Please help.


@Sankalp, was it solved somehow?


Hey @Sankalp

were you able to solve the issue yet ?


Anybody got a solution for the issue in question?
@pabitrapadhy @vedi @Sankalp @SonarSystems @slackmoehrle @energyy @yinjimmy @nite

I am having the same issue.
As far as I understand, the call sequence is something like -> UserDefault::getInstance() ---> initXMLFilePath() --> getPackageNameJNI() and crash. There seems to be some difficulty while making call to Java from C++ through JNI.

FYI, this is working for some UserDefault keys and crashing for some others.


Can you post the stack trace for the crash?

@nite, btw I have resolved this issue by not calling/utilizing UserDefault (to save or retrieve key-data) in a constructor of any class (the classes which I defined).

For example, in my previous message “Backtrace” on this thread, you can notice that UserDefault is called from Player class constructor. To resolve this issue, I moved the UserDefault call to another function Player::Initialize which is called after the object of player is created. And this resolved the issue for me.

I am using cocos2d-x v3.10.
