Change the AddPlaces method in GooglePlaces.java and the buildInput method within Places.java

Hello,

According to https://developers.google.com/places/documentation/actions#PlaceReports, the add places extraParams should not be put into the URL as the URL only takes in one param, which is the key. The extraParams should go into the Post Body instead. I have written the code below for you to see.

Please have a look.

Thanks!
