apps with no <uses-sdk> get strange values of minSdkVersion

apps with no <uses-sdk> get strange values of minSdkVersion

Using this example app which does not have <uses-sdk>:
https://android.googlesource.com/platform/development/+log/master/samples/ApiDemos/assets/HelloActivity.apk

aapt then returns "sdkVersion:'IceCreamSandwich'".  minSdkVersion is only
ever supposed to be an integer, so this is a bizarre APK.  It is included
only as a binary in the git repo for Android sample code.  But who knows
what else is out there, so report and error and carry on with the update
process.
