If you are directly in this tutorial I recommend you to follow Google Maps Android API Getting Started Tutorial: Part 1 before going through this because this is continuous tutorial after that.

Android Example: How to Display Specific Location in Google Map using V2 API

In the previous tutorial we had displayed default google map in android application and here we will customize little bit and add map cursor to our location and add some text.

Open your MapsActivity.java file of Google Maps Android API project and add a line of java code mMap.setMyLocationEnabled(true); under onMapReady method. Change the line LatLng sydney = new LatLng(27.746974, 85.301582); with your location latitude and longitude. Replace 27.746974 with your latitude and 85.301582 with longitude. In this tutorial, I have used the latitude of Kathmandu, Nepal you can use your own. MapsActivity.java file will look like below.

src/MapsActivity.java

All other files are same that as previous. We don’t need to change other files to display current location in google map.

Video Demo


Now run your Get Current Location - Google Maps Android API Tutorial: Part 2 application, you will see a cursor in google map with your current location. If you click on the cursor some texts appears that we place in our java activity file.
