I'm not quite sure if it's the right place here to post this problem.
I tried to send string message to java in native c++ file,
But something strange happens when I declare a string variable,
when i was doing ndk-build, it failed with this error
error: 'string' was not declared in this scope
then I tried std::string to declare variable,
it failed again with this error:
error: 'string' is not a member of 'std'
I coded in the FrameMarker example native c++ file, would you help me work it out? Thanks!
