Read the Daily Step Total

This section demonstrates reading current daily step count data using the Fit Android API and Fit REST API.

Android

Your app can read the current daily step total by calling HistoryClient.readDailyTotal , as shown in the following example:

 Fitness 
 . 
 getHistoryClient 
 ( 
 this 
 , 
  
 GoogleSignIn 
 . 
 getAccountForExtension 
 ( 
 this 
 , 
  
 fitnessOptions 
 )) 
  
 . 
 readDailyTotal 
 ( 
 DataType 
 . 
 TYPE_STEP_COUNT_DELTA 
 ) 
  
 . 
 addOnSuccessListener 
  
 { 
  
 result 
  
 - 
>  
 val 
  
 totalSteps 
  
 = 
  
 result 
 . 
 dataPoints 
 . 
 firstOrNull 
 () 
 ?. 
 getValue 
 ( 
 Field 
 . 
 FIELD_STEPS 
 ) 
 ?. 
 asInt 
 () 
  
 ?: 
  
 0 
  
 // Do something with totalSteps 
  
 } 
  
 . 
 addOnFailureListener 
  
 { 
  
 e 
  
 - 
>  
 Log 
 . 
 i 
 ( 
 TAG 
 , 
  
 "There was a problem getting steps." 
 , 
  
 e 
 ) 
  
 } 

The daily total is computed from midnight of the current day on the device's current timezone.

To get the same daily step count as the Fit app, create a data source using the com.google.android.gms app package, as shown in the following example:

 val 
  
 startTime 
  
 = 
  
 LocalDate 
 . 
 now 
 (). 
 atStartOfDay 
 ( 
 ZoneId 
 . 
 systemDefault 
 ()) 
 val 
  
 endTime 
  
 = 
  
 LocalDateTime 
 . 
 now 
 (). 
 atZone 
 ( 
 ZoneId 
 . 
 systemDefault 
 ()) 
 val 
  
 datasource 
  
 = 
  
 DataSource 
 . 
 Builder 
 () 
  
 . 
 setAppPackageName 
 ( 
 "com.google.android.gms" 
 ) 
  
 . 
 setDataType 
 ( 
 DataType 
 . 
 TYPE_STEP_COUNT_DELTA 
 ) 
  
 . 
 setType 
 ( 
 DataSource 
 . 
 TYPE_DERIVED 
 ) 
  
 . 
 setStreamName 
 ( 
 "estimated_steps" 
 ) 
  
 . 
 build 
 () 
 val 
  
 request 
  
 = 
  
 DataReadRequest 
 . 
 Builder 
 () 
  
 . 
 aggregate 
 ( 
 datasource 
 ) 
  
 . 
 bucketByTime 
 ( 
 1 
 , 
  
 TimeUnit 
 . 
 DAYS 
 ) 
  
 . 
 setTimeRange 
 ( 
 startTime 
 . 
 toEpochSecond 
 (), 
  
 endTime 
 . 
 toEpochSecond 
 (), 
  
 TimeUnit 
 . 
 SECONDS 
 ) 
  
 . 
 build 
 () 
 Fitness 
 . 
 getHistoryClient 
 ( 
 this 
 , 
  
 GoogleSignIn 
 . 
 getAccountForExtension 
 ( 
 this 
 , 
  
 fitnessOptions 
 )) 
  
 . 
 readData 
 ( 
 request 
 ) 
  
 . 
 addOnSuccessListener 
  
 { 
  
 response 
  
 - 
>  
 val 
  
 totalSteps 
  
 = 
  
 response 
 . 
 buckets 
  
 . 
 flatMap 
  
 { 
  
 it 
 . 
 dataSets 
  
 } 
  
 . 
 flatMap 
  
 { 
  
 it 
 . 
 dataPoints 
  
 } 
  
 . 
 sumBy 
  
 { 
  
 it 
 . 
 getValue 
 ( 
 Field 
 . 
 FIELD_STEPS 
 ). 
 asInt 
 () 
  
 } 
  
 Log 
 . 
 i 
 ( 
 TAG 
 , 
  
 "Total steps: 
 $ 
 totalSteps 
 " 
 ) 
  
 }

REST

Your app can read the current daily step count total across all data sources by making a POST request and querying the com.google.step_count.delta data type for the specified time period.
