+         theme is applied to your application by default. As such, your app might appear with the
+         {@link #Theme_Holo Holo} styles on one device, but with a different set of styles on
+         another device. This is great if you want your app to fit with the device's native look and
+         feel. If, however, you prefer to keep your UI style the same across all devices, you should
+         apply a specific theme such as {@link #Theme_Holo Holo} or one of your own design. For more
