Android LocationServices.FusedLocationApi 已弃用

我不明白为什么LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient,mLocationRequest, this);“FusedLocationApi”被划掉并指出它已被弃用。点击此处查看图片 https://i.stack.imgur.com/mML1U.jpg

            .findFragmentById(R.id.map);
    mapFragment.getMapAsync(this);

原答案

发生这种情况是因为FusedLocationProviderApi在最新版本的 Google Play 服务中已弃用。你可以检查一下here https://developers.google.com/android/reference/com/google/android/gms/location/FusedLocationProviderApi。官方指南现在建议使用融合位置提供者客户端 https://developers.google.com/android/reference/com/google/android/gms/location/FusedLocationProviderClient。你可以找到详细的指南here https://developer.android.com/training/location/retrieve-current.html#play-services.

例如在里面onCreate() or onViewCreated()创建一个FusedLocationProviderClient实例

Kotlin

val fusedLocationClient = LocationServices.getFusedLocationProviderClient(requireContext())

要请求最后的已知位置，您所要做的就是致电

fusedLocationClient.lastLocation.addOnSuccessListener { location: Location? ->
            location?.let { it: Location ->
                // Logic to handle location object
            } ?: kotlin.run {
                // Handle Null case or Request periodic location update https://developer.android.com/training/location/receive-location-updates
            }
        }

Java

FusedLocationProviderClient fusedLocationClient = LocationServices.getFusedLocationProviderClient(requireContext());

and

fusedLocationClient.getLastLocation().addOnSuccessListener(requireActivity(), location -> {
        if (location != null) {
            // Logic to handle location object
        } else {
            // Handle null case or Request periodic location update https://developer.android.com/training/location/receive-location-updates
        }
    });

很简单，不是吗？

重要更新（2017 年 10 月 24 日）：

昨天谷歌更新了其官方开发者页面一个警告 https://developer.android.com/training/location/retrieve-current.html说的是

请继续使用 FusedLocationProviderApi 类，并且不要迁移到 FusedLocationProviderClient 类，直到 Google Play 服务版本 12.0.0 可用（预计将于 2018 年初发布）。在 12.0.0 版本之前使用 FusedLocationProviderClient 会导致客户端应用程序崩溃设备上的 Google Play 服务已更新。对此造成的任何不便，我们深表歉意。

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

最新更新（2017 年 11 月 21 日）：

The warning is gone now. Google Play services 11.6 November 6, 2017, release note https://developers.google.com/android/guides/releases says : I think Play Services won't crash when it updates itself in the background. So we can use new FusedLocationProviderClient now.
