Application crash when I try to open text file

[dfistric]

Hi,

I imported this sample to Android studio, but I have one small problem and don't know whats causing it.
Everything works except opening text file inside editor.

I traced the problem to:

    private void get() {
        Log.d(TAG, "Retrieving...");
        DriveFile file = Drive.DriveApi.getFile(mGoogleApiClient, mCurrentDriveId);
        final PendingResult<MetadataResult>
                metadataResult = file.getMetadata(mGoogleApiClient);
        final PendingResult<DriveContentsResult>
                contentsResult = file.open(mGoogleApiClient,
                DriveFile.MODE_READ_ONLY | DriveFile.MODE_WRITE_ONLY, null);
    }

to be exact this line:

            DriveFile file = Drive.DriveApi.getFile(mGoogleApiClient, mCurrentDriveId);

it produced following error:

Client must be connected. Don't understand because mGoogleApiClient and mCurrentDriveId have their values and connection to the drive works because I can create files, can get list of files and so on.

I also tried few different samples like Android quickstart and it also fails on ReadContents.

Don't know what I'm missing here. On developer console I added credentials to accept this application (w/o it can't connect), Google Drive API is enabled, is there maybe something else.

Sorry if I'm missing something obvious.

DriveFile driveFile=mSelectedFileDriveId.asDriveFile();
I used this method to solve problem
