Google meddelade idag genom sin blogg för utvecklare att man från och med nu löpande kommer att publicera data över fragmenteringen bland Android-enheter. Detta ger bland annat utvecklare möjlighet att se om det är lönt att satsa på bakåtkompatibilitet för en viss Android-version eller inte.

From a developer’s perspective, there are a number of interesting points on this graph:

• At this point, there’s little incentive to make sure a new application is backward compatible with Android 1.0 and Android 1.1.
• Close to 30% of the devices are running Android 1.5. To take advantage of this significant install base, you may consider support for Android 1.5.
• Starting with Android 1.6, devices can have different screen densities & sizes. There are several devices out there that fall in this category, so make sure to adapt your application to support different screen sizes and take advantage of devices with small, low density (e.g QVGA) and normal, high density (e.g. WVGA) screens. Note that Android Market will not list your application on small screen devices unless its manifest explicitly indicates support for ”small” screen sizes. Make sure you properly configure the emulator and test your application on different screen sizes before uploading to Market.
• A new SDK for Android 2.0.1 was released two weeks ago. All Android 2.0 devices will be updated to 2.0.1 before the end of the year, so if your application uses features specific to Android 2.0, you are encouraged to update it to take advantage of the latest Android 2.0.1 API instead.
