title: Fused Location Manager API Accuracy
body: <p>I want to make an Android app that needs locations accurate to about 1m or less. 
  Is the "Fused Location Manager API" good enough, or can GPS never be this accurate, regardless if fused with other Sensors?
  If so, does anybody know a way to get more accurate locations on a smartphone?</p>
  
  <p>Thank you!</p>
