There's also a great article on the developer blog about using newer API with an old target: http://android-developers.blogspot.com/2009/04/backward-compatibility-for-android.html
I'm extensively using 1.5 features in my app while still maintaing compatibility with 1.1. The key is to set the target to 2 and wrap every single 1.5 API call through reflection in a wrapper class (see the blog). Using 1.5 XML tags, like Dianne said, is no problem at all and will be ignored on 1.1. Be sure to test on 1.1!! Your app can break in many ways because of something you thought would be fine on 1.1 but isn't. -Mike On Oct 7, 10:33 am, Dianne Hackborn <[email protected]> wrote: > If you set it to 3 it won't be installed on older devices.
