App crashing after adding a ScrollView and ImageView

问题

I added a scroll element to the main activity of my application along with an ImageView but when I ran the project on an emulator it crashes giving me errors stemming from the main activity.The error log is a follows: http://pastebin.com/PAYrjHCL

So from going through the errors I found that it was a problem in the main activity.But I don't see where I have gone wrong as I only added these two features.Can anyone spot whats wrong in this activity thats causing it to crash?

My main_activity is like this:

<ScrollView 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="fill_parent"

    android:fillViewport="true"
    android:gravity="center_vertical"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity"
     >
