    Hi,

    is there any limit for the size of the UnitySendMessage() parameters? Want to pass JSON content up to 1 KB... Will that work?

    Thx,

    Ekki

    Hi Ekki,
    I am also checking whether any limitation for UnitySendMessage() parameters. Did you have any information on this?
    Thanks,
    Soumya

    There are no well defined limitations.

    Hi
    UnitySendMessage() allows only strings right? any other mechanism for communication from java to UnityLibrary?
    Thanks,
    Soumya

    Thank you Aurimas-Cernius.
    This from Unity to Java and the callback. Right? I hope there is also no size limitations. It would be great if you have any sample project link that includes java part also.
    Thanks in Advance

    Have a look at code sample provided in documentation. It contains AndroidJavaClass and AndroidJavaObject which let you create Java objects and call methods on them, while AndroidJavaProxy lets you implement Java interface in C#, giving ability to call back.
