let me quote the SDK-Documentation:
Object android.content.Intent.getExtra(String name)
public Object getExtra(String name)
Retrieve extended data from the intent.
name The name of the desired item.
the value of an item that previously added with putExtra() or null if none was found.
You see that it refers to the method "putExtra(String, Object)
Don't start searching, it does not exist
You'll have to use so called Parcelable
s (Interface), to write complex objects.
Like described here: http://www.anddev.org/viewtopic.php?p=3875#3875
: Parcelable currently do not work with the Eclipse plugin
(untested but foudn in the SDK-documentation)
Maybe it changed with now works with m5
