I know in Android 4.4 KitKat (API 19) it\'s possible to make the status bar transparent.

But for example, Go Launcher Ex and others have an option to make it transpa

Use this. :)

after super() and before set content.

if (Build.VERSION.SDK_INT >= 19)
{
    getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
}

if (Build.VERSION.SDK_INT >= 19 && Build.VERSION.SDK_INT < 21)
{
    setWindowFlag(this, WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, true);
}

if (Build.VERSION.SDK_INT >= 21)
{
    setWindowFlag(this, WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, false);
    getWindow().setStatusBarColor(Color.TRANSPARENT);
}


public static void setWindowFlag(Activity activity, final int bits, boolean state)
{
    Window win = activity.getWindow();
    WindowManager.LayoutParams winParams = win.getAttributes();

    if (state)
     {
        winParams.flags |= bits;
    }
     else
     {
        winParams.flags &= ~bits;
    }
}
