I am developing an app that gets current latlongs of a device and stores them in a file in a new line. I ran my app on kit kat version 4.4.4 and on marshmallow version 6.0.1. I took both device in my car for testing and took a long ride around the city. I noticed a weird output, the file generated from kit kat had 576 lines means that 576 pair of latlongs were recorded. But in the file generated on marshmallow device had only 250 lines of latlongs. As long as I know, according to the definition of Doze mode introduced in marshmallow, the phone only enters doze mode when the device is stationary. But in my case the device was not stationary because it was in a moving car. I am confused. Can anyone help.
Below is my Background Service Class without file saving code.
