  • There are a few problems with your code:

    • Updates in the mobile service are typically implemented with the PATCH HTTP method, not PUT (that's the case in the node.js backend; in the .NET backend you can have a PUT method but you need to implement it yourself).
    • You're sending the data as a UrlEncodedFormEntity; that will send the data as a &-separated name-value pair list. You should send the request using JSON (which is supported on the node.js backend), or enable additional formatters for the .NET backend.
    • You need to send the Content-Type header if you're sending a content in your request. Also X-ZUMO-ACCEPT is not used in the mobile service, so it will be ignored (maybe that's where you should send the Content-Type header instead)

    Another alternative is to use the Android SDK for Azure Mobile Services, which will make it easier to call the mobile service.
