final Task<DriveContents> createContentsTask = mDriveResourceClient.createContents();
        Tasks.whenAll(rootFolderTask, createContentsTask)
                .continueWithTask(task -> {
                    DriveFolder parent = rootFolderTask.getResult();
                    DriveContents contents = createContentsTask.getResult();

                    try {
                        File dbFile = new File(inFileName);
                        FileInputStream fis = new FileInputStream(dbFile);
                        OutputStream outputStream = contents.getOutputStream();

                        // Transfer bytes from the inputfile to the outputfile
                        byte[] buffer = new byte[1024];
                        int length;
                        while ((length = fis.read(buffer)) > 0) {
                            outputStream.write(buffer, 0, length);
                        }
                    } catch (IOException e) {
                        e.printStackTrace();
                    }

                    MetadataChangeSet changeSet = new MetadataChangeSet.Builder()
                            .setTitle("appchamada_bkp.db")
                            .setMimeType("application/db")
                            .setStarred(true)
                            .build();

                    return mDriveResourceClient.createFile(parent, changeSet, contents);
                })
                .addOnSuccessListener(activity, new OnSuccessListener<DriveFile>() {
                    @Override
                    public void onSuccess(DriveFile driveFile) {
                        Toast.makeText(activity, "Backup realizado", Toast.LENGTH_SHORT).show();
                    }
                })
                .addOnFailureListener(activity, new OnFailureListener() {
                    @Override
                    public void onFailure(@NonNull Exception e) {
                        Toast.makeText(activity, "Erro ao fazer backup", Toast.LENGTH_SHORT).show();
                    }
                });
        return null;
