Pick an Image from the Gallery – Android Studio - Java

How to Pick an Image from the Gallery?

In this video, we will pick an image from Gallery on Button click and set that image to an ImageView. 

For this, we will also handle Runtime Permission for READ_EXTERNAL_STORAGE if the system OS is Marshmallow or above. If you want to learn to pick Multiple Images from Gallery you can check for Java OR Kotlin.
