Would it not be possible for the compiler to throw up some warning about this? i.e. if there is some resource referred to which is not publicly defined in at least one of the SDK levels not less than that specified in minSdkVersion?

How to debug this? I'm not aware I'm using any "private"/"internal" resources or any public resources introduced after SDK level 4 (which I set the minSdkVersion to) 2. How to safeguard against this? I've tested my app in the emulator at SDK level 4,7,8 & 9. Everything worked fine. I haven't tested it at level 5 or 6 because they don't seem to be available in the AVD Manager but anyway I would think it unlikely that a resource would be defined in levels 4&7 but not 5. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
