Is symbian s60 3rd FP2 edition is backward compatible with s30 2nd edition FP3?
I have developed application in symbian s60 3rd fp2
, I want to tun it in nokia N72
that requires symbian s60 2nd edition fp3
, so do I requi开发者_如何学Gored to make different builds or its backward compatible to 2nd edition fp3
?
Thank you.
It is not backwards compatible. S60 3rd edition is based on Symbian 9, and S60 2nd edition fp3 is based on Symbian 8. Symbian 8 and 9 are binary incompatible. The good news is that the platform security concept was not yet introduced on S60 2nd edition so the porting work should be fairly easy.
the S60 3rd FP2
is based on the Symbian OS v9.3
, while the S60 2nd FP3
is based on the Symbian OS 8.0a
or 8.1
if I remember and it is really, really old version. The source code will be more or less compatible, but you will need to make certain changes especially to prepare the sis file, since e.g. application resource, icon format and the application binary format (exe vs. app) changed...
I suggest you to not try to support those old phones... I am not even sure if the SDK is still available for the download and you might not be allowed to go to the Ovi store with that. but I am not sure here - check it on your own.
