Http request using HttpClient giving errors

Using Arduino Programming Questions

I am trying to do http request using httpClient.h . But ended up in following errors. Any suggestions please.

Arduino: 1.8.9 (Windows 10), Board: "Arduino Mega ADK"

This is the first thing you need to resolve. You downloaded a library called HttpClient, when you already had one supplied with the IDE. Why?

Bridge library is not a HttpClient library. Bridge is for Yun

Then why does the IDE think that there is a copy of the HttpClient library in that folder?

there is a file named HttpClient.h and the library.properties file doesn't specify 'library detection' .h files
