Upload File to Google Drive

try {
    final java.io.File uploadFile = new java.io.File(filePath);
    File fileMetadata = new File();
    ParentReference newParent = new ParentReference();
    newParent.setId(upload_folder_ID);
    fileMetadata.setParents(
            Arrays.asList(newParent));
    fileMetadata.setTitle(fileName);
    InputStreamContent mediaContent = new InputStreamContent(MIMEType, new BufferedInputStream(
                new FileInputStream(uploadFile) {
                    @Override
                    public int read(byte[] buffer,
                            int byteOffset, int byteCount)
                            throws IOException {
                        // TODO Auto-generated method stub
                        Log.i("chauster","progress = "+byteCount);
                        return super.read(buffer, byteOffset, byteCount);
                    }
                }));
            mediaContent.setLength(uploadFile.length());
    insert = service.files().insert(fileMetadata, mediaContent);
    MediaHttpUploader uploader = insert.getMediaHttpUploader();
    FileUploadProgressListener listener = new FileUploadProgressListener();
    uploader.setProgressListener(listener);
    uploader.setDirectUploadEnabled(true);
    insert.execute();
} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

public class FileUploadProgressListener implements MediaHttpUploaderProgressListener {

    @SuppressWarnings("incomplete-switch")
    @Override
    public void progressChanged(MediaHttpUploader uploader) throws IOException {
        switch (uploader.getUploadState()) {
            case INITIATION_STARTED:
                break;
            case INITIATION_COMPLETE:
                break;
            case MEDIA_IN_PROGRESS:
                break;
            case MEDIA_COMPLETE:
                break;
