  In the first part Steps to create custom Gateway service and Android application through Eclipse Part 1 , i discussed first three topics:

1. Create a custom RFC Function Module to get PO header and item details. ( Developed in Backend system)

2. Create service in gateway system using above RFC Function Module.

3. Test our service in 'Service Explorer'.

    Create New Project in Eclipse.

http://<hostname>/sap/opu/odata/sap/ZPSR_PO_DATA_SRV_01/

Add Activity for Header details:

Add '+' to add new activity for Item details:

Add Item fields and use Finish button to complete the Application development.

As there is no input criteria, we will get first 50 PO's based on our RFC function module.

Scroll to get next PO’s

Select a PO to navigate to Items.

We can use this .APK file to test it on Android device.

Right click on your project in Eclipse and goto Properties. Under Resource -> Location, you can get above file(.APK) location.
