It is fine.

These are only declarations for external classes. The tool that 
generates the declarations for the external classes cannot determine 
whether a method is new or inherited from a parent class, so it always 
adds "virtual" instead of "override" in case it's an overriding method. 
That is where the hint comes from. The actual classes are implemented in 
Java/Dalvik and part of the Android class libraries, and are correct.

If you would do the same with a class implemented in Pascal, then the 
compiler would print an error instead of a hint, because then the 
compiled code would not work as expected.
