Unable to show tiles with osmdroid from CloudMade

Question

I'm trying to make work osmdroid with CloudMade (or whatever) but I'm unable to show any tile only blank squares. The only thing I can see in Log cat is

Could not find method org.osmdroid.views.MapView.getScaleX, referenced from method org.osmdroid.views.overlay.SafeDrawOverlay.draw

unable to resolve virtual method 5572: Lorg/osmdroid/views/MapView;.getScaleX ()

I suspect your target SDK is too low. Osmdroid supports SDK 7, but if your device is higher then it will use api calls from the newer API. Target the latest SDK but keep your min SDK at 7.
