What in the world are you doing? An application that is built against 1.6 will definitely run on 1.5, as long as you are careful about how you use 1.6 APIs and set your minSdkVersion to 3.
Getting link errors is something much deeper -- do you have native code in your app? If so, is it actually linking against libui.so?? Or is there some other private native API you are using? My first guess would definitely be that you are using some native APIs that exist on 1.6 but not 1.5. On Mon, Nov 30, 2009 at 9:07 PM, Brian Rak <[email protected]> wrote: > Hi there.
