Getting nullpointer exception : LensEngine LensAnalyzerRunable on using it second time #52

Open rohitgarg29 opened 3 years ago

rohitgarg29 commented 3 years ago

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.

@rohitgarg29 Please firstly check which integration way you are using

  1. Full SDK integration: only one dependency needs to be added, and upgrade ml-computer-card-icr-cn to the latest 2.0.3.300 version，
  2. Basic SDK integration: only one dependency needs to be added, adn upgrade ml-computer-card-icr-cn-plugin to the latest 2.0.3.300 version
