Answer 1

Query query = new Query.Builder()
    .addFilter(Filters.eq(SearchableField.TITLE, "HelloWorld.java"))
    .build();

Drive.DriveApi.query(googleApiClient, query)
        .setResultCallback(new OnChildrenRetrievedCallback() {

    @Override
    public void onChildrenRetrieved(MetadataBufferResult result) {
        // Iterate over the matching Metadata instances in mdResultSet
    }
});
