android - Cant get Geopoints to add to google map due to; Couldn't get connection factory client -

i getting error while try plot multiple geopoint locations onto google map. reading latitude , longitude mysql database through php , json. have looked @ main examples, such couldn't connection factory client, couldn't connection factory client - fighting google maps, android mapactivity : couldn't connection factory client.
i can confirm not invalid api key have generated 2 different keys , returned same error. not api level problem either, tried run application on api level 17 , on level 8 , still no joy. when run code displays map no problem , gets exception toast message of "error displaying contents"

i appreciate get, in advance.

if have generated these keys recently, not results, because api v1 deprecated , won't work.

you may want switch maps api v2: https://developers.google.com/maps/documentation/android/

don't try use old code, because new api doesn't share code api v1.
