Question

In Android Studio, I just can't find the errors to this problem, I have the following code written down, what I need is just how to make a direct route/directions between 2 specific coordinates, specifically I need the coordinates (34.782, -86.569) to have a direct route to (34.781, -86.571) thank you

Here is Code:

package com.example ------

import android.support.v4.app.FragmentActivity;
import android.os.Bundle;

import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.OnMapReadyCallback;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {

    private GoogleMap mMap;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_maps);
        // Obtain the SupportMapFragment and get notified when the map is ready to be used.
        SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
                .findFragmentById(R.id.map);
        mapFragment.getMapAsync(this);
    }


    /**
     * Manipulates the map once available.
     * This callback is triggered when the map is ready to be used.
     * This is where we can add markers or lines, add listeners or move the camera. In this case,
     * we just add a marker near Sydney, Australia.
     * If Google Play services is not installed on the device, the user will be prompted to install
     * it inside the SupportMapFragment. This method will only be triggered once the user has
     * installed Google Play services and returned to the app.
     */
    @Override
    public void onMapReady(GoogleMap googleMap) {
        mMap = googleMap;

        // Add a marker in Sydney and move the camera
        LatLng sydney = new LatLng(-22, 115);
        mMap.addMarker(new MarkerOptions().position(sydney).title("This is not AAMU"));
        mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));
        mMap.addMarker(new MarkerOptions()
                .position(new LatLng(34.782, -86.569))
                .title("Where the hell am I?"));

          

PolylineOptions lineOptions = new PolylineOptions();
//create lat lng object
LatLng ll1 = new LatLng(34.782, -86.569);
LatLng ll2 = new LatLng(34.781, -86.571);
//add both lat lng to line options
lineOptions.addAll(new ArrayList<LatLng>(){ll1,ll2});
mMap.addPolyline(lineOptions); //add line to map

    }
}
