Analysis: Suppress toast deprecated warnings for debug source

Warning Messages:
- "'getter for view: View?' is deprecated. Deprecated in Java"
- "'setColorFilter(Int, PorterDuff.Mode): Unit' is deprecated.
Deprecated in Java"

These deprecated warnings are suppressed, that is, instead of being
resolved, since a resolution would require a proper migration to
snackbar (from toast).

For more info see:
- android.widget.Toast.getView (Docs):
https://developer.android.com/reference/android/widget/Toast#getView()
- android.graphics.drawable.Drawable.setColorFilter (Docs):
https://developer.android.com/reference/android/graphics/drawable/
Drawable#setColorFilter(int,%20android.graphics.PorterDuff.Mode)
