I found several examples where this expression is used:
B4X:
Dim mp As MultipartFileData
But I didn't find any reference to any library or class which I have to add to my project to avoid compilation errors.
Can someone give me an idea........?
What I think @Erel meant was, if you type MultipartFileData into the forum search box then the first item in the search results is the one that he shows here. But I know what you mean - all of us sometimes miss what others think is obvious.
Indeed!
But unfortunately I had ignored the headline where you can see the reference to "OkHttp".
So I continued reading the context looking for a library reference.
S...t happens!
