NullPointerException （ Interactive-ink-examples-android 1.5 https://github.com/MyScript/interactive-ink-examples-android）

When I tried the 1.5 version of the Demo, I found that there was a null pointer exception and a crash error：

Process: com.myscript.iink.demo, PID: 14799
java.lang.NullPointerException: Attempt to get length of null array
at com.myscript.iink.uireferenceimplementation.SmartGuideView.computeModificationOfWords(SmartGuideView.java:626)
at com.myscript.iink.uireferenceimplementation.SmartGuideView.update(SmartGuideView.java:531)

 In addition, in order to avoid a crash in such a situation, you can add a check on oldWords in the SmartGuideView class:

 

 

 

private void computeModificationOfWords(SmartGuideWord[] words, SmartGuideWord[] oldWords)
if (oldWords == null) return;
...

Thank you for contacting us.


I have not been able to reproduce your issue with the Demo.

Have you identified a scenario to reproduce the issue? 

Which part and configuration are you using?



Best regards,
