title: how to launch multiple fragments from a parent fragment?
body: <p>i have a parent fragment and when i click in a button to open  first fragment then click in button in first fragment to open a second fragment and from second fragment to third fragment and so on ....</p>
  
  <p>i succeeded to do that but the application  becomes very slow after launching multiple fragments </p>
  
  <p>this is the code i used to launch any fragment </p>
  
  <pre><code>      button.setOnClickListener(new View.OnClickListener() {
          @Override
          public void onClick(View view)
          {
  
  
              Fragment newFragment = new newFragment();
              FragmentTransaction transaction =  
               getFragmentManager().beginTransaction();
              transaction.replace(fragmentContainer.getId(), newFragment);
  
               transaction.addToBackStack(null);
              transaction.commit();
  
          }
      });
  </code></pre>
