Thank you for the gist! Very helpful.
Hey bro can you please tell me the type of imagePickerListener in if check of onActivityForResults in activity? and where we declare this variable?
Hi, nice work.However, got "TransactionTooLargeException" in oreo when, any idea how to fix it?, this issue shows up when I click a button to show the image picker dialog
