“All SYMBIAN based end devices accept Java language Applications”

(i) Does this mean that the applications made for Android would run in S60 , without any modifications??
(ii) If not then what exactly we mean when we say the above statement?? Is there any web link to which I can refer to??
(iii) What are the coding guidelines that we need to follow so that an Android application can be ported on S60 with minimum changes??

Thank you all in advance.

Android's Java is Google's on variation (not the same as the "regular" J2ME, MIDP/CLDC). Android has a Google "proprietary" Java VM and libraries.

So, Android Java apps will not run on phones that support J2ME and vice versa is presumably true as well.

I haven't read/seen any porting guides/instructions (not that I have searched for them, either).

He's right... Google have, for some reason, chosen to make their "Java" completely incompatible with all standards, so that there is no application compatibility in either direction.

On the other hand, Symbian and Windows Mobile (for example) can run the same Java applications, because the MIDP standard is supported on both.

"Without modification" is a big statement. In practice, modification is often required. For example, if I write a Java application that relies on a touch screen, then it will need modifying to be usable on a non-touch screen device. Other device differences can also require code modifications, even between devices that support the same standard.

Hi,

I am looking forward to coming with some coding guidelines so that an android application can be ported on S60 with minimum modifications. Like excluding the UI (which definitely has to be rebuilt for S60), what should a developer keep in mind so that his/her code is platform (android/S60) independant.

Can you help me with this??

Thanks in advance.
