Error in Android Export

I have this problem when I try to export my 2D Game to Android in Unity:

 Error building Player: CommandInvokationFailure: Failed to re-package resources. See the Console for details.
 C:\Users\Usuario\Games Android\adt-bundle-windows-x86-20130219\sdk\build-tools\20.0.0\aapt.exe package --auto-add-overlay -v -f -m -J gen -M AndroidManifest.xml -S "res" -I "C:/Users/Usuario/Games Android/adt-bundle-windows-x86-20130219/sdk/platforms/android-20\android.jar" -F bin/resources.ap_ --extra-packages com.facebook.android -S "C:\Users\Usuario\Documents\New Unity Project 8\Temp\StagingArea\android-libraries\facebook\res"

And after this, the console show these problem infinite times.

 count <= std::numeric_limits<UInt16>::max()
 UnityEditor.DockArea:OnGUI()

 maxVertices < 65536 && maxIndices < 65536*3

I have no idea how to solve this. Sorry if my English is bad.
