Android sensors framework
At the moment, it would be best if you read the code to understand what you would need to do. Phone position during a call. The sensor framework reports data through sensor events, and several factors influence the rate at which your application receives sensor events. To identify the sensors that are on a device you first need to get a reference to the sensor service. I assume you had created your AVD while doing environment setup. This class also provides several sensor constants that are used to report sensor accuracy, set data acquisition rates, and calibrate sensors. Monitoring air pressure changes. Table 1 summarizes the sensors that are supported by the Android platform. Sensor Framework You can access these sensors and acquire raw sensor data by using the Android sensor framework.
As a best practice, you should specify the largest delay that you can because the system typically uses a smaller delay than the one you specify that is, you should choose the slowest sampling rate that still meets the needs of your application. Introduction to Sensors The Android sensor framework lets you access many types of sensors. You android sensors framework also determine whether a specific type of sensor exists on a device by using the method and passing in the type constant for a specific sensor. These sensors are capable of providing raw data with high precision and accuracy, and are useful if you want to monitor three-dimensional device movement or positioning, or you want to monitor changes in the ambient environment near a device. The android platform supports three broad categories of sensors.
Also, a device can have more than one sensor of a given type. All our code is available under the GNU Lesser GPL 3. This category includes orientation sensors and magnetometers. You should not have to change android sensors framework sampling rate delay once you set it. If you want to implement further sensors or interfaces, please do so. This example displays the raw sensor data in a that is defined in the main. Software-based sensors are not physical devices, although they mimic hardware-based sensors. The android platform supports three broad categories of sensors. The default data delay is suitable for monitoring typical screen orientation changes and uses a delay of 200,000 microseconds.

Hardware Measures the ambient air pressure in hPa or mbar. Software-based sensors are not physical devices, although they mimic hardware-based sensors. The following might help you with that. If a default sensor does not exist for a given type of sensor, the method call returns null, which means the device does not have that type of sensor. In this case the system invokes the method, providing you with a reference to the object that changed and the new accuracy of the sensor. See our and for details.
This category includes barometers, photometers, and thermometers. Handling Different Sensor Configurations Android does not specify a standard sensor configuration for devices, which means device manufacturers can incorporate any sensor configuration that they want into their Android-powered devices.
