title: android: how do I use tabhost/tabwidget (genrally tabs) putting different activities on tabcontents
body: <p>Firstly!,
  I've used the generated <code>Activity</code> using the tab navigation type. I just used it to automatically generate <code>Tab</code> control on the <code>Activity</code>. Its on the latest <em>ADT</em>.I think :(,, 
  Now my question is how do I use the <code>Fragments</code> from other <code>Activity</code> in to the <code>Tab</code> contents</p>
  
  <p>secondly,
  Is there any other way to put another <code>Activity</code> inside the <code>Tab</code> content which on the, lets say its MainACtivity.class?....</p>
  
  <p>Planning to have 3 <code>Tab</code>s with 3 different <code>Activity</code>s, each of which contains 1 <code>Activity</code> per <code>tab</code> content</p>
  
  <p>Really need ur help guys I have run out of ideas and sources :( :( ...
  Kind of new to android development so be gentle. :) </p>
