Question

我想使用Google Play服务提供的Activity Recognition API，但我这样做有问题。首先，我无法找到并更新适合我的指南，所以我做了一些类似于github上的“官方”示例的女巫正在我的手机上工作。

到目前为止，我所做的是：

1）在清单

中添加

<uses-permission android:name="com.google.android.gms.permission.ACTIVITY_RECOGNITION" />

2）添加了内部gradle（因为我在这个版本中使用了其他游戏服务，所以它是10.0.1）

compile 'com.google.android.gms:play-services-location:10.0.1'

3）我创建了一个新类

public class ActivityRecognizationIntentService extends IntentService {

public ActivityRecognizationIntentService() {
    super("ActivityRecognizationIntentService");
}

@Override
protected void onHandleIntent(Intent intent) {

    ActivityRecognitionResult result = ActivityRecognitionResult.extractResult(intent);
    Intent localIntent = new Intent(AddictionFour.BROADCAST_ACTION);

    // Get the list of the probable activities associated with the current state of the
    // device. Each activity is associated with a confidence level, which is an int between
    // 0 and 100.
    ArrayList<DetectedActivity> detectedActivities = (ArrayList) result.getProbableActivities();

    // Broadcast the list of detected activities.
    localIntent.putExtra(AddictionFour.ACTIVITY_EXTRA, detectedActivities);
    LocalBroadcastManager.getInstance(this).sendBroadcast(localIntent);
}}

4）在我想要使用API的GameActivity类中，我对此进行了更改（注意：我只发布相关的代码）

public void onCreate(Bundle savedInstanceState) {
    // connection to Google Play Games
    mGoogleApiClient = new GoogleApiClient.Builder(MainActivity.getContextOfApplication())
    .addConnectionCallbacks(this)
    .addOnConnectionFailedListener(this)
    .addApi(ActivityRecognition.API)
    .addApi(Games.API).addScope(Games.SCOPE_GAMES)
    // add other APIs and scopes here as needed
    .build();
    mGoogleApiClient.connect();
}

@Override
public void onConnected(Bundle arg0) {
    ActivityRecognition.ActivityRecognitionApi.requestActivityUpdates(mGoogleApiClient, 0, getActivityDetectionPendingIntent());
}

@Override
public void onResume() {
    LocalBroadcastManager.getInstance(this).registerReceiver(mBroadcastReceiver, new IntentFilter(AddictionFour.BROADCAST_ACTION));
    super.onResume();
}

private PendingIntent getActivityDetectionPendingIntent() {
    Intent intent = new Intent(this, ActivityRecognizationIntentService.class);

    // We use FLAG_UPDATE_CURRENT so that we get the same pending intent back when calling
    // requestActivityUpdates() and removeActivityUpdates().
    return PendingIntent.getService(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
}

public class ActivityDetectionBroadcastReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
    //not relevant code for now (read below)
    }

}

基本上我在做github上的例子正在做同样的事情，app没有任何错误并且不会崩溃但是onHandleIntent永远不会被调用。我错过了什么？

PS：除了onReceive of ActivityDetectionBroadcastReceiver之外，执行第4点内的所有代码。
