URL and sasQueryToken not generating

[shashi2459]

I am following this doc https://azure.microsoft.com/en-in/documentation/articles/mobile-services-android-upload-data-blob-storage/ for uploading blob to azure cloud using Mobile Service. But url and sas token is not getting generated. any suggestions?

[emgerner-msft]

Please give the actual code you're using and what's going wrong. For example, is it throwing an error, or are you getting back a different token than you expect?

Basically, please answer: What did you do? What did you expect to happen? What actually happened?

[shashi2459]

I am using the same upload() function from doc, except changed the class I am interested in. I want to upload the image in blob on azure cloud and I am using Azure Mobile Service for this. And as per the doc, I have configured my account on portal and I should get an object containing Generated URL and SASQueryString, but I am getting null values for URL and SAS string. Due to this, I am not able to proceed further and getting exception of Address should be absolute address since the SAS string is empty.

[emgerner-msft]

Please give the exact code you use. As you mentioned, you're not following it exactly -- you've changed the class and I'm not sure what that means. I need exactly the code you used that isn't working if I'm going to help debug since we know the sample works as is (we've run it).

I mean I have changed the class name and added few fields and kept all the fields mentioned in the ToDoItem class. The insertion is working on EASY TABLE I have created on Azure cloud.

Thanks! How are you actually populating the class? Calling getImageUri and getSasQueryString just return whatever is set on the item. The code which actually generates shared access signatures is much earlier in the sample.

[shashi2459]

Class population is in uploadPhoto(). So empty values are assigned to uri and SAS string. Same is done in the sample.

[emgerner-msft]

I think there's a bit of a misunderstanding on how the sample works, not really the library. Can you please post something like that question on the sample itself? The author will better be able to help you.

[shashi2459]

ok...Thanks by the way.
