I am writing an application that needs to access user stored data such as (SMS conversation, call log, email etc.) on the phone. Look like this is quite impossible for JavaMe, which I love for its portability over phones and platform. The app should be able to send out sms, email, post data over http. Do you guys have any guide/suggestion?
I am also thinking about an solution that have a core module (computing, business logic) written in Java while others written in C, C++ to access native handheld data/API. So I can port the core module over phone platforms and just have to rewrite other modules for different mobiles. Is this approach feasible??
