Android LocationServices.FusedLocationApi已弃用

问题描述

我无法弄清楚为什么 LocationServices.FusedLocationApi.requestLocationUpdates（mGoogleApiClient，mLocationRequest，this）; FusedLocationApi交叉指出并指出它已被弃用。
我认为Play Services在后台自动更新时不会崩溃。所以我们现在可以使用新的 FusedLocationProviderClient 。

重要更新（2017年10月24日）：

昨天Google通过
所以我我们认为我们应该继续使用已弃用的 LocationServices.FusedLocationApi ，直到Google解决问题为止。

原始答案

发生这种情况是因为 FusedLocationProviderApi 在最新版本的Google Play服务中已弃用。您可以查看。官方指南现在建议使用。您可以在找到详细指南。

例如内部 onCreate（）创建 FusedLocationProviderClient 实例

  mFusedLocationClient = LocationServices.getFusedLocationProviderClient（this）; 
  

并且要申请最后一个已知位置，您只需致电

  mFusedLocationClient.getLastLocation（）
 .addOnSuccessListener（this，new OnSuccessListener< Location>（）{
 @Override 
 public void onSuccess（位置位置）{
 //得到上一个已知位置。在极少数情况下，这可以为null。
 if（location！= null）{
 //处理位置的逻辑对象
} 
} 
}）; 
  

简单不是吗？

I couldn't figure out why LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient,mLocationRequest, this); "FusedLocationApi" is cross out and point at it saying is deprecated.Click here to view Image

解决方案

Latest Update (November 21, 2017):

The warning is gone now. I think Play Services won't crash when it updates itself in the background. So we can use new FusedLocationProviderClient now.

Important Update (October 24, 2017):

Yesterday Google updated its official developer page with a warning that says

So I think we should continue using the deprecated LocationServices.FusedLocationApi until Google resolves the issue.

Original Answer

This is happening because FusedLocationProviderApi deprecated in a recent version of google play services. You can check it here. The official guide now suggests using FusedLocationProviderClient. You can find the detailed guide here.

for e.g inside onCreate() create a FusedLocationProviderClient instance

 mFusedLocationClient = LocationServices.getFusedLocationProviderClient(this);

and for requesting the last known location all you have to do is call

mFusedLocationClient.getLastLocation()
    .addOnSuccessListener(this, new OnSuccessListener<Location>() {
        @Override
        public void onSuccess(Location location) {
            // Got last known location. In some rare situations, this can be null.
            if (location != null) {
                // Logic to handle location object
            }
        }
    });

Simple isn't it?
