I builded a game in corona sdk and when I want to build my game to android after it says:
D:\Corona SDK\Resources\debug.keystore was not valid
What can I do for this?
I have never used Corona SDK, however seems like you are using the wrong user/password for your debug.keystore
file.
The default user/password for the debug.keystore
is android/android, unless you have already changes those values.
