The Google Android Roadmap for 2011

Android 2.3 (Gingerbread) is the current version of the Google Android operating system designed for mobile phones. It is optimized to operate with a 3.2-inch to 4-inch screen with a screen resolution of 320 x 480 or 480 x 800.

We expect on more update this year: Android 2.4. Android 2.4 will allow single core handsets on 2.4 to use apps developed for dual core Honeycomb 3.0. Other than this we do not expect to see very many differences between 2.3 and 2.4, which is why they both have the same Gingerbread codename. There could be a Android 2.5 and later releases. This is what we expect to be designed for use single core handsets for the next two to three years.

Android 3.1 (Honeycomb) is the current version of the Google Android operating system designed for tablets. It is optimized to operate with a 10.1-inch screen with a 1280 x 800 screen resolution. Android 3.2 (Honeycomb) is a modified version of Android 3.1 optimized to work on 7-inch screens with a 1280 x 800 screen resolution. We do not expect to see very many differences between 3.1 and 3.2, which is why they both have the same Honeycomb codename.

Android 4.0 (Ice Cream Sandwich) will replace Android 3.x in tablets, and Android 2.3/2.4 on dual core phones, by the end of the year. This will bring full dual core support to Android Mobile phones and will be designed to work optimally on 4-inch to 10-inch screens. We expect that it will be designed to work primarily with qHD (540 x 960) to HD screens (1280 x 720 to 1920 x 1080).

We expect that Android 4.0, will drop the need for the home, menu and back buttons, with all controls save power and volume being on the touchscreen.
