Android地理围栏-没有出现意图？

Question

我有一个奇怪的问题。

我使用Google服务实现了地理围栏。(下面是实现)

在我的设备上(Samsung Galaxy S和Moto X)它们运行得很好。但是在其他一些设备(HTC Incredible S，Galaxy Note)上，我收不到转换意图。从来没有。即使在围栏中心有着非常准确的GPS定位也是如此。日志中没有任何可疑的内容。没有错误，没有警告。没有意图，服务也不会启动。

有人见过这样的事情吗？(这很奇怪，因为我看不出能够区分它们工作和不工作的设备之间的任何联系。不是制造商，也不是Android版本，所有设备上的Play服务都是最新的。)

实现:

更新地理围栏：

 public class UpdateGeofences extends BroadcastReceiver implements
        GooglePlayServicesClient.ConnectionCallbacks,
        GooglePlayServicesClient.OnConnectionFailedListener,
        LocationClient.OnAddGeofencesResultListener,
        DataUpdateCallback {

    private LocationClient mLocationClient;
    private Context ctx;

    @Override
    public void onReceive(Context context, Intent intent) {
        Log.d("NOTICE", "Updating Geofences");
        ctx = context;
        mLocationClient = new LocationClient(context, this, this);
        mLocationClient.connect();
    }

    @Override
    public void onConnected(Bundle bundle) {
        GeofenceProvider geofenceProvider = new GeofenceProvider(ctx);
        geofenceProvider.open();

        //reactivate geofences
        List<Geofence> geofences = geofenceProvider.getActiveGeofences(mLocationClient.getLastLocation());
        Intent intent = new Intent(ctx, ShowNotificationService.class);
        PendingIntent pendingIntent = PendingIntent.getService(ctx, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
        if (geofences.size() > 0) mLocationClient.addGeofences(geofences, pendingIntent, this);
        else mLocationClient.disconnect();
    }

    @Override
    public void onAddGeofencesResult(int i, String[] strings) {
        // If adding the geofences was successful
        if (LocationStatusCodes.SUCCESS != i) {
            Log.e("Geofences", "Error adding geofences: "+ Arrays.toString(strings)+ " Code: "+i);
        }
        mLocationClient.disconnect();
    }    
}

显示通知服务:

    public class ShowNotificationService extends IntentService {

    public ShowNotificationService() {
        super("ReceiveTransitionsIntentService");
    }

    @Override
    protected void onHandleIntent(Intent intent) {
        Log.d("NOTICE", "Android geofence notification!");
        if (LocationClient.hasError(intent)) {
            int errorCode = LocationClient.getErrorCode(intent);
            Log.e("ReceiveTransitionsIntentService", "Location Services error: " + Integer.toString(errorCode));
            Crashlytics.logException(new RuntimeException("Location Services error: "+errorCode));
        } else {
            int transitionType = LocationClient.getGeofenceTransition(intent);
            if (transitionType == Geofence.GEOFENCE_TRANSITION_ENTER) { //ak vstupujem pozriem sa ci uz sa mi to nevyhodilo dnes
                List<Geofence> triggerList = LocationClient.getTriggeringGeofences(intent);
                Log.d("NOTICE", "Transition Enter");
                GeofenceProvider mProvider = new GeofenceProvider(this);
                mProvider.open();
                try {

                        }
                    }
                } catch (Exception e) {
                    Crashlytics.logException(e);
                    e.printStackTrace();
                } finally {
                    mProvider.close();
                }

            } else if(transitionType == Geofence.GEOFENCE_TRANSITION_EXIT) {    //ak odchadzam, oznacim to patricne v db

                Log.e("ReceiveTransitionsIntentService", "Geofence transition error: " + Integer.toString(transitionType));
                Crashlytics.logException(new RuntimeException("Invalid geofence transition"));
            }
        }
    }
}

在 UpdateGeofences 中，我省略了连接到 PlayServices 所需的方法，因为它们基本上是从演示应用程序复制的，而且我在其他地方成功使用它们...

主活动并不重要，它只是在每次启动时发送广播以启动 UpdateGeofences。

GeofenceProvider 也不是问题，我在其他地方使用相同的代码没有问题。

最终，我通过在ShowNotificationService中设置exported="true"来解决了这个问题。

就像这样：

<service android:name="test.package.services.geofences.ShowNotificationService"
        android:label="@string/app_name"
        android:exported="true"/>

似乎意图被错误的进程触发，导致安全错误。不确定为什么会发生这种情况...

你能告诉我在开发者网站提供的演示中，我需要在geofence2中放置什么经纬度和半径吗？ - Amit Jayaswal

我不明白 android:exported="true" 怎么可能有任何影响！ - IgorGanapolsky
