Android : How to send multiple images those are present in folder to the google drive in android programmatically?

I want to send multiple images those are present in my internal storage and when i selects that folder i want upload that folder into google drive. i have tried this google drive api for android https://developers.google.com/drive/android/create-file and i have used the below code but it shows some error in getGoogleApiClient

the code is

ResultCallback<DriveContentsResult> contentsCallback = new
        ResultCallback<DriveContentsResult>() {
    @Override
    public void onResult(DriveContentsResult result) {
        if (!result.getStatus().isSuccess()) {
            // Handle error
            return;
        }

        MetadataChangeSet metadataChangeSet = new MetadataChangeSet.Builder()
                .setMimeType("text/html").build();
        IntentSender intentSender = Drive.DriveApi
                .newCreateFileActivityBuilder()
                .setInitialMetadata(metadataChangeSet)
                .setInitialDriveContents(result.getDriveContents())
                .build(getGoogleApiClient());
        try {
            startIntentSenderForResult(intentSender, 1, null, 0, 0, 0);
        } catch (SendIntentException e) {
            // Handle the exception
        }
    }
}

is there any approach to send images to drive or gmail?
