Displaying activity with blur effect in Android Tabs
<p>I have a tab bar in my application, with third tab named About. When user clicks on this About tab, I want activity to be displayed with blur effect. More specifically, About activity should be on front, while previous tab should be displayed behind with blur effect. I did the following code in the about.java onCreate Method, but it opens new window and the previous windows are not being displayed. </p>

<pre><code>public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        //This is the code used to add blur effect
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_BLUR_BEHIND,
                WindowManager.LayoutParams.FLAG_BLUR_BEHIND);
        setContentView(R.layout.about);
}
</code></pre>

<p>If I do it without tab bar it works. Any suggestions on what might be going wrong or how to do it in a different way?</p>
