Selector: "<item> tag requires a 'drawable' attribute"

I've got the following button:

<Button
            android:id="@+id/searchCompaniesButton"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"          
            android:drawableLeft="@drawable/company_icon"
            android:drawablePadding="10dp"
            android:drawableRight="@drawable/next_icon_big"
            android:gravity="left|center_vertical"
            android:paddingLeft="10dp"
            android:backgroud="@drawable/transparent_button_selector"
            android:paddingRight="10dp"
            android:text="@string/searchCompanies" />

transparent_button_selector is transparent_button_selector.xml in /drawable-ldpi folder:

<?xml version="1.0" encoding="UTF-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@color/lightGrey"
          android:state_pressed="true" />
    <item android:drawable="@color/veryLightGrey"
          android:state_focused="true" />
    <item android:drawable="@null" />
</selector>

Also I've got a colors.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>
 <color name="lightGrey">#3d3d3d</color>
  <color name="veryLightGrey">#4d4d4d</color>
</resources>

But when I run my app, log will say:

'item' tag requires a 'drawable' attribute"

What the hell? I know there are few similar questions, but answers are not helpful. I tried:

If a selector is used to show which items in a list are currently picked then the best answer simply:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/activated_color"  android:state_activated="true"/>
</selector>

Picked items are then determined by the isActivated state if the view.

Why is a transparent background better than the more more direct statement of "no background"?

Your android:background attribute is misspelled:

android:backgroud="@drawable/transparent_button_selector"

The letter 'n' is missing in 'background'

The drawable attribute always takes @drawable.i.e you have to replace

<item android:drawable="@color/..."
      android:state_pressed="true" />

with

<item android:drawable="@drawable/..."
      android:state_pressed="true" />

Use this,

<item
    android:state_pressed="true"
    android:drawable="@drawable/selected_state" />

Then make a shape in drawable folder with name "selected_state" like this.

<shape xmlns:android="http://schemas.android.com/apk/res/android" 
       android:shape="rectangle">
       <solid android:color="@color/lightGrey" />
</shape>

Replace this:

 <item android:drawable="@null" />

with:

<item android:drawable="@color/transparent" />

and add transparent color in your color file with code: #00000000
