very first method that will be called is onCreate() method.

for getting data from intent:
1) in your 1st activity:

`Intent i = new Intent("your first activity".this , "your 2nd activity class".class);
i.putExtra("id_variable", "id_value");
startactivity(i);`

2) now coming to your 2nd activity...
-get data from 1st activity
-if you are using AsyncTask class you can get data from 1st intent in onPreExecute method (it will run first)
- than in onPostExecute you can have data from db(using api or anything else)
- than simply call that class in you onCreate() method. :)

Hope that Helps.... :)

Edit:
onCreate will be called for sure... onResume will be called when your app turns into background and returns... onPause will be called when your app is in background....
