KD6.QMZ.ULH.LGH.SOC.8IV.MA7.GOU - activation code

I am a native android dev from india . I started outsystems few days ago . I am stuck with a few points .

Help me with few topics - 

1. login page creation connecting to oracle db .

2. Gridview

3. Custom listview

4. Adding logics like refresh page

5. ER diagram components 

Since I am familiar with native code I find this approach a bit complex . Can you provide me a direction to learn or if you have any materials for a native android dev who knows less of HTML , CSS , JAVASCRIPT, your help will be appreciated . Incase you have please contact me on - sambit.dash@bcits.in

Thanks !
