Take Picture with Camera - Android Studio - Java

In this video, we will capture images with Camera using the Camera Intent. The camera will be opened after clicking the button. If an image is captured it will be set to an ImageView.

We will require the following permission: 

1) CAMERA 

2) WRITE_EXTERNAL STORAGE 

So we will also handle Runtime Permission for OS Marshmallow and above.
