Android Geofencing无法在OnePlus,Xiaomi等某些移动设备上触发

我在Android文档的指导下使用地理围栏代码。已在Sony XA1,Samsung J7 Nxt,Xiaomi 5A,Poco f1,OnePlus 6等真实设备中进行了测试。 J7 Nxt。

小米 OnePlus 移动版中发行。

  1. 在小米5A中,一段时间 Enter 可以正常工作,但 Exit 不会触发。
  2. 在Xiaomi Poco f1中, Enter Exit 均不起作用。
  3. 在OnePlus Mobile中,仅当打开应用程序时才起作用。

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);
    }
  }
}

击剑服务:

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);

        }

    }
}

代码或设备是否存在任何问题。通知用户在这些移动设备中启用其他设置。帮助解决此问题。

是的,我也遇到了这些问题。

  1. 在One Plus设备上,必须禁用应用程序的电池优化,即必须在“设置”>“电池”>“所有应用程序”>“ YourApp”中将其设置为“不优化”。只有这样,当您的应用程序在后台或什至不在后台时,它才能工作。

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

  3. 大多数其他中国设备(例如Lenovo,Coolpad等)在从最近的应用程序中被杀死后,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,并告诉他们启用/禁用他们以便地理围栏正常工作。

除此之外,我没有找到任何解决方案。

避免使用广播接收器,因为它们是 Oreo 及更高版本电池优化的目标。所以使用 fusedLocationProvider 是推荐的方式。另外不要调用Geofencing 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");
    }
