Hi Ali,

First of all thank you so much for this light to unregister a user on SMP. I have 2 questions, when you say "MOST important part!" context.setChannel(LogonCore.Channel.REST); line, why do you say that? Sorry I'm begining with these OData Libraries and I'm not setting this Channel to my context, but my registration it's working fine. What means to set Channel.REST? And the other question, are you working now with Technical Cache?

Thanks in advances.

Best regards,
Ana Velásquez

Hey, Ana.

During my development, there was a time when I could successfully register, but they all showed with the user nosec_identity on the SMP admin cockpit. Debugging showed that the username and password were not being sent.

After a lot of back and forth with SAP, they gave the fix which was to set the channel to LogonCore.Channel.REST. Now the registration on SMP admin cockpit shows with the proper username.

If it works for you without using REST, then you may remove it. Maybe it was our SMP configuration which required this to be set.

For your second question; yes, I'm using the technical cache for OData Online Store.

Ali and do you have a hint on how to implement Technical Cache? I'm developing a native android app using OnlineStore but it may be occasionally offline, for what I've read so far, Technical Cache it's the approach for achieve this. Thank you again. I have other 2 questions, are you working with which versions, SDK and Server? and when you refer to OnlineStore.getInstance().getOnlineStore().close(); that "OnlineStore" is an instance of what, or is the library? I ask this because I'm working with SDK SP05 and the way I open my OnlineStore is this:

OnlineODataStore.open(context, uri, manager, openListener, null);

But I cannot find on what object I should call the .getInstance().getOnlineStore().close(), I don't know If you do understand me.

Thanks in advance again.

To implement technical cache, you need to pass an OnlineODataStore.OnlineStoreOptions object to the open method.

 OnlineODataStore.OnlineStoreOptions options = new OnlineODataStore.OnlineStoreOptions(OnlineODataStore.PayloadFormatEnum.JSON); // I use JSON, you can choose XML if you want

 options.useCache = true;
 options.cacheEncryptionKey = "my_secret_key";

And then;

 OnlineODataStore.open(context, uri, manager, openListener, options);

And the SDK will take care of the rest.

As for the code you cannot find, that's my own class for convenience access to the Online Store. I'll edit the gist to remove it.

Hi Ali,

I was wondering if you could help me with an issue I'm having and I'll like to know how are you handle it, since on internet I could not find any information of this. The problem is to handle the connection errors of the device to the Managment Cockpit.

I would really appretiate any light that you can give me on this.

Thanks in advance.

Best regards,
Ana

Hi Ali, your code are really helpful, thank you very much.
Is it possible for you to share code of DashboardActivity.class as well?
I really want to learn How to get the business data from backend system.
Now I have successfully registered to SMP through my app.
