J2ME Learning--from WTK to Vendor SDK

For J2ME enthusiasts, basically we all start from Sun WTK (J2ME Wireless Toolkit), but for practical applications, just use WTK is not enough, so in the learning process, must complete from the WTK to the SDK leap.



1, the Manufacturer SDK download address?

2, the manufacturer SDK and WTK What is the difference?



The simplest understanding of the Vendor SDK is to add its own emulator and its own extension API on a WTK basis.



That is, when you use the vendor's SDK, you can use the vendor's extended class library, such as Nokia's UI class library, and the manufacturer's own simulator.



There are not many extension APIs for each vendor, and they are different.



3, how to use?



Some vendor SDK uses are the same as WTK, such as Samsung.



Nokia provides a separate interface for development, but this interface is not used in actual development.



4, the Manufacturer SDK problem



During the Vendor SDK implementation, there are some bugs that are inconsistent with the true machine implementations. For example, Nokia's mix playback problem and so on.







Write for the time being so much, hope to be helpful to everybody's study.
