Android位置管理器错误'正在退出错误onLocationChanged第152行"1"'

Question

我的Android应用中有一位位置管理器,有时会有效.有时我会运行应用程序,它会获得位置更新(有一些错误).有时我会运行它,它会在几秒钟内抛出此错误,而不会收到任何位置更新:

E/IzatSvc_PassiveLocListener: Exiting with error onLocationChanged line 152 "1"

这是我管理位置事件的课程:

package com.company.AppName;

import android.app.job.JobParameters;
import android.app.job.JobService;
import android.content.Context;
import android.content.Intent;
import android.location.Criteria;
import android.location.Location;
import android.location.LocationManager;
import android.os.Bundle;
import android.util.Log;

public class LocationListenerService extends JobService {
  private static final String TAG = "LocationListenerService";
  private LocationManager locationManager = null;
  private LocationListener locationListener = null;
  private String locationProvider = null;

  public LocationListenerService() {}

  @Override
  public int onStartCommand(Intent intent, int flags, int startId) {
    return START_STICKY;
  }

  @Override
  public boolean onStartJob(JobParameters params) {
    Log.i(TAG, "onStartJob");
    startLocationManager(params);
    return true;
  }

  @Override
  public boolean onStopJob(JobParameters params) {
    Log.i(TAG, "onStopJob");
    return false;
  }

  public void startLocationManager(JobParameters params) {
    if(locationManager != null) return;

    Criteria criteria = new Criteria();
    criteria.setAccuracy(Criteria.ACCURACY_FINE);
  //    criteria.setPowerRequirement(Criteria.POWER_LOW);
    criteria.setAltitudeRequired(false);
    criteria.setBearingRequired(false);

    locationManager = (LocationManager) getApplicationContext().getSystemService(Context.LOCATION_SERVICE);
    locationProvider = locationManager.getBestProvider(criteria, true);
    locationListener = new LocationListener();

    if (locationProvider != null) {
      Log.v(TAG, "Location provider: " + locationProvider);
    } else {
      Log.e(TAG, "Location provider is null. Location events will not work.");
      return;
    }

    if (locationListener == null) {
      Log.e(TAG, "Location listener is null. Location events will not work.");
      return;
    }

    // Finish job after first time updating location with the server
    NativeApp.shared().getLocationData((NativeApp app, String response) -> {
      Log.i(TAG, "Received location data response. Finishing job.");
      jobFinished(params, true);
    });

    try {
      locationManager.requestLocationUpdates(locationProvider, 0, 0, locationListener);
    } catch (java.lang.SecurityException ex) {
      Log.e(TAG, "fail to request location update, ignore", ex);
    } catch (IllegalArgumentException ex) {
      Log.e(TAG, "network provider does not exist, " + ex.getMessage());
    }
  }

  private class LocationListener implements android.location.LocationListener {
    @Override
    public void onLocationChanged(Location location) {
      if(location == null) {
        Log.w(TAG, "onLocationChanged skipped: null location");
        return;
      }
      Log.i(TAG, "onLocationChanged: " + location.toString());
      NativeApp.shared().updateLocation(location);
    }

    @Override
    public void onProviderDisabled(String provider) {
      Log.i(TAG, "onProviderDisabled: " + provider);
    }

    @Override
    public void onProviderEnabled(String provider) {
      Log.i(TAG, "onProviderEnabled: " + provider);
    }

    @Override
    public void onStatusChanged(String provider, int status, Bundle extras) {
      Log.i(TAG, "onStatusChanged: " + provider);
    }
  }
}

为什么会这样？为什么有时会更新位置更新,但有时却不行？

编辑:放弃几个小时并重新运行后,应用程序仍然重复抛出错误,但大约10秒后记录此并开始接收位置更新:

E/XTCC-6.1.2.10: [FDAL_OSListener] handleLocationUpdate:  failed: 2
D/LocationManagerService: incoming location: gps
I/LgeGnssLocationProvider: Intent - android.location.GPS_FIX_CHANGE
D/LgeGnssLocationProvider: GPS_FIX_CHANGE_ACTION! , mGpsNavigating =true
D/LocationManagerService: incoming location: gps

设备/版本信息:

该设备是运行Android 8.0.0的LG G6(LG-H872)

Answer 1

long milliseconds = 5000; // 5 seconds
float minimusDistance = 5.5; // 5.5m distance from current location
locationManager.requestLocationUpdates(locationProvider, milliseconds, minimusDistance, locationListener);

试试这个片段。希望它能解决你的问题。

这只是发生，因此，您没有提供获取位置更新的最小间隔和最小距离。这就是您收到此错误的原因。

这是检查出来的链接 - requestLocationUpdates

Answer 2

此位置更新根据 Android 版本而有所不同。最近 Android在oreo中引入了后台位置限制，其中表示：

当您的应用程序位于前台时，您应该按照您的请求频繁地接收位置更新。当您的应用进入后台时，您的应用每小时只会收到几次位置更新（未来可能会根据系统影响和开发者的反馈调整位置更新间隔）。

Android 建议使用融合位置 API 的原因如下，您必须根据您的场景考虑它：

如果您的应用需要访问包含频繁更新的位置历史记录，请使用 Fused Location Provider API 元素的批处理版本，例如 FusedLocationProviderApi 接口。当您的应用程序在后台运行时，此 API 比非批处理 API 更频繁地接收用户位置。但请记住，您的应用程序每小时仍只能接收几次批量更新。

请参阅以下链接以获取更好的方法：

https://codelabs.developers.google.com/codelabs/background-location-updates-android-o/index.html#0

注意：“O”后台位置限制仅在您的应用程序不再位于前台时才会生效。

如果以上两个链接不适合您，请告诉我。
