Google has released the official Google Reader Android application.
It automatically syncs with your Google Reader account and offers almost all features available on desktop such as unread post counts, sharing, commenting, liking and more. In addition the app also allows synchronization with multiple accounts, if desired.
Users can also search RSS feeds by keyword, track keyword searches, follow blogs and profiles on various social sites, and easily share content with friends. It also has an ability to use volume keys for article navigation and the option to enable plug-in content in-line. This means, it can display content such as videos directly in the reader.
The Google Reader app is now available as a free download from the Android Market.
