Hi Sudesh,

While creating the project you will get Persistence and Cache  .jar files in the lib folder on your project,so delete those two jar file and try it again .... It will work.

HI

Its the problem executing with the Odata service . Can you please check if any logs are written in /IWFND/ERROR_LOG  and /IWBEP/ERROR_LOG 

also check the traces in ST11 .

[Virinchy]

Can you share a screenshot of the error in Logcat when passing the username and password ?

Make sure the Odata created in SMP 3 using integration gateway provides you the data when you test the Odata service from a web browser. Read this blog to understand how to test the Odata service created,

What type of application you are developing ? If it is a native android app you can download source code of a sample SMP 3 android project from here,

Provide more information on the steps you followed.

Thanks for you suggestion ,let me try in that way also..
