Question

I am trying to follow the tutorial at This Link and I get the following errors

[2012-10-03 22:02:16 - MyFirstApp] res\layout\activity_main.xml:0: error: Resource entry activity_main is already defined.

I have the following code in my activity_main.xml

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal" >

    <EditText android:id="@+id/edit_message"
        android:layout_weight="1"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:hint="@string/edit_message" />

      <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/button_send" />         
</LinearLayout>

Could anyone please tell me what is going wrong. I have spend a significant time trying to figure this issue out. Is there something wrong with the configuration ? When I click the run button a file called activity_main.out.xml gets created which is empty.

You are trying to run the xml file activity_main. Change the focus to any java file or run it from package explorer by right clicking the project and run it. Before doing all this, delete your activity_main.out file.
