How To Use Javax.xml.transform.stax In Android Studio?

I'm running into a strange problem in Android Studio. I'm also using latest JDK. I can't seem to import the following : javax.xml.stream javax.xml.transform.stax They both are un

Solution 1:

Android doesn't use the same Java JDK as what you use for a desktop or server app; it uses its own implementation of the JDK, which adds the android.* hierarchy but leaves out some packages that are in the standard JDK, especially in the javax.* Java extensions. Unfortunately for you, javax.xml.stream and javax.xml.transform.stax are among the things they didn't choose to implement. Moreover, the Android runtime won't allow you to load any java.* or javax.* classes from an external JAR file for security reasons**. This answer may describe the situation a little better.

Your best bets are probably: 1) use a different third-party library specifically built for Android, such as SimpleXML; 2) look for a repackaged version of the libraries, like this JAXB effort; or 3) use a tool like Jar Jar Links to do the repackaging for you.

** Note: I can't find any documentation from Google to substantiate this; it's just a commonly repeated "fact". If anyone can point to an authoritative statement about Android's handling of third-party java[x].* classes, please comment with a link, or edit this answer.
