Caused by android.view.InflateException Binary XML file line #101: Caused by android.content.res.Resources$NotFoundException

Since you don't have help.png in xhdpi folder, that's why you have that error, because xhdpi is associated for 720 X 1280px density (ex: Galaxy J7).

You could put only the xxhdpi picture to no-dpi folder, or put that picture in all the folders.
