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，它们运行完美。在其他一些设备(HTC Incredible S、Galaxy Note)上，我没有收到任何转换 Intent 。绝不。凭借出色、准确的 GPS 定位，站在栅栏中间。没有什么。日志中没有任何可疑之处。没有错误，没有警告。没有 itents 来，服务没有启动。

有没有人见过这样的东西？ (这很奇怪，因为我看不到可以工作的设备和不能工作的设备之间有任何联系。它不是制造商，不是 Android 版本，Play 服务在所有这些设备上都是最新的。)

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));

                List<Geofence> triggerList = LocationClient.getTriggeringGeofences(intent);
                Log.d("NOTICE", "Transition Enter");
                GeofenceProvider mProvider = new GeofenceProvider(this);

                    }
                } 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

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，我在其他地方成功地使用了它们...

Main Activity 是无关紧要的，它只是在每次启动时发送广播来启动 UpdateGeofences。

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

最佳答案

最终，我通过在 ShowNofiticationService 中设置 exported="true"设法解决了这个问题。

像这样:

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

似乎 Intent 是由 ID 错误的进程触发的，这导致了安全错误。不确定为什么会发生这种情况......

关于Android Geofencing - 没有 future 的 Intent ？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/21090674/
