Gmail for Android has just been updated to include some fancy new features which are good for both developers and users.
Users of Honeycomb will be upgraded to the same experience as users of Ice Cream Sandwich, which is a good start.
But, the more interesting news is the introduction of an official API to access your GMail account. It assumes like using the API will request the user to accept this access as a popup (like you see with apps like Google Chrome to Phone wanting access to Push) which cures the older “API” which meant any app could access all of your email at once with just a permission.
This means all of our cool Gmail widgets/notifiers can now be fixed and made to work properly! So, developers get coding to implement this back into your apps! (Documentation is over on the Android Dev blog, including sample code etc)
