ANDROIDS ARE ALIVE. THEY CAN LOCATE THEMSELVES, see, listen, and understand speech. They can sense radio signals and detect orientation, movement, and environmental properties. Can your computer do all of that?

The availability of sensors is one feature Android devices have that makes them different from other computers. Without sensors, an Android device is just an underpowered, mobile web browser with a screen that is too small and has an awkward input mechanism.

Sensors also allow apps to do amazing things. For example, sensors can help save users from painfully slow manual input and manipulation, and sensors can help users do tasks that they could never do before. Because of this, it may be essential for an app to incorporate sensors to be successful.

Sensors will continue to be an important part of the Android platform. As the hardware specifi cations of Android devices improve, so do the number of available sensors and their quality. While this happens, users will continue to expect apps to use any existing and new sensors when possible. Therefore, using Android’s sensors is a crucial skill for any Android programmer to master. This book gives you the knowledge and code you need to develop this skill and make great apps that use sensors.

Learn to build human-interactive Android apps, starting with device sensors

This book shows Android developers how to exploit the rich set of device sensors—locational, physical (temperature, pressure, light, acceleration, etc.), cameras, microphones, and speech recognition—in order to build fully human-interactive Android applications. Whether providing hands-free directions or checking your blood pressure, Professional Android Sensor Programming shows how to turn possibility into reality.

The authors provide techniques that bridge the gap between accessing sensors and putting them to meaningful use in real-world situations. They not only show you how to use the sensor related APIs effectively, they also describe how to use supporting Android OS components to build complete systems. Along the way, they provide solutions to problems that commonly occur when using Android's sensors, with tested, real-world examples. Ultimately, this invaluable resource provides in-depth, runnable code examples that you can then adapt for your own applications.

  • Shows experienced Android developers how to exploit the rich set of Android smartphone sensors to build human-interactive Android apps
  • Explores Android locational and physical sensors (including temperature, pressure, light, acceleration, etc.), as well as cameras, microphones, and speech recognition
  • Helps programmers use the Android sensor APIs, use Android OS components to build complete systems, and solve common problems
  • Includes detailed, functional code that you can adapt and use for your own applications
  • Shows you how to successfully implement real-world solutions using each class of sensors for determining location, interpreting physical sensors, handling images and audio, and recognizing and acting on speech

Learn how to write programs for this fascinating aspect of mobile app development with Professional Android Sensor Programming.

Atmospheric Monitoring With Arduino: Building Simple Devices to Collect Data About the Environment
Atmospheric Monitoring With Arduino: Building Simple Devices to Collect Data About the Environment
We as a species are probably a little bit smarter than fish: at least we know that we spend our lives “swimming” at the bottom of an ocean of air. About 4/5th of that ocean is the relatively harmless gas nitrogen. Around another 1/5 of it is the highly reactive and slightly toxic gas oxygen. The...
