No Data Sources show in Google Fit - wear-os

Question

I am trying to record location and speed from the Sensors API in Google Fit in my Watch Face Service (Android Wear). Here's the code I use:
private void connectFitnessDataListeners() {
Fitness.SensorsApi.findDataSources(mGoogleApiClient,
new DataSourcesRequest.Builder()
.setDataTypes(DataType.TYPE_ACTIVITY_SAMPLE)
.setDataTypes(DataType.TYPE_LOCATION_SAMPLE)
.setDataTypes(DataType.TYPE_SPEED)
// Can specify whether data type is raw or derived.
.setDataSourceTypes(DataSource.TYPE_RAW)
.build())
.setResultCallback(new ResultCallback<DataSourcesResult>() {
#Override
public void onResult(DataSourcesResult dataSourcesResult) {
Log.i(TAG, "Find Data Sources: " + dataSourcesResult.getStatus().toString());
for (DataSource dataSource : dataSourcesResult.getDataSources()) {
//only include dataSources from the watch
Log.i(TAG, "Data source found: " + dataSource.toString());
Log.i(TAG, String.format("Data Source device %s and type: %s", dataSource.getDevice().toString(),dataSource.getDataType().getName()));
if (dataSource.getDevice() != Device.getLocalDevice(getBaseContext())) continue;
//FIXME: Turn this into a loop over an array
if (dataSource.getDataType().equals(DataType.TYPE_ACTIVITY_SAMPLE) && (mActivitySampleListener == null)) {
Log.i(TAG, "Data source for ACTIVITY_SAMPLE found! Registering.");
mActivitySampleListener = registerFitnessDataListener(dataSource, DataType.TYPE_ACTIVITY_SAMPLE);
} else if (dataSource.getDataType().equals(DataType.TYPE_LOCATION_SAMPLE) && (mLocationSampleListener == null)) {
Log.i(TAG, "Data source for LOCATION_SAMPLE found! Registering.");
mLocationSampleListener = registerFitnessDataListener(dataSource, DataType.TYPE_ACTIVITY_SAMPLE);
} else if (dataSource.getDataType().equals(DataType.TYPE_SPEED) && (mSpeedListener == null)) {
Log.i(TAG, "Data source for SPEED found! Registering.");
mSpeedListener = registerFitnessDataListener(dataSource, DataType.TYPE_SPEED);
}
}
}
}
);
}
However, when I run this in an otherwise working onConnected call, I get no DataSources in the for loop (the Find Data Sources log call shows success).
Any thoughts as to what I should pursue?
UPDATE:
If I remove the setDataSourceTypes restriction, I get only this:
Data source found: DataSource{derived:Application{com.google.android.gms::null}:Device{Sony:SmartWatch 3:15e991d4::3:2}::DataType{com.google.speed[speed(f)]}}
Data Source device Device{Sony:SmartWatch 3:15e991d4::3:2} and type: com.google.speed
So why don't I see location information from the GPS?

This was my developer error: setDataTypes takes a vararg set of DataTypes; in my example I was only setting DataType for TYPE_SPEED
