1. Run a sample project.
2. Swipe ImageView left and right.
3. See app crashes with one of the following:

System.ObjectDisposedException: Cannot access a disposed object. Object name: 'Android.Widget.Toast'.
System.ObjectDisposedException: Cannot access a disposed object. Object name: 'Android.Graphics.Matrix'.
System.ObjectDisposedException: Cannot access a disposed object. Object name: 'Android.Views.GestureDetector'.

then:
4. open /objdisposed/environment.txt and change it's contents to:
MONO_GC_PARAMS=bridge-implementation=new
or
MONO_GC_PARAMS=bridge-implementation=old
5. Clean project.
6. Run project again.
7. Make sure bridge implementation has switched to new (or old), i.e. see GC_NEW_BRIDGE tag in console:
[Mono] GC_NEW_BRIDGE num-objects 15.....
8. Swipe ImageView left and right.
9. See app runs okay.
