Introduction to the concept and principle of pedometer sensorAndroid KitKat have added a few more hardware sensors to it ' s API list. Step sensors is one of them, which looks very promising. Although, not a lot of phones yet has these Step sensors, in the future, this would gradually become a standard I think. Currently, Nexus 5 has them.Step Counter:this keeps a count of the number of steps that is taken. The counter is only reset when you re-boot t
IOS pedometer and ios Pedometer
This blog introduces the popular "pedometer"-simple knowledge points.
The implementation of the pedometer is changed at the beginning of ios8.
However, I will give a brief introduction to the previous sections.

Today I wanted to say that the dropdown in the ListView refreshed the data, but suddenly thought of some better ideas.It took a day to make changes to the network functions, photos, and some logical functions of this project, so it is necessary to pedometer that the previously downloaded pedometer program may not work.Pedometer (pedometer) the entire project sour

1, first download the pedometer, and then click Open, as shown below.

3. The pedometer is changed with the dynamic of our running. We can click on the phone in the lower left corner of the "three", click Pause, as shown below

Pedometer as an algorithm function module, this should be separated from the business module, decoupling. This can also be more focused on the upgrade of the algorithm. Let me briefly describe the implementation principle of the pedometer algorithm, and give us some inspiration.1. AlgorithmsFor all pedometer, the first step was to use an accelerometer (Accelerome
With the improvement of people's living standards, coupled with the rapid development of mobile technology, more and more software into the health industry, pedometer is used to record the personal movement of a very good technology. This period of time out of curiosity about this technology, learn to learn the steps of the implementation process.There are two ways to implement the pedometer, (1), directly

Cmpedometer: can access user activity (can access the step data) applicable to iOS8 above the system iOS can see the following description
HealthKit: A health application in the iOS system needs to be licensed to access health data (such as steps)
What's the difference between these two?
In fact, HealthKit is also the use of Cmpedometer to read the user's steps and mileage, of course, the calculation method is in the phone's internal calcula

Today, it is not intuitive to say that the indicator slides along the interface. I will first attach several images:
