Photo gallery testing

I have been researching how to create an image view where the user can add an image from their phone gallery, and I need to have permission to access the users photo album so once the permissions have been accepted on the user end, the application will now have access to the phones gallery and the user can choose any photo and it will be input into the image view on the diary view screen. I have managed to do this however because I am working with an emulator, I was not able to test it so with help from my partner, he was able to help me with this and we both were able to get it working!

Here is a clip of my partner testing the photo gallery on his phone:
