Can I upload a stream to Azure blob storage without specifying its length upfront?

Question

I don\'t know if it\'s relevant, but I am using Java with the azure-storage-android-0.2.0.aar for the upload.

I can upload files to Microsoft Azure blob storage

We’ll log feature request to enable uploading from a stream without specifying length. For now, you may want to use the openOutputStream method which has a write method taking a byte[] or an int. An example using the int method is below:

    CloudBlockBlob blockBlob = container.getBlockBlobReference(‘myblob’); // assuming container was already created

    BlobOutputStream blobOutputStream = blockBlob.openOutputStream();
    ByteArrayInputStream inputStream = new ByteArrayInputStream(buffer); // assuming buffer is a byte[] with your data

    int next = inputStream.read();
    while (next != -1) {
          blobOutputStream.write(next);
          next = inputStream.read();
    }

    blobOutputStream.close();
