问题： 奇巧（4.4.4）及以下的API
Problem: KITKAT(4.4.4) and below API's
1）startUsingNetworkFeature（INT NETWORKTYPE，字符串功能） 这种方法去precated。德precated有利于清洁requestNetwork的（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） 这种方法去precated。德precated赞成requestNetwork（NetworkRequest，ConnectivityManager.NetworkCallback），setProcessDefaultNetwork（网络），并在getSocketFactory的（）。
2)requestRouteToHost(int networkType, int hostAddress) This method is deprecated. Deprecated in favor of the requestNetwork(NetworkRequest, ConnectivityManager.NetworkCallback), setProcessDefaultNetwork(Network) and getSocketFactory().
被用来发送请求了移动数据网络时，WIFI和移动数据上。
were used to send request over Mobile Data Network when WIFI and mobile data were on.
开始的Android L时API的是德precated，不再工作。
Starting Android L the API's is deprecated and no longer work.
新的API /班NetworkRequest.Builder,NetworkRequest,ConnectivityManager.NetworkCallback,requestNetwork,registerNetworkCallback被使用。 这里详细的API使用 Android大号的API
New API's/Classes NetworkRequest.Builder,NetworkRequest,ConnectivityManager.NetworkCallback,requestNetwork,registerNetworkCallback were used. Detail Here on API usage Android L API's
code：
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);
工作方案：
在onAvailable回调唯一的移动数据接收。
Only mobile data on onAvailable callback is received.
不工作方案： 移动和无线上并连接，onAvailable回调不会从system.Hence收到无法设置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：始终
期望的输出：获得移动网络avaliabe回调时，WiFi是在
Expected output: Get mobile network avaliabe callback when wifi is on.
我缺少的东西在这里或固件存在一些问题吗？
Am i missing something here or the firmware has some issues here?

推荐答案
好了this.Trick终于找到了解决办法就是使用能力作为NET_CAPABILITY_INTERNET.Which是一样的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);"
看到这里固件设计
builder.addCapability(NetworkCapabilities.NET_CAPABILITY_INTERNET);
builder.addTransportType(NetworkCapabilities.TRANSPORT_CELLULAR);
在此，我能够得到onAvailable回调的系统，后来我把我的过程中默认的网络移动数据。
After this i am able to get onAvailable callback from system and later i set my process default network as mobile data.
因此，所有的请求都要通过移动数据，即使WiFi是on.WOW！
Hence all the request goes over Mobile data even if wifi is on.WOW!
请注意：这是不工作的preVIEW大号最初发布
Note: This was not working in initial releases of Preview L.
编辑19-10-2015： setProcessDefaultNetwork现在depcreated使用bindProcessToNetwork
Edit 19-10-2015: setProcessDefaultNetwork is now depcreated use bindProcessToNetwork
