我在一类 Pinger.java 中有以下代码

public class Pinger extends Service implements LocationListener, GoogleApiClient.ConnectionCallbacks,
        GoogleApiClient.OnConnectionFailedListener {    
    @Override
    public void onCreate() {
    // start the API for recognition
        mGoogleApiClient = new GoogleApiClient.Builder(this)
                .addApi(LocationServices.API)
                .addApi(ActivityRecognition.API)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .build();

        mGoogleApiClient.connect();
}
    // other code here

    @Override
    public void onConnected(Bundle bundle) {
        Intent acr_intent = new Intent(this, ActivityRecognitionService.class);
        PendingIntent pIntent = PendingIntent.getService(this, 0, acr_intent, PendingIntent.FLAG_UPDATE_CURRENT);
        Toast.makeText(this, "Connection!", Toast.LENGTH_SHORT).show();
        ActivityRecognition.ActivityRecognitionApi.requestActivityUpdates(mGoogleApiClient, 0, pIntent);
    }
}

我的 ActivityRecognitionService.java 看起来像这样： public class ActivityRecognitionService extends IntentService {

private String TAG = this.getClass().getSimpleName();

public ActivityRecognitionService() {
    super("My Activity Recognition Service");
}

@Override
protected void onHandleIntent(Intent intent) {
    if (ActivityRecognitionResult.hasResult(intent)) {
        ActivityRecognitionResult result = ActivityRecognitionResult.extractResult(intent);
        Log.i("AR", getType(result.getMostProbableActivity().getType()) + "t" + result.getMostProbableActivity().getConfidence());
        Intent i = new Intent("com.xyz.xyz.ACTIVITY_RECOGNITION_DATA");
        i.putExtra("Activity", getType(result.getMostProbableActivity().getType()));
        i.putExtra("Confidence", result.getMostProbableActivity().getConfidence());
        Toast.makeText(this, "Broadcast!", Toast.LENGTH_SHORT).show();
        sendBroadcast(i);
    }
}

private String getType(int type) {
    if (type == DetectedActivity.UNKNOWN)
        return "Unknown";
    else if (type == DetectedActivity.IN_VEHICLE)
        return "In Vehicle";
    else if (type == DetectedActivity.ON_BICYCLE)
        return "On Bicycle";
    else if (type == DetectedActivity.ON_FOOT)
        return "On Foot";
    else if (type == DetectedActivity.STILL)
        return "Still";
    else if (type == DetectedActivity.TILTING)
        return "Tilting";
    else
        return "";
}

在 ActivityRecognitionService.java 中，似乎“广播”的 Toast 没有出现，我试图理解为什么不查看日志文件也似乎 ActivityRecognitionService.java 没有被 Pinger.java 调用。请告知，我试图弄清楚一旦我能做到这一点，然后我想我可以从我设置的广播服务中读取活动。
