【问题描述】：

我有一个奇怪的问题。

我使用 Google 服务实现了地理围栏。 （下面的实现） 在我的设备（三星 Galaxy S 和 Moto X）上，它们运行良好。在其他一些设备（HTC Incredible S、Galaxy Note）上，我没有收到任何转换意图。绝不。凭借出色、准确的 GPS 定位，站在围栏中间。没有。日志中没有任何可疑之处。没有错误，没有警告。没有对象来，服务没有启动。

有没有人见过这样的事情？ （这很奇怪，因为我看不到可以工作的设备和不工作的设备之间有任何联系。它不是制造商，也不是 android 版本，所有这些设备上的 Play 服务都是最新的。）

实施：

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 
                    for (Geofence geofence : triggerList) 
                        String id = geofence.getRequestId();
                        String[] data = id.split(MyGeofence.delimiter);
                        Log.d("NOTICE", "Show notification: "+id);
                        if (data.length != 3) 
                            Crashlytics.logException(new RuntimeException("Invalid geofence id: " + id + "Data: "+ Arrays.toString(data)));
                            continue;
                        
                        if (mProvider.updateLastFire(Integer.valueOf(data[2]))) 
                            NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
                            builder.setContentTitle(data[0]);
                            builder.setContentText(data[1]);
                            builder.setSmallIcon(R.drawable.noticon);
                            Intent result = new Intent(this, CompassActivity.class);
                            PendingIntent pendingResult = PendingIntent.getActivity(this, 0, result, PendingIntent.FLAG_UPDATE_CURRENT);

                            mNotificationManager.notify(notID, not);
                        
                    
                 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
                List<Geofence> triggerList = LocationClient.getTriggeringGeofences(intent);
                Log.d("NOTICE", "Transition leave");
                GeofenceProvider mProvider = new GeofenceProvider(this);
                mProvider.open();
                try 
                    for (Geofence geofence : triggerList) 
                        String id = geofence.getRequestId();
                        String[] data = id.split(MyGeofence.delimiter);
                        if (data.length != 3) 
                            Crashlytics.logException(new RuntimeException("Invalid geofence id: " + id + "Data: "+ Arrays.toString(data)));
                            continue;
                        
                        mProvider.invalidateLastFire(Integer.valueOf(data[2]));
                        Log.d("NOTICE", "Invalidate last fire: "+id);
                    
                 catch (Exception e) 
                    Crashlytics.logException(e);
                    e.printStackTrace();
                 finally 
                    mProvider.close();
                

             else     // An invalid transition was reported
                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中复制的，并且我在其他地方成功使用它们...

主要活动无关紧要，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。

【参考方案1】：

最终，我设法通过在 ShowNofiticationService 中设置exported="true" 来解决这个问题。

像这样：

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

似乎意图是由具有错误 ID 的进程触发的，这导致了安全错误。不过不知道为什么会这样……

【讨论】：

你能告诉我我需要在 geofence2 中放置多少纬度和半径，在开发者网站上提供的演示中。 ?

我看不出 android:exported="true" 有什么不同！
