Android Azure Storage Blob upload with SAS; com.microsoft.azure.storage.StorageException: The specified resource does not exist

Question

I am trying to upload a file to Azure Storage as blob from android using Microsoft Azure Storage SDK for Android and Azure Mobile service.

Actually I wasn't able to find any sample code using the Shared Access Signature (SAS) in android. The above mentioned mobile service tutorial is for .NET application. So following the same tutorial I am trying to create a sample app in android for image upload

Here is my android code:

 AsyncTask<Void, Void, Void> task = new AsyncTask<Void, Void, Void>(){
        @Override
        protected Void doInBackground(Void... params) {
            try {
                final ImageItem entity = addItemInTable(item);
                Log.d("InsertedItem:", entity.toString());

                StorageCredentials cred = StorageCredentials.tryParseCredentials(entity.getSasQueryString());

                URI imageURI = new URI(entity.getImageUri());

                URI containerUri = new URI("https://" + imageURI.getHost() + "/" + entity.getContainerName());
                Log.d("ContainerURI:", containerUri.toString());

                CloudBlobContainer container = new CloudBlobContainer(containerUri, cred);

                CloudBlockBlob blobFromSASCredential = container.getBlockBlobReference(entity.getResourceName());
                AssetManager assManager = getApplicationContext().getAssets();
                InputStream is = null;
                try {
                    is = assManager.open("image.jpg");

                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
                blobFromSASCredential.upload(is, -1);
              //blobFromSASCredential.uploadText("Sample text");


                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        if (!entity.isComplete()) {
                            mAdapter.add(entity);
                        }
                    }
                });
            } catch (final Exception e) {
                e.printStackTrace();
                createAndShowDialogFromTask(e, "Error");
            }
            return null;
        }
    };

public ImageItem addItemInTable(ImageItem item) throws ExecutionException, InterruptedException {
    item.setContainerName("todoitemimages");
    item.setResourceName(UUID.randomUUID().toString());

    ImageItem entity = mToDoTable.insert(item).get();
    return entity;
}

Here is my GSON object:

public class ImageItem {
/**
 * imageUri : sample string 6
 * containerName : sample string 3
 * sasQueryString : sample string 5
 * resourceName : sample string 4
 * text : sample string 1
 * id : sample string 7
 * complete : true
 */
@SerializedName("imageUri")
private String imageUri;
@SerializedName("containerName")
private String containerName;
@SerializedName("sasQueryString")
private String sasQueryString;
@SerializedName("resourceName")
private String resourceName;
@SerializedName("text")
private String text;
@SerializedName("id")
private String id;
@SerializedName("complete")
private boolean complete;
}

While running the code I get this error:

Answer 1

StorageCredentials.tryParseCredentials() takes a connection string, so this isn't quite the right method I think. Try just directly creating the credentials object you want using the StorageCredentialsSharedAccessSignature constructor which takes the SAS token.

Additionally, in order to upload a blob you need to be sure the container you're uploading it to exists. If you're sure it does, then this code is good. Otherwise, the create() or createIfNotExists() methods on the container object are what you'll need.
