We focus on promoting and developing examples for Androids’ Intent system which is designed to promote code re-use. We started this open source project in Dec 2007 to create developer tools and applications showcasing the use of intents. OpenIntents’ open source applications have had over 5 million application downloads from the Android Market (with the most popular, OI File Manager, having over 2.5 million). They are also available via several channels outside of Googles’ Android Market, incuding being pre-installed on devices and community developed ROMs. Our Sensor Simulator application is considered by many an essential developer tool to simulate hardware sensors on the emulator.
