getCurrentLocationInBackground Parse.com [英] getCurrentLocationInBackground Parse.com

问题描述

我想开发应用程序，使用GPS位置的服务。应该每个服务都有一个位置（GeoPoint对象）。我试图让我的当前位置，并将其保存到数据库的解析。我试图用getCurrentLocationInBackground但遗憾的是没有关于如何使用本指南。我用下面的code可惜it't不工作。请帮助！

 无效的getLocation（）{
        // ParseGeoPoint位置= NULL;
        标准标准=新标准（）;
        criteria.setAccuracy（Criteria.ACCURACY_LOW）;
        criteria.setAltitudeRequired（假）;
        criteria.setBearingRequired（假）;
        criteria.setCostAllowed（真）;
        criteria.setPowerRequirement（Criteria.POWER_LOW）;        ParseGeoPoint.getCurrentLocationInBackground（20000，标准，新LocationCallback（）{
          @覆盖
          公共无效完成（ParseGeoPoint的GeoPoint，ParseException的E）{            如果（E == NULL）{                Toast.makeText（getApplicationContext（），geoPoint.getLatitude（）+，50000）.show（）;
            }其他{
              //处理您的错误
              e.printStackTrace（）;
              Toast.makeText（getApplicationContext（），错误，50000）.show（）;
            }
          }
        }）;
}
 

解决方案

我能够在build.grade添加以下的依赖来解决这个问题：

  {相关性
    编译com.google.android.gms：播放服务地点：7.5.0
}
 

我也不得不删除所有 ACCESS_COARSE_LOCATION 和 ACCESS_FINE_LOCATION 从AndroidManifest.xml中的权限，这似乎很奇怪。

您已经定义了标准的方式是正确的，也是必要的。

这是Parse.com API中一个非常不错的功能，但我希望他们能提供一些文件。由于是，我真的不相信它......我只是用它作为一个快速和肮脏的解决方案，直到我有时间去实现谷歌正常播放服务。

I'm trying to develop application that uses GPS locations for services. Each service should has a location (GeoPoint). I'm trying to get my current location and save it to parse database. I tried to use getCurrentLocationInBackground but unfortunately there is not guide on how to use this. I used the below code but unfortunately it't not working. Please help!

void getLocation() {


        // ParseGeoPoint location = null;
        Criteria criteria = new Criteria();
        criteria.setAccuracy(Criteria.ACCURACY_LOW);
        criteria.setAltitudeRequired(false);
        criteria.setBearingRequired(false);
        criteria.setCostAllowed(true);
        criteria.setPowerRequirement(Criteria.POWER_LOW);

        ParseGeoPoint.getCurrentLocationInBackground(20000, criteria, new LocationCallback() {
          @Override
          public void done(ParseGeoPoint geoPoint, ParseException e) {

            if (e == null) {

                Toast.makeText(getApplicationContext(), geoPoint.getLatitude()+"", 50000).show();


            } else {
              // handle your error
              e.printStackTrace();
              Toast.makeText(getApplicationContext(),"error", 50000).show();
            }
          }
        });


}

解决方案

I was able to fix this by adding the following dependency in build.grade:

dependencies {
    compile 'com.google.android.gms:play-services-location:7.5.0'
}

I also had to remove all ACCESS_COARSE_LOCATION and ACCESS_FINE_LOCATION permissions from AndroidManifest.xml, which seems very strange.

The way you have defined the Criteria is correct, and also necessary.

This is a really nice feature in the Parse.com API but I wish they would provide some documentation. As is, I don't really trust it... I'm just using it as a quick and dirty solution until I have time to implement Google Play Services properly.
