"LocationManager 提供程序类型？"

Question

I was trying out the LocationManager<\/code><\/a> .我正在尝试LocationManager<\/code><\/a> 。 It lists only 3 providers GPS|NETWORK|PASSIVE_PROVIDER<\/code> in documentation.它在文档中仅列出了 3 个提供商GPS|NETWORK|PASSIVE_PROVIDER<\/code> 。

I used criteria<\/code> to get best possible location update.我使用criteria<\/code>来获得最佳的位置更新。

        Criteria criteria = new Criteria();
        criteria.setAccuracy(Criteria.ACCURACY_FINE);
        locationManager.requestLocationUpdates(0, 0, criteria, locationListener, null);

Answer 1

I haven't seen this specific issue, but as of Android 11 on some devices it appears getBestProvider<\/code> can return fused<\/code> and getProviders()<\/code> can as well.我还没有看到这个特定的问题，但从 Android 11 开始，在某些设备上似乎getBestProvider<\/code>可以返回fused<\/code>并且getProviders()<\/code>也可以。

Notable, PROVIDER_FUSED<\/code> was added as a constant in Api 31 https:\/\/developer.android.com\/reference\/android\/location\/LocationManager#FUSED_PROVIDER<\/a>值得注意的是， PROVIDER_FUSED<\/code>作为常量添加到 Api 31 https:\/\/developer.android.com\/reference\/android\/location\/LocationManager#FUSED_PROVIDER<\/a>

Anyhow, I did some testing of getProviders(true)<\/code> and getBestProviders(Criteria(FINE_LOCATION), true)<\/code> that may prove useful:无论如何，我对getProviders(true)<\/code>和getBestProviders(Criteria(FINE_LOCATION), true)<\/code>进行了一些测试，这可能证明是有用的：
