为什么我的结果不显示

Question

我的代码未显示活动识别服务的结果。 我该如何解决我的问题？

这是我的代码ActivityRecognizeService.java

package com.kobe.internship.realtimeactivity;

import android.app.IntentService;
import android.content.Intent;
import android.support.annotation.Nullable;
import android.util.Log;

import com.google.android.gms.location.ActivityRecognitionResult;
import com.google.android.gms.location.DetectedActivity;

import java.util.List;

public class ActivityRecognizedService extends IntentService {

    private static final String TAG = "ActivityRecognizedServi";
    public ActivityRecognizedService(){
        super("ActivityRecognizedService");
    }

    public ActivityRecognizedService(String name){
        super(name);
    }

    @Override
    protected void onHandleIntent(@Nullable Intent intent) {
        if(ActivityRecognitionResult.hasResult(intent)){
            ActivityRecognitionResult result = ActivityRecognitionResult.extractResult(intent);
            handleDetectedActivity(result.getProbableActivities());
        }
    }

    private void handleDetectedActivity(List<DetectedActivity> probableActivities){

        for (DetectedActivity activity: probableActivities) {
            switch (activity.getType()) {
                case DetectedActivity.IN_VEHICLE: {
                    Log.d(TAG, "handleDetectedActivity: IN_VEHICLE: " +activity.getConfidence());
                    break;
                }
                case DetectedActivity.ON_BICYCLE: {
                    Log.d(TAG, "handleDetectedActivity: ON_BYCYCLE: " + activity.getConfidence());
                    break;
                }
                case DetectedActivity.ON_FOOT: {
                    Log.d(TAG, "handleDetectedActivity: ON_FOOT: " + activity.getConfidence());
                    break;
                }
                case DetectedActivity.RUNNING: {
                    Log.d(TAG, "handleDetectedActivity: RUNNING: " + activity.getConfidence());
                    break;
                }
                case DetectedActivity.STILL: {
                    Log.d(TAG, "handleDetectedActivity: STILL: "+ activity.getConfidence());
                    break;
                }
                case DetectedActivity.WALKING: {
                    Log.d(TAG, "handleDetectedActivity: WALKING: " + activity.getConfidence());
                    break;
                }
                case DetectedActivity.TILTING: {
                    Log.d(TAG, "handleDetectedActivity: TILING: " + activity.getConfidence());
                    break;
                }
                case DetectedActivity.UNKNOWN: {
                    Log.d(TAG, "handleDetectedActivity: UNKNOWN: " + activity.getConfidence());
                    break;
                }

            }
        }
    }
}

这是我的MainActivity.java

package com.kobe.internship.realtimeactivity;

import android.app.PendingIntent;
import android.content.Intent;
import android.support.annotation.NonNull;
import android.support.annotation.Nullable;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.api.GoogleApiClient;
import com.google.android.gms.location.ActivityRecognition;

public class MainActivity extends AppCompatActivity implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener{

    public  GoogleApiClient mApiClient;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mApiClient = new GoogleApiClient.Builder(MainActivity.this)
                .addApi(ActivityRecognition.API)
                .addConnectionCallbacks(MainActivity.this)
                .addOnConnectionFailedListener(MainActivity.this)
                .build();
    }

    @Override
    public void onConnected(@Nullable Bundle bundle) {
        Intent intent = new Intent(MainActivity.this, ActivityRecognizedService.class);
        PendingIntent pendingIntent = PendingIntent.getService(MainActivity.this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
        ActivityRecognition.ActivityRecognitionApi.requestActivityUpdates(mApiClient, 2000, pendingIntent);

    }

    @Override
    public void onConnectionSuspended(int i) {

    }

    @Override
    public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {

    }
}
