java.lang.NoSuchMethodError: No static method newFactory() Ljavax/xml/stream/XMLInputFactory

[samimejri]

I am working on an android app using semantic kernel and I have this issue that I have been battling for 2 days now. In the semantic kernel code, the use of the newFactory() static method for prompt parsing is the root cause. I think this is not needed and newInstance() can do the job.

This github issue is talking about the problem I am facing but in another library: FasterXML/jackson-dataformat-xml#533

I have this issue when I use invokePromptAsync() but not when I use getChatMessageContentsAsync().

The problem is easy to reproduce, create a new project in android studio and use any sample that has a call to invokePromptAsync()

@samimejri Can you send in the snippet of code you're executing?

Thanks for responding.
Here is a repo that I made to share this issue: https://github.com/samimejri/SKTest

The problem occurs at runtime. When launching the app you will get this error:

@samimejri have you tried adding the stax-api dependency to your project:

<dependency>
  <groupId>javax.xml.stream</groupId>
  <artifactId>stax-api</artifactId>
  <version>1.0-2</version>
</dependency>

https://github.com/samimejri/SKTest/blob/master/app/build.gradle.kts

stax-api is already added in the dependencies. It DOES NOT RESOLVE the issue. The implementation of stax-api does not have the static newFactory() method.

Like I said, using the newInstance() method instead newFactory() here will resolve the issue for Android.

@samimejri yeah I agree moving it to newInstance should fix it

Sorry for the delay! I created the pull request.

It's my first open source project contribution and the first java code I touched in years... Please bear with me!
