Hi Yi, I am looking for the KeycodeLabels.h files in /android/frameworks/base/ libs/ui because that is where it is supposed to be, but I cannot find it. I see the KeyLayoutMap.h file but do not see the KeycodeLabels file. I am looking at online versions of the source code file structure and do not see it there either. What am I missing?
