Problems with stax-api dependency on Android

(note: offshoot of #116)

Although JDK 1.6 does include Stax API (javax.xml.stream), Google has chosen to create an arbitrary subset of the same and is not included this API. Earlier it even blocked attempts at including any non-included dependencies in javax. namespace, but apparently this has been resolved, at least as far as Stax API is included (by whitelisting?).

But. Since dependency is needed on Android, there is need to either add an otherwise unnecessary dependency (unnecesasry for J2SE/J2EE), which may add unnecessary jar in builds on non-Android platforms; or to add instructions to help Android developers add the dependency explicitly.

I will first add a note on README, for approach two.

@roberttaylor426 FWIW, I managed to get this working on Android by just listing stax as a separate dependency (it looks like javax.* aren’t blocked anymore).

implementation 'javax.xml.stream:stax-api:1.0-2'

I also had to add this to my proguard:

-dontwarn com.fasterxml.**
-keep class com.ctc.wstx.** { *; }
-dontwarn com.ctc.wstx.**

This might be helpful to other Android people.

@cternes I don’t know: I don’t develop on Android. Please ask on mailing lists.
