Jai-GAY commented 4 years ago

OK, I got the latest 4.12 version, still, it did not mention where the v come from?

Do you mean the change log from here? If no, could you guide me the change log explanation towards this file changes?

Dear Client Thank you for contacting DJI.

I think the v-> is just a short form of the previous expression. Becasue the previous expression is too long, just fold it to a short form. Their behaviour is the same.

Hopefully our solution can help you. Kindly Regards, DJI Developer Support

I see, then I do not see the necessity to confuse the users where other lines are still using the long form

Anyway. Note that Android does not support the serialization of lambda expressions. What is lambda expression?

I suggest reverting back the codes.
