 <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

Code for MainActivity.java file.

import android.os.Bundle;
import com.google.android.gms.maps.CameraUpdateFactory;

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.fragmentMap);
        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;

        // Copy your latitude & longitude here .
        LatLng ECBcollege = new LatLng(28.0600392, 73.2927772);

        mMap.addMarker(new MarkerOptions().position(ECBcollege).title("Engineering College Bikaner"));

        mMap.moveCamera(CameraUpdateFactory.newLatLng(ECBcollege));
    }
}
