我正在尝试编写一个简单的应用程序，该应用程序可从Android上的GoogleFit中提取数据，但是即使我在Google Fit上手动添加了数据，我返回的数据集也没有任何数据点。 。我的代码如下，可以在下面找到。我正在Android模拟器上运行此程序，但给我的印象是我应该仍然能够提取数据，因为我在.enableServerQueries()中使用了DataReadRequest.Builder。
MainActivity：
public void accessGoogleFit(GoogleSignInAccount account) {
Fitness.getRecordingClient(this, account)
.subscribe(DataType.TYPE_ACTIVITY_SAMPLES);
Calendar cal = Calendar.getInstance();
cal.setTime(new Date());
long endTime = cal.getTimeInMillis();
cal.add(Calendar.YEAR, -1);
long startTime = cal.getTimeInMillis();
GoogleApiClient client = new GoogleApiClient.Builder(this)
.addApi(Fitness.HISTORY_API)
.addScope(Fitness.SCOPE_ACTIVITY_READ)
.build();
client.connect();
DataReadRequest readRequest = new DataReadRequest.Builder()
.read(DataType.TYPE_STEP_COUNT_DELTA)
.read(DataType.AGGREGATE_ACTIVITY_SUMMARY)
.enableServerQueries()
.setTimeRange(startTime, endTime, TimeUnit.MILLISECONDS)
.build();
Fitness.getHistoryClient(this, GoogleSignIn.getLastSignedInAccount(this))
.readData(readRequest)
.addOnCompleteListener(new OnCompleteListener<DataReadResponse>() {
@Override
public void onComplete(@NonNull Task<DataReadResponse> task) {
System.out.println("Successful: " + task.isSuccessful());
if (task.isSuccessful()) {
List<DataSet> dataSets = task.getResult().getDataSets();
System.out.println("Size: " + dataSets.size());
for (DataSet set : dataSets) {
dumpDataSet(set);
}
}
}
});
}
private static void dumpDataSet(DataSet dataSet) {
Log.i("GoogleFitData", "Data returned for Data type: " + dataSet.getDataType().getName());
DateFormat dateFormat = getTimeInstance();
for (DataPoint dp : dataSet.getDataPoints()) {
Log.i("GoogleFitData", "Data point:");
Log.i("GoogleFitData", "\tType: " + dp.getDataType().getName());
Log.i("GoogleFitData", "\tStart: " + dateFormat.format(dp.getStartTime(TimeUnit.MILLISECONDS)));
Log.i("GoogleFitData", "\tEnd: " + dateFormat.format(dp.getEndTime(TimeUnit.MILLISECONDS)));
for (Field field : dp.getDataType().getFields()) {
Log.i("GoogleFitData", "\tField: " + field.getName() + " Value: " + dp.getValue(field));
}
}
}
我在logcat中注意到，存在与找不到我的设备密钥文件有关的错误，但是我真的不知道如何解决此问题。我不确定这是否相关，因为GoogleFit请求成功返回，只是没有任何数据。我已经在Google Cloud Console中启用了GoogleFit API，并放入了我的应用指纹证书和软件包。
