I'm not sure in which context that you are using this selector, but apply to a button it works fine:

layout/Main.axml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <Button
        android:id="@+id/myButton"
        android:layout_width="200dp"
        android:layout_height="wrap_content"
        android:background="@drawable/bg_selector"
        android:text="StackoverFlow" />
</LinearLayout>

drawable/bg_selector (your axml):

<?xml version="1.0" encoding="UTF-8" ?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
    <shape>
      <solid
          android:color="#ef4444" />
      <stroke
          android:width="1dp"
          android:color="#992f2f" />
      <corners
          android:radius="6dp" />
      <padding
          android:left="10dp"
          android:top="10dp"
          android:right="10dp"
          android:bottom="10dp" />
    </shape>
</item>

This is NOT an answer. You can leave a comment saying that it works fine in your part or that you cant reproduce the error. How on earth your answer can help me that have the same problem! — γηράσκω δ' αεί πολλά διδασκόμε, Mar 08 '17 at 19:56
@γηράσκωδ'αείπολλάδιδασκόμε that selector applied to the **background** of a Button works (it is valid syntax for a selector for that usage), applied elsewhere it may not, depends upon the context — SushiHangover, Mar 08 '17 at 20:03
The problem was that two schema files were missing from the schema folder in visual studio. — γηράσκω δ' αεί πολλά διδασκόμε, Mar 08 '17 at 20:10

Nothing worked for me. But I started a new project and started to copy and paste the same code from the old project and it worked. Try it may be this is the only possible solution.
