Android: Switching to another activity using a button event?

I want to change the current activity to another activity in android using a button. However whenever I click the button, eclipse debug perspective comes up with the error "source not found". This is the function I'm using to change the activity 

public void toManager(){
    Intent i = new Intent(getApplicationContext(), DegreeActivity.class);
    startActivity(i);
}

In my xml file, the button has an onClick listener. This is the xml

<Button
    android:id="@+id/btn_toDegree"
    android:text="@string/btn_toDegree"
    android:textSize="13pt"
    android:layout_centerVertical="true"
    android:gravity="center"
    android:layout_height="wrap_content"
    android:layout_width="fill_parent"
    android:layout_marginLeft="15dip"
    android:layout_marginRight="15dip"
    android:onClick="toManager"  <!-- This line -->
    />

If I call the toManager() function in the onCreate() block of the first activity, It switches to the next activity with no error. However when I try to switch using the button it doesn't work.

Click handler must look like:

public void toManager(View view) {
    Intent i = new Intent(getApplicationContext(), DegreeActivity.class);
    startActivity(i);
}

From Button documentation:

Now, when a user clicks the button, the Android system calls the activity's selfDestruct(View) method. In order for this to work, the method must be public and accept a View as its only parameter.
