Search folder in google drive by its name and list its content in android

Question

What I want to do I have created the folder through pragmatically in android and done it successfully. Now I want to show the content/ list the files and folders in it(I know in starting it will be empty)

I am searching the folder by its name because the drive id is local id that is not unique through its life time. We get resource Id only when the folder is upload on the server.

Code:

public class ListFilesDrive extends GoogleDrive {

    private static DriveId folderId;
    private ListView mResultsListView;
    private ResultsAdapter mResultsAdapter;
    protected static String bcPlusfolderId;
    private static int ListFileFolder=1;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_listfiles);

        Bundle bundle=getIntent().getExtras();
        bcPlusfolderId=bundle.getString("Folder Id");

        System.out.println("Folder is "+bcPlusfolderId);


        mResultsListView = (ListView) findViewById(R.id.listViewResults);
        mResultsAdapter = new ResultsAdapter(this);
        mResultsListView.setAdapter(mResultsAdapter);
    }

    @Override
    public void onConnected(Bundle connectionHint) {
        super.onConnected(connectionHint);

        if (ListFileFolder==1){
            ListFileFolder++;

            Query query = new Query.Builder().addFilter(Filters.and(
                    Filters.eq(SearchableField.TITLE, "folder_name"),
                    Filters.eq(SearchableField.TRASHED, false))).build();

            Drive.DriveApi.query(getGoogleApiClient(), query)
                    .setResultCallback(metadataCallback);
        }


    }

    final private ResultCallback<DriveApi.MetadataBufferResult> metadataCallback =
            new ResultCallback<DriveApi.MetadataBufferResult>() {
                @Override
                public void onResult(DriveApi.MetadataBufferResult result) {
                    if (!result.getStatus().isSuccess()) {
                        showMessage("Problem while retrieving results");
                        return;
                    }
                    showMessage("Search Done");

                    mResultsAdapter.clear();
                    mResultsAdapter.append(result.getMetadataBuffer());
                }
            };

Result Getting:

I am getting the blank screen and it keeps coming(I think this activity is being calling repeatedly. )
