Can Google Drive Android API be used to list all the files on google drive?

Question

I want to list all the file on user's google drive(all files not just created by application) and then download the selected one. I found there are two APIs Google Drive API for android and Google Drive REST API. After searching a lot i know that i can get list of files using REST API but not sure about Android API. Please guide me how to proceed.

Files.list can be used for Android as well. You can see that in this Android Quickstart

/**
 * Fetch a list of up to 10 file names and IDs.
 * @return List of Strings describing files, or an empty list if no files
 *         found.
 * @throws IOException
 */
private List<String> getDataFromApi() throws IOException {
    // Get a list of up to 10 files.
    List<String> fileInfo = new ArrayList<String>();
    FileList result = mService.files().list()
         .setPageSize(10)
         .setFields("nextPageToken, files(id, name)")
         .execute();
    List<File> files = result.getFiles();
    if (files != null) {
        for (File file : files) {
            fileInfo.add(String.format("%s (%s)\n",
                    file.getName(), file.getId()));
        }
    }
    return fileInfo;
}
