Cause of, You are used tools:src attribute instead of android:src.

tool:<attributes> = Working only in preview emulator. It just show you Temporary hint.

android:<attributes> = Used for the actual definition that you have defined

for Ex. If you use tool:text within textView. It's only shown like hint as how looks applied theme.

You do not known the diffenrence between tools and android. tools:src="@tools:sample/avatars" is only show on preview of IDE. Change to android:src="@tools:sample/avatars"

Check the document: https://developer.android.com/studio/write/tool-attributes
