问题描述

SDK:Android 5.0.1.

SDK: Android 5.0.1.

Android 版本:LRX22C.

Android build: LRX22C.

设备:Nexus 5.

Device : Nexus 5.

问题:奇巧 (4.4.4) 及以下 API 的

Problem: KITKAT(4.4.4) and below API's

1) startUsingNetworkFeature(int networkType, String feature)此方法已弃用.已弃用，取而代之的是更简洁的 requestNetwork(NetworkRequest, ConnectivityManager.NetworkCallback).

1) startUsingNetworkFeature(int networkType, String feature) This method is deprecated. Deprecated in favor of the cleaner requestNetwork(NetworkRequest, ConnectivityManager.NetworkCallback).

2) requestRouteToHost(int networkType, int hostAddress)此方法已弃用.不推荐使用 requestNetwork(NetworkRequest, ConnectivityManager.NetworkCallback)、setProcessDefaultNetwork(Network) 和 getSocketFactory().

2) requestRouteToHost(int networkType, int hostAddress) This method is deprecated. Deprecated in favor of the requestNetwork(NetworkRequest, ConnectivityManager.NetworkCallback), setProcessDefaultNetwork(Network) and getSocketFactory().

用于在WIFI和移动数据开启时通过移动数据网络发送请求.

were used to send request over Mobile Data Network when WIFI and mobile data were on.

从 Android L 开始，API 已弃用且不再有效.

Starting Android L the API's is deprecated and no longer work.

新 API 的/类 NetworkRequest.Builder、NetworkRequest、ConnectivityManager.NetworkCallback、requestNetwork、使用了 registerNetworkCallback.此处详细介绍 API 使用
Android L API

New API's/Classes NetworkRequest.Builder, NetworkRequest, ConnectivityManager.NetworkCallback, requestNetwork, registerNetworkCallback were used. Detail Here on API usage
Android L API's

代码:

ConnectivityManager connectivityManager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);

NetworkRequest.Builder builder = new NetworkRequest.Builder();

builder.addCapability(NetworkCapabilities.NET_CAPABILITY_NOT_RESTRICTED);
builder.addTransportType(NetworkCapabilities.TRANSPORT_CELLULAR);

NetworkRequest networkRequest = builder.build();
connectivityManager.requestNetwork(networkRequest, networkCallback);
connectivityManager.registerNetworkCallback(networkRequest, networkCallback);

工作场景:

仅接收 onAvailable 回调上的移动数据.

Only mobile data on onAvailable callback is received.

不工作场景:移动和 Wifi 均已打开并已连接，未从系统收到 onAvailable 回调.因此无法设置 setProcessDefaultNetwork，ConnectivityManager.setProcessDefaultNetwork(preferedNetwork);

Not working Scenario: Both Mobile and Wifi is on and connected, onAvailable callback is not received from system. Hence not able to set setProcessDefaultNetwork, ConnectivityManager.setProcessDefaultNetwork(preferedNetwork);

经常:总是

预期输出:在 wifi 开启时获取移动网络 avaliabe 回调.

Expected output: Get mobile network avaliabe callback when wifi is on.

是我遗漏了什么还是固件有问题?

Am I missing something here or the firmware has some issues here?

Google 错误引发 1 Google 错误引发 2 有什么作用没有为此更改输入评论"是谷歌的意思吗?

Google bug raised 1 Google bug raised 2 What does "No comment was entered for this change" mean from google?

推荐答案

终于找到了解决方案.技巧是将功能用作NET_CAPABILITY_INTERNET.与 startUsingNetworkFeature(ConnectivityManager.TYPE_MOBILE, FEATURE_ENABLE_HIPRI);

Well finally found solution for this. Trick was to use capability as NET_CAPABILITY_INTERNET. Which is same as startUsingNetworkFeature(ConnectivityManager.TYPE_MOBILE, FEATURE_ENABLE_HIPRI);

在这里查看固件设计

builder.addCapability(NetworkCapabilities.NET_CAPABILITY_INTERNET);
builder.addTransportType(NetworkCapabilities.TRANSPORT_CELLULAR);

此后，我可以从系统获得 onAvailable 回调，然后我将我的流程默认网络设置为移动数据.

After this I am able to get onAvailable callback from system and later I set my process default network as mobile data.

因此，即使 wifi 已打开，所有请求也会通过移动数据传输.哇！

Hence all the request goes over mobile data even if wifi is on. WOW!

注意:这在 Preview L 的初始版本中不起作用.

Note: This was not working in initial releases of Preview L.

编辑 19-10-2015:setProcessDefaultNetwork 现已弃用，使用 bindProcessToNetwork

Edit 19-10-2015: setProcessDefaultNetwork is now depcreated use bindProcessToNetwork
