networking - Android: ProcessBuilder not bind to network (ConnectivityManager.bindProcessToNetwork set) -


i working on project needs evaluate wifi connections.

as smartphone may have data connection well, check every connection network bound type_wifi:

boolean bound = false; if (build.version.sdk_int >= build.version_codes.m) {    bound = cm.bindprocesstonetwork(wifinetwork);      // m , above  } else if (build.version.sdk_int >= build.version_codes.lollipop) {    bound = cm.setprocessdefaultnetwork(wifinetwork)  }  .....

it works fine far, when using httpurlconnection, okhttp-lib , webview.

however, need test icmp requests, , therefore use system ping this:

 process process = new processbuilder()                 .command("/system/bin/ping", "-c 3", url)                 .redirecterrorstream(true)                 .start();

unfortunately, new process not bound network. (although have assumed , hoped was.)

it possible create socket bound required network, how use socket call ping?

there related question here not familiar file descriptor , have basic c knowledge. if somehow possible, prefer solution working without native code. nevertheless, didn't figure out how native solution work out either , happy suggestions!
