Google Api客户端：未连接。调用Connect或等待onConnected（）被调用

Question

我实际上是尝试从后台服务中获取Google适合的步骤。让我们调用我的服务FitService.java。

@Override
public void onCreate() {
    super.onCreate();

    if(mFitnessClient == null){
        buildFitnessClient();
        Log.d(TAG, "FitnessClient created");
    }
}

@Override
protected void onHandleIntent(Intent intent) {
    Log.i(TAG, "onHandleIntent");
    //block until google fit connects.  Give up after 10 seconds.
    if (!mFitnessClient.isConnected() && !mFitnessClient.isConnecting()) {
        mTryingToConnect = true;
        mGoogleApiFitnessClient.connect();

        //Wait until the service either connects or fails to connect
        while (mTryingToConnect) {
            try {
                Thread.sleep(100, 0);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }

    if (mFitnessClient.isConnected()) {
        getSteps();
        Log.i(TAG, "google api client connected. ");
    } else {
        //Not connected
        Log.e(TAG, "Fit wasn't able to connect, so the request failed.");
    }
}

private void buildFitnessClient() {
    // Create the Google API Client
    mGoogleApiFitnessClient = new GoogleApiClient.Builder(this)
            .addApi(Fitness.HISTORY_API)
            .addScope(new Scope(Scopes.FITNESS_ACTIVITY_READ_WRITE))
            .addScope(new Scope(Scopes.FITNESS_BODY_READ_WRITE))
            .addScope(new Scope(Scopes.FITNESS_LOCATION_READ_WRITE))
            .addConnectionCallbacks(
                    new GoogleApiClient.ConnectionCallbacks() {

                        @Override
                        public void onConnected(Bundle bundle) {
                            Log.i(TAG, "Google Fit connected.");
                            mTryingToConnect = false;
                        }

                        @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.
                            mTryingToConnect = false;
                            if (i == GoogleApiClient.ConnectionCallbacks.CAUSE_NETWORK_LOST) {
                                Log.i(TAG, "Google Fit Connection lost.  Cause: Network Lost.");
                            } else if (i == GoogleApiClient.ConnectionCallbacks.CAUSE_SERVICE_DISCONNECTED) {
                                Log.i(TAG, "Google Fit Connection lost.  Reason: Service Disconnected");
                            }
                        }
                    }
            )
            .addOnConnectionFailedListener(
                    new GoogleApiClient.OnConnectionFailedListener() {
                        // Called whenever the API client fails to connect.
                        @Override
                        public void onConnectionFailed(ConnectionResult result) {
                            mTryingToConnect = false;
                        }
                    }
            )
            .build();
}

public void getStepsToday(){
    long total = 0;

    PendingResult<DailyTotalResult> result = Fitness.HistoryApi.readDailyTotal(mGoogleApiFitnessClient, DataType.TYPE_STEP_COUNT_DELTA);
    DailyTotalResult totalResult = result.await(30, TimeUnit.SECONDS);
    if (totalResult.getStatus().isSuccess()) {
        DataSet totalSet = totalResult.getTotal();
        total = totalSet.isEmpty()
                ? 0
                : totalSet.getDataPoints().get(0).getValue(Field.FIELD_STEPS).asInt();
            Log.i(TAG, "Total steps are the same: " + total);
    } else {
        Log.e(TAG, "There was a problem while getting the step count.");
    }
}

适用于大多数手机设备。但在其他一些设备上，我收到一个奇怪的错误：

有任何线索吗？
