推荐答案

不支持！

Android的运行时间是不太JME。 iText的是从来没有移植到JME摆在首位。

Android's runtime isn't quite JME. iText was never ported to JME in the first place.

说了这么多，有一对夫妇iText->的Andr​​oid端口左右浮动。但是，这仅仅是通过谁已经撕去了很大一部分少数知情人士这样做，他们就不必端口一切的一个子集的一子集加一些-其他-的东西，是Android运行。

Having said that, there are a couple iText->Android ports floating around. But this has only been done by a few Knowledgeable Individuals who have ripped out large portions so they wouldn't have to port Everything to a subset-of-a-subset-plus-some-other-stuff that is the Android Runtime.

据我了解，iText的正确（这件事）的某个端口是在作品中，但不知道它是否会永远去任何地方，或者当人们将能够获得它自己的手中。

I understand that a port of iText Proper (the whole thing) is In The Works, but have no idea if it'll ever go anywhere, or when folks will be able to get their hands on it.
