Error while developing SAP Netweaver mobile App

[Former Member]

Hi All,

I am developing Sample NetWeaver Gateway Application Application in android.

I am able to connect directly to Gateway Server and I am getting Data on my Android Device.

When I connect via SUP Server, I get Error While Making Request.

Android Log is:

Hi Anjor,

I am getting the same error.

We are using SUP 2.2 and Netweaver gateway services.

Can you please share the code how you solved this problem.

Hello,

In the Android code, you need to do following changes:

1. Got to raw -> .Properties file

2. Change the value of Vault password (You can give blank as well )

3. Get the Value of Vault Password:

// the vault password

                    String vaultPassword = this.properties.getProperty("vaultPassword");

4. Use the following code for Registration

supHelper.registerOrUnlock(userName, password, vaultPassword, securityConfig);

Hi All,

I solved the issue by using Data Vault at the time of Authentication.

I note you have a "mobilink" error in your domain logs, does this mean that this is a Replication based Andoid program connecting to SUP then NWG. ?

Or is it a HWC (Hybrid web container) app ?, or a SUP proxy app ?

And what version fo SUP is it 2.1.3 or 2.2 ?.

Hi,

Thanks for reply.

This is Replication based Android Sample Project in which we are using  SUP just as Proxy and trying to connect to Gateway Server.

We are able to register device in SUP and Entry is coming online also.

SUP version is 2.1.3

Please suggest any document for connecting to gateway server via SUP

or

Sample Project ...
