android - WIFI开启时通过移动数据发送请求。(Android L)

Question

SDK:Android 5.0.1。

Android 版本:LRX22C。

设备:Nexus 5。

问题:KITKAT(4.4.4) 及以下API的

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)。

2) requestRouteToHost(int networkType, int hostAddress)此方法已弃用。已弃用，取而代之的是 requestNetwork(NetworkRequest, ConnectivityManager.NetworkCallback)、setProcessDefaultNetwork(Network) 和 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。

从 Android L 开始，API 已弃用且不再有效。

新 API/类 NetworkRequest.Builder、NetworkRequest、ConnectivityManager.NetworkCallback、requestNetwork、使用了 registerNetworkCallback。 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。

不工作场景:Mobile 和 Wifi 均已开启并已连接，未收到来自系统的 onAvailable 回调。因此无法设置 setProcessDefaultNetwork，ConnectivityManager.setProcessDefaultNetwork(preferedNetwork);

经常:总是

预期输出:wifi 开启时获取移动网络可用回调。

是我遗漏了什么还是固件有问题？

Answer 1

终于找到了解决方案。诀窍是使用功能作为 NET_CAPABILITY_INTERNET。与 startUsingNetworkFeature(ConnectivityManager.TYPE_MOBILE, FEATURE_ENABLE_HIPRI);

相同

See the Firmware design here

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

在此之后，我能够从系统获取 onAvailable 回调，然后我将进程默认网络设置为移动数据。

因此，即使 wifi 开启，所有请求也会通过移动数据传输。哇!

注意:这在 Preview L 的初始版本中不起作用。
