In this video, we will be creating an application in which we will be displaying a simple torch image on clicking on that image we will be switching our flashlight on and off. 
We have seen many applications on play store for torch application. With the help of this application we can enable or disable the flashlight of our android device. We will be using android studio  as an IDE for building this project. 
This video we will definitely help beginner to intermediate level android developers to brush up and enhance their android development skills.
