“How to” guides are plentiful online, and many of them are quite helpful. The problem is that many are also written by people who have little or no idea what they’re doing, and so developers may be happy to know that a new “Twitter for Android” guide comes straight from Google.
For the sake of showcasing some best practices, seven different patterns were put together to cover seven different app screens. The first three are “Contacts Sync with Address Book at Sign in,” “Twitter account integration with QuickContact for Android,” and “Dashboard.”
Then things pick up with “Action Bar,” “Search Bar,” “QuickActions,” and “Companion Widget.”
This should give developers a good idea of what Google considers a well-constructed and useful app. And considering that Google pretty well knows its stuff – witness its market cap of about $165 billion- following the guidelines is likely to work out in developers’ best interest.
