我正在使用 Google Fitness API 构建一个计步器应用程序。
我可以通过 HistoyAPI.readDailyTotal() 获取每日步数
private void getTodaySteps() {
PendingResult<DailyTotalResult> result = Fitness.HistoryApi.readDailyTotal(mClient, DataType.TYPE_STEP_COUNT_DELTA);
if (result != null) {
DailyTotalResult totalResult = result.await(30, TimeUnit.SECONDS);
if (totalResult.getStatus().isSuccess()) {
DataSet totalSet = totalResult.getTotal();
final long total = totalSet.isEmpty()
? 0
: totalSet.getDataPoints().get(0).getValue(Field.FIELD_STEPS).asInt();
runOnUiThread(new Runnable() {
@Override
public void run() {
Log.i(TAG, "Steps today: " + total);
tv_StepsToday.setText("" + total);
if (total >= (stepsToday + stepsNow)) {
stepsNow = 0;
stepsToday = total;
publishTodaysStepData();
}
}
});
} else {
// handle failure
Log.e(TAG, "Não foi possível obter o histórico de passos");
}
} else {
Log.e(TAG, "result nulo!");
}
}
我还使用 SensorAPI 来获取上次读取的增量步骤，然后我只需将两者相加并获得一个很好的响应式计步器。
private void subscribeSteps() {
Fitness.RecordingApi.subscribe(mClient, DataType.TYPE_STEP_COUNT_DELTA)
.setResultCallback(new ResultCallback<Status>() {
@Override
public void onResult(Status status) {
if (status.isSuccess()) {
if (status.getStatusCode()
== FitnessStatusCodes.SUCCESS_ALREADY_SUBSCRIBED) {
Log.i(TAG, "Existing subscription for activity detected.");
} else {
Log.i(TAG, "Successfully subscribed!");
}
} else {
Log.i(TAG, "There was a problem subscribing.");
}
}
});
}
private void unsubscribeStepsAndDeleteData() {
Fitness.RecordingApi.unsubscribe(mClient, DataType.TYPE_STEP_COUNT_DELTA)
.setResultCallback(new ResultCallback<Status>() {
@Override
public void onResult(Status status) {
if (status.isSuccess()) {
Log.i(TAG, "Successfully unsubscribed for data type: step count delta");
deleteData();
} else {
// Subscription not removed
Log.i(TAG, "Failed to unsubscribe for data type: step count delta");
}
}
});
}
private void getLiveSteps() {
if (!listenerRegistered) {
Log.v(TAG, "mandando requisição do sensor...");
SensorRequest req = new SensorRequest.Builder()
.setDataType(DataType.TYPE_STEP_COUNT_DELTA)
.setSamplingRate(1, TimeUnit.SECONDS)
.build();
OnDataPointListener listener = new OnDataPointListener() {
@Override
public void onDataPoint(final DataPoint dataPoint) {
Log.v(TAG, "new datapoint: " + dataPoint.toString());
for (final Field field : dataPoint.getDataType().getFields()) {
runOnUiThread(new Runnable() {
@Override
public void run() {
if (dataPoint.getTimestampNanos() != oldTimeStampNanos) {
oldTimeStampNanos = dataPoint.getTimestampNanos();
long result = (long) dataPoint.getValue(field).asInt();
Log.i(TAG, "steps now: " + result);
stepsNow += result;
publishTodaysStepData();
}
}
});
}
}
};
Fitness.SensorsApi.add(mClient, req, listener).setResultCallback(new ResultCallback<Status>() {
@Override
public void onResult(Status status) {
if (status.isSuccess()) {
Log.i(TAG, "Listener registered!");
listenerRegistered = true;
} else {
Log.i(TAG, "Listener not registered.");
}
}
});
}
}
但是我无法清除日常步骤。我正在尝试使用API 示例中的代码：
private void deleteData() {
Log.i(TAG, "Deleting today's step count data");
// [START delete_dataset]
// Set a start and end time for our data, using a start time of 1 day before this moment.
Calendar cal = Calendar.getInstance();
Date now = new Date();
cal.setTime(now);
long endTime = cal.getTimeInMillis();
cal.add(Calendar.DAY_OF_YEAR, -1);
long startTime = cal.getTimeInMillis();
// Create a delete request object, providing a data type and a time interval
DataDeleteRequest request = new DataDeleteRequest.Builder()
.setTimeInterval(startTime, endTime, TimeUnit.MILLISECONDS)
.addDataType(DataType.TYPE_STEP_COUNT_DELTA)
.build();
// Invoke the History API with the Google API client object and delete request, and then
// specify a callback that will check the result.
Fitness.HistoryApi.deleteData(mClient, request)
.setResultCallback(new ResultCallback<Status>() {
@Override
public void onResult(Status status) {
if (status.isSuccess()) {
Log.i(TAG, "Successfully deleted today's step count data");
} else {
// The deletion will fail if the requesting app tries to delete data
// that it did not insert.
Log.i(TAG, "Failed to delete today's step count data");
}
}
});
// [END delete_dataset]
}
这是一个错误，还是我只是做错了什么？
--编辑： 我的 GoogleApiClient 生成器
private void buildFitnessClient() {
// Create the Google API Client
mClient = new GoogleApiClient.Builder(this)
.addApi(Fitness.SENSORS_API)
.addApi(Fitness.HISTORY_API)
.addApi(Fitness.RECORDING_API)
.addScope(new Scope(Scopes.FITNESS_LOCATION_READ_WRITE))
.addScope(new Scope(Scopes.FITNESS_ACTIVITY_READ_WRITE))
.addConnectionCallbacks(
new GoogleApiClient.ConnectionCallbacks() {
@Override
public void onConnected(Bundle bundle) {
Log.i(TAG, "Connected!!!");
// Now you can make calls to the Fitness APIs.
// Put application specific code here.subscribeSteps();
refreashAll();
}
@Override
public void onConnectionSuspended(int i) {
// If your connection to the sensor gets lost at some point,
// you'll be able to determine the reason and react to it here.
if (i == GoogleApiClient.ConnectionCallbacks.CAUSE_NETWORK_LOST) {
Log.i(TAG, "Connection lost. Cause: Network Lost.");
} else if (i == GoogleApiClient.ConnectionCallbacks.CAUSE_SERVICE_DISCONNECTED) {
Log.i(TAG, "Connection lost. Reason: Service Disconnected");
}
}
}
)
.addOnConnectionFailedListener(
new GoogleApiClient.OnConnectionFailedListener() {
// Called whenever the API client fails to connect.
@Override
public void onConnectionFailed(ConnectionResult result) {
Log.i(TAG, "Connection failed. Cause: " + result.toString());
if (!result.hasResolution()) {
// Show the localized error dialog
GooglePlayServicesUtil.getErrorDialog(result.getErrorCode(),
LoginActivity.this, 0).show();
return;
}
// The failure has a resolution. Resolve it.
// Called typically when the app is not yet authorized, and an
// authorization dialog is displayed to the user.
if (!authInProgress) {
try {
Log.i(TAG, "Attempting to resolve failed connection");
authInProgress = true;
result.startResolutionForResult(LoginActivity.this,
REQUEST_OAUTH);
} catch (IntentSender.SendIntentException e) {
Log.e(TAG,
"Exception while starting resolution activity", e);
}
}
}
}
)
.build();
}
