Application crashes after an orientation change for no apparent reason

EDIT-Moderator, feel free to delete this question. The problem lay in my background image size, and not the actual orientation change.

Please bear with me- I do not believe this question/problem has been answered in this simple of terms.

I have an application with several activities and 2 layout resources for each with the same name for the XML files, stored in res/layout-land and res/layout-port.

The issue is that when I start the application on a Nexus One (I am using Android 2.3) the application starts with no issues, but if I try to rotate the screen (change the orientation), it crashes. To clarify, if I start the Activity holding the phone landscape style, the application shows me the res/layout-land resource layout, and vice versa, but if I try to change the orientation at runtime, it crashes.

I believe that if there are 2 XML layouts, saved in -port and -land folders then Android should destroy the activity and recreate it with the other layout by the same name, correct?

Here is my manifest, and I am happy to paste in some more code if necessary. 

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="dominion.game"
      android:versionCode="1"
      android:versionName="1.0">
    <uses-sdk android:minSdkVersion="9" />
    <application android:icon="@drawable/icon" android:label="@string/app_name" debuggable="true">
        <activity android:name="dominion.game.DominionMenu"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name="dominion.game.CreateMenu"
                  android:label="@string/app_name">
        </activity>
        <activity android:name="dominion.game.AdvancedMenu"
                  android:label="@string/app_name">
        </activity>
        <activity android:name="dominion.game.ShuffleResult"
                  android:label="@string/app_name">
        </activity>
    </application>
</manifest>

Here is the beginning of the onCreate method:

      @Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.mainmenu);
    //...Lots of onClick listeners for the 4 buttons...
    }

The rest of it is action listeners, and if each button is clicked, it starts an intent to another activity. The mainmenu layout corresponds to res/layout-land/mainmenu & res/layout-port/mainmenu, at least in theory.

I looked at the DDMS errors, but nothing has a link to somewhere in my code where there is an error.

EDIT: error log on request (all of the red stuff until the force close)-

In essence, my question is: What are the steps needed to take in order for automatic screen orientation changes to work? I thought I did them all...

Any help or suggestions are much appreciated, thanks in advance!

@Rahul Sharma- That stopped the crashing, but instead of switching to the other layout, it just uses the same layout in the different orientation.

@Asynkronos I'm on 2.3 not 2.1 but that is an interesting bug to consider, certainly. I don't think I'm using those objects though.

OK- you guys are gonna be annoyed, but the problem was that my background image was enormous- like close to 30in x 30in. So I scaled it down to about 7x7 in inches, and there is no issue...

In your manifest insert android:configChanges="keyboardHidden|orientation|screenSize" in application tag to overcome crash occurrence due to orientation change. This has helped my application.

in your AndroidManifest.xml put

android:configChanges="orientation|keyboardHidden" in all of your activity tags

e.g.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="dominion.game"
    android:versionCode="1"
    android:versionName="1.0">
    <uses-sdk android:minSdkVersion="9" />
    <application android:icon="@drawable/icon" android:label="@string/app_name" debuggable="true">
        <activity android:name="dominion.game.DominionMenu" android:label="@string/app_name" android:configChanges="orientation|keyboardHidden">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name="dominion.game.CreateMenu"
              android:label="@string/app_name" android:configChanges="orientation|keyboardHidden">
        </activity>
        <activity android:name="dominion.game.AdvancedMenu"
              android:label="@string/app_name" android:configChanges="orientation|keyboardHidden">
        </activity>
        <activity android:name="dominion.game.ShuffleResult"
              android:label="@string/app_name" android:configChanges="orientation|keyboardHidden">
        </activity>
    </application>
</manifest>

Hope this helps :-)

I've had similar screen orientation change problems on my Nexus One as well. Perhaps you are encountering this documented bug?

Was happening on my app aswell, check that activities arent being created on Orientation change or something. Its to do with the activity lifecycle for sure
