Every data point in Google Fit has an associated data source. Data sources
contain information that identifies the app or the device that collects or
transforms the data. The package name of the app is available for data sources
that don't represent a physical sensor.
Google Fit lets you do the following:
Invoke an intent to view data that's associated with a specific app.
To register your app to receive intents from other health and wellness apps,
declare an intent filter in your manifest that's similar to the following:
Each intent that your app receives from Google Fit is of only one type,
but you can filter for multiple MIME types in a single intent filter. Your app's
intent filter needs to include all of the data types that your app supports,
including custom data types.
The fitness intents include the following extras:
vnd.google.gms.fitness.start_time
vnd.google.gms.fitness.end_time
vnd.google.gms.fitness.data_source
You can obtain data from these extras as follows:
Kotlin
overridefunonCreate(savedInstanceState:Bundle?){super.onCreate(savedInstanceState)...valsupportedType=DataType.getMimeType(DataType.TYPE_STEP_COUNT_DELTA)if(Intent.ACTION_VIEW==intent.action&&supportedType==intent.type){// Get the intent extrasvalstartTime=Fitness.getStartTime(intent,TimeUnit.MILLISECONDS);valendTime=Fitness.getEndTime(intent,TimeUnit.MILLISECONDS)valdataSource=DataSource.extract(intent)}}
Java
@OverridepublicvoidonCreate(@NullableBundlesavedInstanceState){super.onCreate(savedInstanceState);...StringsupportedType=DataType.getMimeType(DataType.TYPE_STEP_COUNT_DELTA);if(Intent.ACTION_VIEW.equals(getIntent().getAction())&&supportedType.equals(getIntent().getType()){// Get the intent extraslongstartTime=Fitness.getStartTime(getIntent(),TimeUnit.MILLISECONDS);longendTime=Fitness.getEndTime(getIntent(),TimeUnit.MILLISECONDS);DataSourcedataSource=DataSource.extract(getIntent());}}
To obtain the MIME type for a custom data type, use theMIME_TYPE_PREFIXconstant:
// Inside your activityvalstartTime=...valendTime=...valdataSource=...valdataType=...valfitIntent=HistoryApi.ViewIntentBuilder(this,dataType).setTimeInterval(startTime,endTime,TimeUnit.MILLISECONDS).setDataSource(dataSource)// Optional if a specific data source is desired.setPreferredApplication("com.example.app")// Optional if you'd like a// specific app to handle the intent if that app is installed on the device.build()
Java
// Inside your activitylongstartTime=...longendTime=...DataSourcedataSource=...DataTypedataType=...IntentfitIntent=newHistoryApi.ViewIntentBuilder(this,dataType).setTimeInterval(startTime,endTime,TimeUnit.MILLISECONDS).setDataSource(dataSource)// Optional if a specific data source is desired.setPreferredApplication("com.example.app")// Optional if you'd like a// specific app to handle the intent if that app is installed on the device.build();

Data sources\ncontain information that identifies the app or the device that collects or\ntransforms the data. The package name of the app is available for data sources\nthat don't represent a physical sensor.\n\nGoogle Fit lets you do the following:\n\n- Invoke an intent to view data that's associated with a specific app.\n- Receive intents to show data using your app.\n- Find out which app inserted a [session](/fit/sessions). For more information, see [Work with sessions](/fit/android/using-sessions).\n\nDetermine which app inserted a data point\n-----------------------------------------\n\nTo obtain the package name of the application that inserted a data point, first\ncall [`DataPoint.getOriginalDataSource`](/android/reference/com/google/android/gms/fitness/data/DataPoint#public-datasource-getoriginaldatasource)\nto get the data source, then call the\n[`DataSource.getAppPackageName`](/android/reference/com/google/android/gms/fitness/data/DataSource#public-string-getapppackagename)\nmethod: \n\n### Kotlin\n\n```kotlin\nval dataPoint : DataPoint = ...\nval dataSource = dataPoint.originalDataSource\nval appPkgName = dataSource.appPackageName\n```\n\n### Java\n\n```java\nDataPoint dataPoint = ...\nDataSource dataSource = dataPoint.getOriginalDataSource();\nString appPkgName = dataSource.getAppPackageName();\n```\n\nReceive intents from other apps\n-------------------------------\n\nTo register your app to receive intents from other health and wellness apps,\ndeclare an intent filter in your manifest that's similar to the following: \n\n```xml\n\u003cintent-filter\u003e\n \u003caction android:name=\"vnd.google.fitness.VIEW\" /\u003e\n \u003cdata android:mimeType=\"vnd.google.fitness.data_type/com.google.step_count.cumulative\" /\u003e\n \u003cdata android:mimeType=\"vnd.google.fitness.data_type/com.google.step_count.delta\" /\u003e\n\u003c/intent-filter\u003e\n```\n| **Note:** Don't include the `DEFAULT` category in your intent filter, unless you want your app to receive intents for data created by other apps.\n\nEach intent that your app receives from Google Fit is of only one type,\nbut you can filter for multiple MIME types in a single intent filter. Your app's\nintent filter needs to include all of the data types that your app supports,\nincluding custom data types.\n\nThe fitness intents include the following extras:\n\n- `vnd.google.gms.fitness.start_time`\n- `vnd.google.gms.fitness.end_time`\n- `vnd.google.gms.fitness.data_source`\n\nYou can obtain data from these extras as follows: \n\n### Kotlin\n\n```kotlin\noverride fun onCreate(savedInstanceState: Bundle?) {\n super.onCreate(savedInstanceState)\n ...\n val supportedType = DataType.getMimeType(DataType.TYPE_STEP_COUNT_DELTA)\n\n if (Intent.ACTION_VIEW == intent.action && supportedType == intent.type) {\n // Get the intent extras\n val startTime = Fitness.getStartTime(intent, TimeUnit.MILLISECONDS);\n val endTime = Fitness.getEndTime(intent, TimeUnit.MILLISECONDS)\n val dataSource = DataSource.extract(intent)\n }\n}\n```\n\n### Java\n\n```java\n@Override\npublic void onCreate(@Nullable Bundle savedInstanceState) {\n super.onCreate(savedInstanceState);\n ...\n String supportedType = DataType.getMimeType(DataType.TYPE_STEP_COUNT_DELTA);\n\n if (Intent.ACTION_VIEW.equals(getIntent().getAction()) && supportedType.equals(getIntent().getType())\n {\n // Get the intent extras\n long startTime = Fitness.getStartTime(getIntent(), TimeUnit.MILLISECONDS);\n long endTime = Fitness.getEndTime(getIntent(), TimeUnit.MILLISECONDS);\n DataSource dataSource = DataSource.extract(getIntent());\n }\n}\n```\n\nTo obtain the MIME type for a custom data type, use the\n[`MIME_TYPE_PREFIX`](/android/reference/com/google/android/gms/fitness/data/DataType#public-static-final-string-mime_type_prefix)\nconstant: \n\n### Kotlin\n\n```kotlin\nval supportedType = DataType.MIME_TYPE_PREFIX + \"com.company.customdatatype\"\n```\n\n### Java\n\n```java\nString supportedType = DataType.MIME_TYPE_PREFIX + \"com.company.customdatatype\";\n```\n\nInvoke an intent to view data\n-----------------------------\n\nTo invoke an intent to view data with another app, use the\n[`HistoryApi.ViewIntentBuilder`](/android/reference/com/google/android/gms/fitness/HistoryApi.ViewIntentBuilder)\nclass: \n\n### Kotlin\n\n```kotlin\n// Inside your activity\nval startTime = ...\nval endTime = ...\nval dataSource = ...\nval dataType = ...\n\nval fitIntent = HistoryApi.ViewIntentBuilder(this, dataType)\n .setTimeInterval(startTime, endTime, TimeUnit.MILLISECONDS)\n .setDataSource(dataSource) // Optional if a specific data source is desired\n .setPreferredApplication(\"com.example.app\") // Optional if you'd like a\n // specific app to handle the intent if that app is installed on the device\n .build()\n```\n\n### Java\n\n```java\n// Inside your activity\nlong startTime = ...\nlong endTime = ...\nDataSource dataSource = ...\nDataType dataType = ...\n\nIntent fitIntent = new HistoryApi.ViewIntentBuilder(this, dataType)\n .setTimeInterval(startTime, endTime, TimeUnit.MILLISECONDS)\n .setDataSource(dataSource) // Optional if a specific data source is desired\n .setPreferredApplication(\"com.example.app\") // Optional if you'd like a\n // specific app to handle the intent if that app is installed on the device\n .build();\n```\n\nLearn more about how to use [intents and intent\nfilters](https://developer.android.com/guide/components/intents-filters)."]]
