Well, I may be too late to comment on an article that is 2 years old, but it does not work on my old phone running Marshmallow.
I am testing the starter project.

Hello dttt,

It’s never too late! :] That happened, because RELATIVE_PATH is from a newer version of Android, and the images table on the database on Marshmallow doesn’t have that column. My suggestion is to just add a verification like this one:

fun hasAndroid11OrNewer(): Boolean {
  return Build.VERSION.CODENAME >= ANDROID_R
}

To decide when to use RELATIVE_PATH.

Best,
Carlos
