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

1)startUsingNetworkFeature(int networkType, String feature) 不推荐使用此方法.不赞成使用清洁剂requestNetwork(NetworkRequest, ConnectivityManager.NetworkCallback).

2)requestRouteToHost(int networkType, int hostAddress) 不推荐使用此方法.贬低赞成requestNetwork(NetworkRequest, ConnectivityManager.NetworkCallback),setProcessDefaultNetwork(Network)和getSocketFactory().

用于在WIFI和移动数据打开时通过移动数据网络发送请求.

启动Android L后,API已弃用,不再有效.

新的API /类NetworkRequest.Builder,NetworkRequest,ConnectivityManager.NetworkCallback,requestNetwork,registerNetworkCallback分别使用. 详细信息这里有关于API使用
Android L API的信息

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onAvailable接收回调上的移动数据.

不工作场景:移动和Wifi都已打开并连接,onAvailable未从系统接收回叫.因此无法设置setProcessDefaultNetwork, ConnectivityManager.setProcessDefaultNetwork(preferedNetwork);

经常:永远

预期输出:当wifi打开时获取移动网络avaliabe回调.

我在这里遗漏了什么或固件有问题吗？

Answer 1

好吧终于找到了解决方案.特技是使用能力NET_CAPABILITY_INTERNET.哪个是一样的startUsingNetworkFeature(ConnectivityManager.TYPE_MOBILE, FEATURE_ENABLE_HIPRI);

请在此处查看固件设计

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

在此之后,我能够onAvailable从系统获得回调,之后我将我的流程默认网络设置为移动数据.

因此即使wifi打开,所有请求都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.
