title: android sidebar navigation without using fragments
body: <p>I want to create an activity that has sidebar on the left that is not changing between activity transitions (like split view in ios). It seems that I can do this with fragments but I need to add support for devices that is prior to HoneyComb. </p>
  
  <p>I tried using a layout something like below. </p>
  
  <pre><code>   &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="fill_parent"
      android:layout_height="fill_parent"
      android:orientation="horizontal" &gt;
  &lt;LinearLayout android:layout_width="320dip"
       android:layout_height="match_parent"
       android:id="@+id/navLay"
      &gt;
   &lt;ListView
           android:id="@+id/navList"
           android:layout_width="match_parent"
           android:layout_height="wrap_content" &gt;
       &lt;/ListView&gt;
  
   &lt;/LinearLayout&gt;
    &lt;LinearLayout 
       android:layout_width="wrap_content"
       android:layout_height="match_parent"
       android:id="@+id/contentLay"
       &gt;&lt;ListView
        android:id="@+id/contentList"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" &gt;
    &lt;/ListView&gt;
   &lt;/LinearLayout&gt;
  &lt;/LinearLayout&gt;
  </code></pre>
  
  <p>But the first list is also updated on activity transition. I want to note that the activity is the same activity except the right list's data source is different. So it would be pretty good if I could save state and content of  the left navigation bar while navigating. Any help will be appreciated.</p>
