Device Year Class is an Android library that implements a simple algorithm that maps a device's RAM, CPU cores, and clock speed to the year where those combination of specs were considered high end. This allows a developer to easily modify application behavior based on the capabilities of the phone's hardware.

Mappings as of this writing (RAM is a ceiling):

Download the latest JARs or grab via Gradle:

compile 'com.facebook.device.yearclass:yearclass:2.1.0'

or Maven:

<dependency> <groupId>com.facebook.device.yearclass</groupId> <artifactId>yearclass</artifactId> <version>2.1.0</version> </dependency>

Calculating the current device's Year Class is simple.

intyear = YearClass.get(getApplicationContext());

Then, later on, you can use the year class to make decisions in your app, or send it along with your analytics.

if (year >= 2013){// Do advanced animation } elseif (year > 2010){// Do simple animation } else{// Phone too slow, don't do any animations }

See the yearclass-sample project for more details.
