无法将图像上传到azure blob存储android

Question

I m trying to upload an image to azure blob storage. I am using java SDK for azure.I have referenced the libraries. Here is my code..

public void uploadImage(View view) {
    // Do something in response to button click
    try
     {
     String storageConnectionString = 
                RoleEnvironment.getConfigurationSettings().get("StorageConnectionString");
        CloudStorageAccount storageAccount =
                CloudStorageAccount.parse(storageConnectionString);

            // Create the blob client
            CloudBlobClient blobClient = storageAccount.createCloudBlobClient();

            // Retrieve reference to a previously created container
            CloudBlobContainer container = blobClient.getContainerReference("classifieds");

            // Create or overwrite the "myimage.jpg" blob with contents from a local file
            CloudBlockBlob blob = container.getBlockBlobReference("myimage.png");
             InputStream ims = getAssets().open("myimage.png");

            int len =ims.available();
            blob.upload(ims,(long)ims.available());
     }
     catch(Exception ex)
     {
         System.out.println(ex);
     }
}

You can only use RoleEnvironment class when your code is running as a Cloud Service . Since you're running the code in an Android application, this class is not available to you.

If the connection settings are in a configuration file, you may want to resort to another methods to read from that configuration file.
