API Google URL pour les retours Android ZERO_RESULTS

Question

Quand je lance la première url API Google avec l'origine, la destination et points de passage, il retourne

https://maps.googleapis.com/maps/api/directions/json?origin=9.6614981,80.02554649999999&waypoints=6.9040322,79.948803&destination=6.053518500000001,6.053518500000001%7C&sensor=false

{ 
    "geocoded_waypoints" : [ 
     {}, 
     {}, 
     { 
     "geocoder_status" : "ZERO_RESULTS" 
     } 
    ], 
    "routes" : [], 
    "status" : "NOT_FOUND" 
} 

Mais quand je lance cette deuxième url, cela fonctionne parfaitement bien.

https://maps.googleapis.com/maps/api/directions/json?origin=6.9146871,79.9711348&waypoint=6.9040322,79.948803%7C&destination=6.9058482,79.9248089&sensor=false

Quelle est la différence lorsque l'on compare les deux URL de, je ne peux pas sembler trouver. S'il vous plaît aider! J'essaie de tracer les routes entre l'origine et la destination à travers un waypoint. Comment puis-je atteindre cet objectif ?? Merci!

Answer 1

Vérifiez votre destination Latlng. Le premier lien vous demande la navigation de Sri Lanka au Nigeria (6.053518500000001,6.05351850000000). Je pense que vous ajoutez une destination de discordance, c'est-à-dire que vous utilisez également la même valeur de latitude pour la longitude. Vérifiez votre code.
