How to determine the status bar extension?

My application allows me to run another application with me. None of my actions show a status bar. But when you start other applications, such as Camera, the user can access status bar. So I tried the following code snippet to collapse status barinside the service (so it collapses every time, and the code always works).

int currentapiVersion = android.os.Build.VERSION.SDK_INT;
Object service = getSystemService("statusbar");
Class<?> statusbarManager = Class.forName("android.app.StatusBarManager");
Method collapse = null;
if(currentapiVersion <= 16){
    collapse = statusbarManager.getMethod("collapse");
}else{
    collapse = statusbarManager.getMethod("collapsePanels");
}
collapse.setAccessible(true);
collapse.invoke(service);

Now I want to collapse status baronly if the user tries to expand this.Is exist intentor intent filterto detect the extension status bar?

Thanks at Advance

There is no callback if the notification bar is dragged onto Android.

onWindowFocusChanged() .

<uses-permission android:name="android.permission.EXPAND_STATUS_BAR" />


@Override
public void onWindowFocusChanged(boolean hasFocus)
{
    try
    {
        if(!hasFocus)
        {
            Object service  = getSystemService("statusbar");
            Class<?> statusbarManager = Class.forName("android.app.StatusBarManager");
            Method collapse = statusbarManager.getMethod("collapse");
            collapse .setAccessible(true);
            collapse .invoke(service);
        }
    }
    catch(Exception ex)
    {
        if(!hasFocus)
        {
            try {
                Object service  = getSystemService("statusbar");
                Class<?> statusbarManager = Class.forName("android.app.StatusBarManager");
                Method collapse = statusbarManager.getMethod("collapse");
                collapse .setAccessible(true);
                collapse .invoke(service);

            } catch (Exception e) {
                // TODO Auto-generated catch block
                e.printStackTrace();                
            }
            ex.printStackTrace();
        }
    }
}
