Actually, I have no idea why I have this error.
Follows the code hoping that there is everything useful for a diagnosis.
The structure of the app is a standard Navigation Drawer Activity
with a Fragment
inside. The Fragment
has a RecyclerView
.
The device used is Motorola XT1068 (Android 6.0, API 23).

UPDATE
One of the answers suggests that the problem could be related to getAllItems(). But resources invoked seem to be correctly loaded.
Resource ID. A unique resource name for the element, which you can use to obtain a reference to the ViewGroup from your application. See more about the value for android:id below. android:layout_height.
Resources are the additional files and static content that your code uses, such as bitmaps, layout definitions, user interface strings, animation instructions, and more.
Resource Manager is a tool window for importing, creating, managing, and using resources in your app. You can open the tool window by selecting View > Tool Windows > Resource Manager from the menu bar or by selecting Resource Manager on the left side bar.
Your problem is the wrong placement of resources(images). You use (API 23) but resources for API 23 is null, because they only API 24 and up.
Now all images marked (v24) this means that they are in drawables-v24 just move in drawable
that'll solve your problem.
