I am just a beginner in the application development industry. I know the accelerometer can be used to return the current acceleration along three axis in meters per second squared (m/s2). But I have come to know that an accelerometer can also be use as speedometer.
I want to know how I can use accelerometer to determine distance traveled by Android device between points of interest. If it is possible, then how can I implement it? I have seen a similar question "how do I measure the distance traveled by an Iphone using accelerometer" How do I measure the distance traveled by an iPhone using the accelerometer?. But I didn't come to a point.
Thank You, Arslan

The sensors that are used to measure distance are accelerometer and GPS. For measuring distance, accelerometer will provide more details or information than GPS, in the other hand, GPS has some restrictions, such as points, signals, data resolution and sampling rate.
AccelerometerSensor. This component senses the Android device's accelerometer, which detects shaking and measures acceleration in three dimensions. Acceleration is measured in SI units (m/s 2 ).
In general, the accelerometer is a good sensor to use if you are monitoring device motion. Almost every Android-powered handset and tablet has an accelerometer, and it uses about 10 times less power than the other motion sensors.
An accelerometer is a device that measures the vibration, or acceleration of motion of a structure.
You get position by integrating the linear acceleration twice but the error is horrible. It is useless in practice.
Here is an explanation why (Google Tech Talk) at 23:20. I highly recommend this video.
