Get Details of Sensor (Gravity Sensor)

Gravity Sensor:

Gravity Sensor is a unique feature that allows applications to take advantage of the phone's real-world physical position in your hand.Also the Gravity sensor is the ability to play games without using your fingers and u can also move it side to side and it fit to the screen.And programmatically The gravity sensor provides a three dimensional vector indicating the direction and magnitude of gravity.

2. note that:

• you can use SensorManager to find out the available sensors in device and also selected type sensors as I use Gravity Sensor.
• You can get all the details from Sensors as I use Gravity Sensor  
• Learn more about Sensors and multiple types of sensors.

3. conclusion:

• Some information about how to get Description list of device Sensors.
• know what are Sensors and how to use Sensors.
• Know how to Create Alert Dialog with Dynamic Layout.

4. About the post:

• The code seems to explain itself due to comments, but if you have any questions you can freely ask too!
•  Don’t mind to write a comment whatever you like to ask, to know,to suggest or recommend.
•  Hope you enjoy it!

5. Source Code:

        you can download the source code GoogleDrive, Github
