My related xml file :

    android:id="@+id/row_note_frame"
    android:foreground="@drawable/state">

 <!-- other layout elements -->

</FrameLayout>
</android.support.v7.widget.CardView>

state.xml :

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

<item android:state_selected="true" android:drawable="@null">
    <shape android:shape="rectangle"  >
        <solid android:color="@color/colorSelected"   />
        <stroke  android:width="2dp" android:color="@color/colorSelectedDark"  />
    </shape>
</item>

<item android:state_selected="false" android:drawable="?attr/selectableItemBackgroundBorderless">
    <shape>
        <solid android:color="@android:color/transparent" />
    </shape>
</item>

</selector>

My build.gradle :

compile 'com.android.support:appcompat-v7:23.4.0'
compile 'com.android.support:cardview-v7:23.4.0'
compile 'com.android.support:recyclerview-v7:23.4.0'
compile 'com.android.support:design:23.4.0'

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 !
