I have tried everything I can think of, and it still will not run on the android. Has anyone seen this before, and/or knows how to fix it?

Okay, trying again but paying more attention to the error messages... I see:
Could not find method com.badlogic.gdx.controllers.Controllers.removeListener, referenced from method com.deerandcatgames.spikeJumper.GUI.OuyaTable.dispose
As one of the reasons the link failed. I think you must be using the libgdx "controllers" extension ... you need to add the gdx-controllers-android.jar. See the "Integration Into Your Project" section of the badlogic blog: http://www.badlogicgames.com/wordpress/?p=2724

The gdx.jar (which contains the platform-independent Libgdx classes) probably didn't get packaged into your Android .APK. (Versus the Android-specific Libgdx classes which are packaged in gdx-backend-android.jar and did seem to make it into your .APK.)
You need to make sure your Android project is exporting the gdx.jar. Right-click on your Android project in Project Explorer, select Properties, select Java Build Path, and select the Order and Export tab. Make sure gdx.jar and gdx-backend-android.jar are both "checked" (along with your common project).

Android Mono '/data/data/Mono.Android.DebugRuntime/lib/libmonosgen-2.0.so' not found

I wonder if you can help me with this error.
I am running a fresh fully updated install of windows 7 with
Visual studio 2010 Professional in trial mode.
In Visual Studio I create a new OpenGl Mono for Android Application
using the built in template.
I compile and run the application.
The emulator boots (I am running API_8) EMU.
The application starts and then aborts.
(In the emulator I get a black screen which quickly closes.)
Same thing happens if I do similar using the Mono Develop IDE
and or the other templates.
Here is a dump of the error message (I cannot find much info on google)
It looks like the error is related to the load library fail.
Thanks

The issue is from the newer versions of mono where libmonosgen-2.0 does not get installed automatically. The path that you will see in which it fails is actually a simlink for the library. What you have to do is manually or through a non-mono apk, create the following:
A folder with your package name in /data/app-lib/
in the folder you will have to push the libmonosgen-2.0.so (and libmonodroid.so if needed)
After this is done you have to navigate to data/data/your.package.name and create a simlink from lib -> the folder you created previously. the command to use is ln -s.
I have noticed that in some cases the simlink exists, but is pointing to a false location.
I had to do this manually and it would not survive a factory reset. A colleugue of mine actually did this the non-mono apk path which does everything for him when ever the provisioning app executes on first launch.

Try going to the project properties and turn off "fast deployment". Then manually remove your app from the emu/device, and try again.

Another possibility is that you don't have enough free space on your device. The problem isn't in your package (OpenGLApplication1), the problem is from installing the Mono.Android.DebugRuntime package, as /data/data/Mono.Android.DebugRuntime/lib/libmonosgen-2.0.so doesn't exist.
I would suggest looking through the adb logcat log, and see if something like the following is present:
W/NativeHelper( 98): Failed to cache package shared libs
W/NativeHelper( 98): java.io.IOException: Couldn't create cached binary /data/data/Mono.Android.DebugRuntime/lib/libmonosgen-2.0.so in /data/data/Mono.Android.DebugRuntime/lib
W/NativeHelper( 98): at com.android.internal.content.NativeLibraryHelper.copyNativeBinaryLI(NativeLibraryHelper.java:289)
If messages like the above are present, remove the Mono.Android.DebugRuntime package (adb uninstall Mono.Android.DebugRuntime), remove some extra apps from your device (to free up space), and try re-installing your app from the IDE.
