Google Place API Example

In this tutorial i am going to show you how to integrate Google Place API in your android project, please follow below steps:

First of all we need Place API, before creating android project here i am going to show how to get Place API:

1. Login with https://code.google.com/apis/console/?pli=1



2. Create New Project with Google Place API Example
 

3. Click on Services and activate Place API service 



4. Click on API Access and note down API key



Now you have API with you now create a Project in android with Google Place API Example and follow below code:


activity_main.xml
