Take Picture With Camera - Android Studio - Java

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

We will require following permission: 

1) CAMERA 

2) WRITE_EXTERNAL STORAGE 

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