This topic describes how to use the progress bar to indicate the upload progress.

The following code shows how to call the asyncPutObject method to use the progress bar.

// Construct an upload request.
PutObjectRequest put = new PutObjectRequest("<bucketName>", "<objectName>", "<uploadFilePath>");

// Configure the callback function to display the progress bar.
put.setProgressCallback(new OSSProgressCallback<PutObjectRequest>() {
    public void onProgress(PutObjectRequest request, long currentSize, long totalSize) {
        Log.d("PutObject", "currentSize: " + currentSize + " totalSize: " + totalSize);

// Upload the file asynchronously.
OSSAsyncTask task = oss.asyncPutObject(put, new OSSCompletedCallback<PutObjectRequest, PutObjectResult>() {
    public void onSuccess(PutObjectRequest request, PutObjectResult result) {
        Log.d("PutObject", "UploadSuccess");
        Log.d("ETag", result.getETag());
        Log.d("RequestId", result.getRequestId());

    public void onFailure(PutObjectRequest request, ClientException clientExcepion, ServiceException serviceException) {
        // A request exception occurs.
        if (clientExcepion != null) {
            // A local exception (such as network exception) occurs.
        if (serviceException != null) {
            // A service exception occurs.
            Log.e("ErrorCode", serviceException.getErrorCode());
            Log.e("RequestId", serviceException.getRequestId());
            Log.e("HostId", serviceException.getHostId());
            Log.e("RawMessage", serviceException.getRawMessage());
// task.cancel(); // You can cancel the upload task.
// task.waitUntilFinished(); // Wait until the upload task is complete.
