Next we will use an example to describe how to access the accelerometer through layer-based accelerometer events. As shown in this example, there is a ball in the scene. When we place the mobile device horizontally, the screen is up, and then shake the mobile device left and right to change the position of the ball. Next let's take a look at the specific program code. First, let's take a look at the hellow

or devices. For example, the getResolution and getMaximumRange () methods can be used to obtain the sensor's recognition rate and maximum measurement range, and the getPower method can also be used to obtain the power requirements of the sensor. Two public methods are particularly useful if you want to optimize your applications for sensors of different manufacturers or for sensors of different versions. For example, if your application needs to moni

Android --- 57 --- sensor, android Sensor The Android system provides support for sensors.Developing an application sensor is simple. You only need to register a listener for the specified listener. Steps:1. Call the getSystemService (Context. SENSOR_SERVICE) method of Context to obtain the SensorManager object. The SensorManager object represents the system's

This time we have studied the development of Android sensors, previously introduced, tween use, so we can combine sensors with tween animation, develop a simple compass.First of all, introduce the sensor knowledge,in the the use of sensors in Android applications depends on the Android.hardware.SensorEventListener interface. This interface allows you to monitor various events of the sensor. The code for th

My Android advanced tour ------> Android uses Sensor (Sensor) to implement the level function. The level here refers to a more traditional bubble level, filled with liquid in a transparent disc, with a bubble in the liquid. When one end is tilted, this bubble will float at one end.The first parameter returned by the Direction sensor is used to implement a compas

In this lesson, we will learn the wirelessly light sensor, please bypass this article.The Android system has a feature that automatically adjusts the brightness of the screen. It detects the light intensity of the environment around the phone and adjusts the brightness of the phone's screen accordingly to ensure that the screen can be seen clearly, whether in strong or weak light.Said too much theory is a bit virtual, here Direct combat practical ligh

Sensors on the Android platform include the accelerometer, orientation, magnetic field, and light ). The development of sensor applications on the Android platform is implemented through the listener mechanism. The main steps to develop applications for one or more sensors are as follows: 1. Create a sensormanager object 2. Implement the sensorlistener Interface This is the main task of developing

I. Introduction to Functional Parameters Bosch Sensortec's latest BMI160 inertial measurement unit integrates the most advanced 16-bit 3-axis ultra-low-G and ultra-low-power 3-axis gyroscopes into a single package. The MI160 is available in a 14-pin LGA package with a size of 2.5x3.0x0.8mm3. When the accelerometer and gyroscope operate in full-speed mode, the power consumption is typically as low as 950µa, which is only 50% or less of the power consum
