I've started to get complaints from my users about maps instance, launched from my app, resulting in "no results found". I noticed that after the last update of maps ( I dont keep up to date in maps versin), if i try to launch using the intent geo:latitude,longitude?q=latitude,longitude(label), though it will center the map correctly, it will display result not found for most of south america and a few countries on Europe. The strangest thing is that the map activity shows that it is searching for "latitude, longitude". If i manually change the search string to "latitude,longitude" (blank removed) it will find the location. Where should i report this ? The blank is inserted by the intent itself.
If you want to test it, open google maps , and search for example "-23.612, -46.882" and after that search "-23.612,-46.882" and it will work.
