Error inflating class ImageView - Unable to find resource

[Zahra Jamshidi]

I generated icons using this great tool and put it in "res" folder of my app. Today I received some crashes with the following logs:

when I checked the R.java file the resource id is for ic_action_share, which already exists in drawable folders:

and here is how I used the image:

     <ImageView
                android:id="@+id/app_share_menu"
                android:layout_width="32dp"
                android:layout_height="32dp"
                android:layout_alignParentEnd="true"
                android:layout_centerVertical="true"
                android:background="@drawable/btn_bg_ripple"
                android:src="@drawable/ic_action_share" />

The app works well on my test devices but some users have problems with it. Do you have any suggestions how to fix it?

Hm, I really don't see how the tool can be at fault here... have you tried using other PNGs? I get the sense there's something in your code..
