"No XML content. Please add a root view or layout to your document."
<p>I am trying to follow this tutorial : <a href="http://developer.android.com/training/basics/firstapp/building-ui.html" rel="nofollow">http://developer.android.com/training/basics/firstapp/building-ui.html</a> as I am new to android developing and this is what my "activity_main.xml" file looks like :</p>

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="horizontal"&gt;

&lt;EditText android:id="@+id/edit_message"
    android:layout_weight="1"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:hint="@string/edit_message" /&gt;

&lt;Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/button_send" /&gt;
</code></pre>

<p></p>

<p>When I click run I get an error that says "No XML content. Please add a root view or layout to your document." and I noticed there is a new file generated called "activity_main.out.xml". What could I be doing wrong?</p>
