I searched Stackoverflow and yes there is so many questions about this topic and this answer guide me : error-inflating-class-unknown-cause
Check your drawable/background_main i.e. the background image of your root layout - the VM runs out of memory when decoding the bitmap. Make the image dimensions smaller.
my state.xml causes the error but i need to use it, i tried to delete FrameLayout and add android:foreground="@drawable/state" to CardView but it didn't help me. But if i disable android:foreground attribute, i have no error .
Actually i am using that state drawable for selectable RecyclerView row. This happens only Android 6.0 emulators. If you want to see screenshot what it looks like in Lolipop and lower: 
So how can i fix this? Thanks for help !
