I have android app,I want to calculate the distance for every two minutes when the user click start button.So I have Service class in my application ,in that class I have googleapiclient.
So I'm getting location for every two minutes I'm adding that distance in sharedpreference but mobile goes to sleep mode means ,distance is not calculating when user click ends button .
I think service get stopped.Please help me to fix my issue. What I have to do when mobile goes to sleep mode,If i calculate distance in activity page means when application is in background distance wont calculate, that's why I'm adding distance in service.
