title: Android activity Binary XML file line : You must supply a layout_width attribute
body: <p>I've read about it already, but still it's here.</p>
  
  <pre><code>&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:tools="http://schemas.android.com/tools"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  android:orientation="vertical"
  tools:context=".TaskEditActivity" &gt;
  </code></pre>
  
  <p>So, the exception <code>java.lang.RuntimeException: Binary XML file line #34: You must supply a layout_width attribute.</code></p>
  
  <p>Attribute is there, schema too...
  Solution?</p>
