Java NFC(JSR 257) [英] Java NFC (JSR 257)
问题描述
我为支持NFC的诺基亚6131开发了一些小型应用程序.该SDK特别适用于该设备，并且实现了 JSR 257 .
I developed some small applications for the Nokia 6131 that supported NFC. The SDK was special for this device, and it implemented the JSR 257.
现在，我看到了具有专有SDK的不同移动平台，每个平台都提出了不同的功能(Android ICS，Meego，iOS).
Now, I see different mobile platforms with proprietary SDKs, each one proposing different features (Android ICS, Meego, iOS).
我想知道哪个平台仍支持JSR 257?另外，我想知道学习JSR 257是否仍然很有趣，或者我可以采取哪种方式? NFC目前正在扩展，很有趣的是，知道哪些是为此技术开发的标准工具.我不想学习一个新的框架，然后看到两年内它已经完全过时并且不受支持.
I would like to know which platform still support JSR 257? Also, I want to know if learning JSR 257 is still interesting or which way I could take? NFC is currently expanding, and it would be interesting to know which are the standard tools to develop for this technology. I do not want to learn a new framework, and then see that in two years is completely obsolete and unsupported.
推荐答案
JSR 257是针对Java ME平台的，因此不能期望它在其他平台上的直接支持.
JSR 257 is targeted at Java ME platform, so one can not expect its direct support on other platforms.
Android和iOS plaftorms与Java ME绝对不同:
Android and iOS plaftorms are definitely different from Java ME:
据我所知， Meego 还是一个不同的平台.
As far as I can tell, Meego is a different platform, either.
我想知道学习JSR 257是否仍然很有趣
I want to know if learning JSR 257 is still interesting
根据我对以上内容的回忆，答案是否定的，除非有人对将其锁定在有限范围内的手机型号(主要来自诺基亚)的想法感到满意.请注意，这里我指的是JSR 257 API，而不是NFC.
Per my recollection answer to above is no, unless one is comfortable with idea to be locked within a limited range of phone models, mostly from Nokia. Please note here I am referring to JSR 257 API, not to NFC in general.
- 在过去的项目中，我被指派审查我的同事进行的JSR 257 API分析.他的结论(当时我全心全意地同意)是JSR 257 API的设计很差，并且使用它编写可移植的NFC应用程序非常困难.
