记录健身数据

通过 Recording API，您的应用可以请求在 从而节省电池电量关联了一项订阅 包含健身数据类型或特定数据 来源。

您可以为不同的数据类型或数据源创建多个订阅 。Google 健身会存储来自有效订阅、 即使您的应用未运行，也可以恢复这些订阅， 系统重启。

所记录的数据会在用户的健身记录中提供。如果您还希望 在应用中实时显示数据，请使用 传感器 API 与 Recording API 结合使用。录制 包含课程元数据的健身数据，请使用 Session API。

订阅健身数据

要请求在您的应用中收集传感器数据，请使用 RecordingClient.subscribe 方法，如以下代码段所示：

Kotlin

Fitness.getRecordingClient(this, GoogleSignIn.getAccountForExtension(this, fitnessOptions))
    // This example shows subscribing to a DataType, across all possible data
    // sources. Alternatively, a specific DataSource can be used.
    .subscribe(DataType.TYPE_STEP_COUNT_DELTA)
    .addOnSuccessListener {
        Log.i(TAG, "Successfully subscribed!")
    }
    .addOnFailureListener { e ->
        Log.w(TAG, "There was a problem subscribing.", e)
    }

Java

Fitness.getRecordingClient(this, GoogleSignIn.getAccountForExtension(this, fitnessOptions))
        // This example shows subscribing to a DataType, across all possible
        // data sources. Alternatively, a specific DataSource can be used.
        .subscribe(DataType.TYPE_STEP_COUNT_DELTA)
        .addOnSuccessListener(unused ->
                Log.i(TAG, "Successfully subscribed!"))
        .addOnFailureListener( e ->
        Log.w(TAG, "There was a problem subscribing.", e));

如果订阅添加成功，Google 健身会存储健身数据 类型的数据 TYPE_STEP_COUNT_DELTA 会代表您的应用显示在健身历史记录中。此订阅显示在 您的应用的有效订阅的列表。

如需在您的应用中订阅更多类型的健身数据，请按照 但每次都提供不同的健身数据类型。

列出有效订阅

要获取您应用程序的有效订阅的列表，请使用 RecordingClient.listSubscriptions 方法，如以下代码段所示：

Kotlin

Fitness.getRecordingClient(this, GoogleSignIn.getAccountForExtension(this, fitnessOptions))
    .listSubscriptions()
    .addOnSuccessListener { subscriptions ->
        for (sc in subscriptions) {
            val dt = sc.dataType
            Log.i(TAG, "Active subscription for data type: ${dt.name}")
        }
    }

Java

Fitness.getRecordingClient(this, GoogleSignIn.getAccountForExtension(this, fitnessOptions))
        .listSubscriptions()
        .addOnSuccessListener(subscriptions -> {
            for (Subscription sc : subscriptions) {
                DataType dt = sc.getDataType();
                Log.i(TAG, "Active subscription for data type: ${dt.name}");
            }
    });
}

退订健身数据

如需停止在您的应用中收集传感器数据，请使用 RecordingClient.unsubscribe 方法，如以下代码段所示：

Kotlin

Fitness.getRecordingClient(this, GoogleSignIn.getAccountForExtension(this, fitnessOptions))
    // This example shows unsubscribing from a DataType. A DataSource should
    // be used where the subscription was to a DataSource. Alternatively, if
    // the client doesn't maintain its subscription information, they can use
    // an element from the return value of listSubscriptions(), which is of
    // type Subscription.
    .unsubscribe(DataType.TYPE_STEP_COUNT_DELTA)
    .addOnSuccessListener {
        Log.i(TAG,"Successfully unsubscribed.")
    }
    .addOnFailureListener { e->
        Log.w(TAG, "Failed to unsubscribe.")
        // Retry the unsubscribe request.
    }

Java

Fitness.getRecordingClient(this, GoogleSignIn.getAccountForExtension(this, fitnessOptions))
        // This example shows unsubscribing from a DataType. A DataSource
        // should be used where the subscription was to a DataSource.
        // Alternatively, if the client doesn’t maintain its subscription
        // information, they can use an element from the return value of
        // listSubscriptions(), which is of type Subscription.
        .unsubscribe(DataType.TYPE_STEP_COUNT_DELTA)
        .addOnSuccessListener(unused ->
            Log.i(TAG,"Successfully unsubscribed."))
        .addOnFailureListener(e -> {
            Log.w(TAG, "Failed to unsubscribe.");
            // Retry the unsubscribe request.
        });
