Android 地理围栏在 OnePlus、小米等手机中不触发

Android Geofencing Not Triggering in some mobile like OnePlus, Xiaomi etc

我正在根据 Android 文档的指南使用地理围栏代码。在索尼 XA1、三星 J7 Nxt、小米 5A、Poco f1、OnePlus 6 等真实设备上进行测试。地理围栏 EnterExit 正在运行妥妥的索尼XA1,三星J7 Nxt。

小米 & OnePlus 手机中的问题。

  1. 在小米5A 有时进入正常但退出不触发
  2. 在小米Poco f1中进入退出都不起作用
  3. 在 OnePlus Mobile 中,仅当应用程序打开时才有效。

地理围栏代码:

private GeofencingClient mGeofencingClient;
private ArrayList<Geofence> mGeofenceList;
private PendingIntent mGeofencePendingIntent;

mGeofenceList = new ArrayList<>();
mGeofencingClient = LocationServices.getGeofencingClient(getApplicationContext());

//Latitude & Longitude Comes from Array to Add
mGeofenceList.add(new Geofence.Builder().setRequestId(String.valueOf(mall.mallId)).setCircularRegion(
              mall.latitude,
              mall.longitude,
              mall.geofencingMeters)
             .setExpirationDuration(Geofence.NEVER_EXPIRE)
             .setTransitionTypes(Geofence.GEOFENCE_TRANSITION_ENTER | Geofence.GEOFENCE_TRANSITION_EXIT)
             .build());

private GeofencingRequest getGeofencingRequest() {

    GeofencingRequest.Builder builder = new GeofencingRequest.Builder();
    builder.setInitialTrigger(GeofencingRequest.INITIAL_TRIGGER_ENTER);
    builder.addGeofences(mGeofenceList);

    return builder.build();
}

private PendingIntent getGeofencePendingIntent() {
    if (mGeofencePendingIntent != null) {
        return mGeofencePendingIntent;
    }
    Intent intent = new Intent(this, GeofenceBroadcastReceiver.class);
    mGeofencePendingIntent = PendingIntent.getBroadcast(this, FENCING_REQUEST_CODE, intent, PendingIntent.FLAG_UPDATE_CURRENT);
    return mGeofencePendingIntent;
}

广播接收器

public class GeofenceBroadcastReceiver extends BroadcastReceiver {

    /**
     * Receives incoming intents.
     *
     * @param context the application context.
     * @param intent  sent by Location Services. This Intent is provided to Location
     *                Services (inside a PendingIntent) when addGeofences() is called.
     */
    @Override
    public void onReceive(Context context, Intent intent) {
        // Enqueues a JobIntentService passing the context and intent as parameters
        StoreFencing.enqueueWork(context, intent);
    }
  }
}

防护服务:

public class StoreFencing extends JobIntentService {

    private static final int JOB_ID = 502;
    List<Geofence> triggeringGeofences;

    public static void enqueueWork(Context context, Intent intent) {
        enqueueWork(context, StoreFencing.class, JOB_ID, intent);
    }

    @Override
    protected void onHandleWork(@NonNull Intent intent) {

        GeofencingEvent geofencingEvent = GeofencingEvent.fromIntent(intent);
        if (geofencingEvent.hasError()) {

            return;
        }

        int geofenceTransition = geofencingEvent.getGeofenceTransition();

        if (geofenceTransition == Geofence.GEOFENCE_TRANSITION_ENTER) {

            triggeringGeofences = geofencingEvent.getTriggeringGeofences();
            getGeofenceEnterTransitionDetails(triggeringGeofences);

        }

        if (geofenceTransition == Geofence.GEOFENCE_TRANSITION_EXIT) {

            triggeringGeofences = geofencingEvent.getTriggeringGeofences();
            getGeofenceExitTransitionDetails(triggeringGeofences);

        }

    }
}

代码或设备是否有问题。通知用户在这些手机中启用其他设置。帮助解决这个问题。

是的,我也遇到过这些问题。

  1. 在 One Plus 设备上,必须禁用应用的电池优化,即必须在“设置”>“电池”>“所有应用”>“YourApp”中将其设置为 'Dont optimize'。只有这样,它才能在您的应用程序处于后台或什至不处于后台时运行。

  2. 在小米设备上,您的应用必须在设置中启用自动启动权限,地理围栏才能正常工作。

  3. 大多数其他中国设备,如联想、酷派等,在应用程序被最近杀死后也没有触发任何地理围栏转换事件。

您可以将用户重定向到设置中的特定页面,并告诉他们 enable/disable 他们以使地理围栏正常工作。

除此之外我还没有找到任何解决方案。

避免使用广播接收器,因为这些是 Oreo 及更高版本的电池优化目标。所以使用 fusedLocationProvider 是推荐的方式。另外,不要调用地理围栏 API,最好使用 Haversine 公式(用于计算坐标之间的距离)

LatLng Home = new LatLng(10.398152, 76.096864);
int Radius =100;
        fusedLocationProviderClient.getLastLocation().addOnSuccessListener(this, new OnSuccessListener<Location>() {
                    @Override
                    public void onSuccess(Location location) {
                        //Haversine formula
        
                        double longitude = location.getLongitude() - Home.longitude;
                        double latitude  = location.getLatitude() - Home.latitude;
                        double a = Math.pow(Math.sin(latitude/2),2) + Math.cos(Home.latitude)
                                *Math.cos(location.getLatitude())*Math.pow(Math.sin(longitude/2),2);
                        double circuit = 2 * Math.asin(Math.sqrt(a));
                        double eradius = 6371;
                       if(circuit*eradius<Radius){
                           Log.e("User Status","Within Geofence");
                           
                                                  }
    else{
    Log.e("User Status","User outside Geofence");
    }
