【问题描述】:
我正在尝试通过我的表盘服务 (Android Wear) 中的 Google Fit 中的传感器 API 记录位置和速度。这是我使用的代码:
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);
}
}
}
}
);
}
但是,当我在一个正常工作的 onConnected 调用中运行它时,我在 for 循环中没有得到任何数据源(Find Data Sources 日志调用显示成功)。
关于我应该追求什么有什么想法吗?
更新:
如果我删除 setDataSourceTypes 限制,我只会得到这个:
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
那么为什么我看不到 GPS 的位置信息?
