Getting nullpointer exception : LensEngine LensAnalyzerRunable on using it second time

[rohitgarg29]

Hi,

I am using this example to scan the ID card, it is working fine but when i am trying to scan it 2nd time, it is giving me null pointer exception.

Exception thrown from receiver.
java.lang.NullPointerException: tep oivk* ita ehd'odcmhae.m.ld*.omnMAaye*.banitr*(o.uwihsmskcmo.Lrm)* nanl* betrfrne
at com.huawei.hms.mlsdk.common.LensEngine$LensAnalyzerRunable.run(LensEngine.java:734)
at java.lang.Thread.run(Thread.java:929)

plus any reason for getting below logs

forbiddenHiLog.getVenderCountry=meafnaf
forbiddenHiLog openHa = true

Update: we need below code onPause, that will resolve the issue.
this.lensEngine = null;

I still want to know the reason behind forbidden lines.

Thanks in advance for your help.
