Google Direction Api 🗺️

ℹ️ Library Details :

This is an android library which provides you a direction path between two points (locations) such as device location to destination location. To use this library, you need to create a project on Goolge Cloud Console and enabble the Map SDK along with Google Direction Api. After the all completion of the setup, just follow these simple steps to implement the code in your project.

ℹ️ Implementation Process :

Gradle

Add jitpack repository in your build.gradle (project-level) file :

allprojects {
      repositories {
	...
	maven { url 'https://jitpack.io' }
	}
}

OR

in your settings.gradle

dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        ...
        maven { url "https://jitpack.io" }
    }
}

Add dependency :

Add dependency in your build.gradle (module-level) file :

dependencies {
	  implementation 'com.github.dangiashish:Google-Direction-Api:1.6'
}

in your map activity

public void getRoutePoints(LatLng start, LatLng end) {
       if (start == null || end == null) {
           Toast.makeText(this, "Unable to get location", Toast.LENGTH_LONG).show();
           Log.e("TAG", " latlngs are null");
       } else {
           RouteDrawing routeDrawing = new RouteDrawing.Builder()
                .context(MainActivity.this)  // pass your activity or fragment's context
                .travelMode(AbstractRouting.TravelMode.DRIVING)
                .withListener(this).alternativeRoutes(true)
                .waypoints(userLoc, destLoc)
                .build();
        routeDrawing.execute();
       }

}

⚠ Note : Please restrict your api keys on GCP for your specific android package name

Implement the RouteListener interface class in your Activity/Fragment to override the operations

On Route Failed

@Override
public void onRouteFailure(ErrorHandling e) {
    Log.w("TAG", "onRoutingFailure: " + e);
}

On Route Start

@Override
public void onRouteStart() {
    Log.d("TAG", "yes started");
}
    

On Route Success

@Override
public void onRouteSuccess(ArrayList<RouteInfoModel> routeInfoModelArrayList, int routeIndexing) {
     if (polylines != null) {
         polylines.clear();
     }
     PolylineOptions polylineOptions = new PolylineOptions();
     ArrayList<Polyline> polylines = new ArrayList<>();
     for (int i = 0; i < routeInfoModelArrayList.size(); i++) {
         if (i == routeIndexing) {
             Log.e("TAG", "onRoutingSuccess: routeIndexing" + routeIndexing);
             polylineOptions.color(Color.BLACK);
             polylineOptions.width(12);
             polylineOptions.addAll(routeInfoModelArrayList.get(routeIndexing).getPoints());
             polylineOptions.startCap(new RoundCap());
             polylineOptions.endCap(new RoundCap());
             Polyline polyline = map.addPolyline(polylineOptions);
             polylines.add(polyline);
	  }
     }

}

On Route Canceled

@Override
public void onRouteCancelled() {
    Log.d("TAG", "route canceled")
    // restart your route drawing
}
