Connection Refused in WearableListenerService / Android Wear when phone in sleep mode -

-

i developing android wear watchface accesses internet sending messageapi request wear mobile app, running wearablelistenerservice, , on mobile app, receive request wear in onmessagereceived, , in onmessagereceived start asynctask retrieve image internet.

this works fine normally.

however, if phone inactive few minutes (screen black, not connected mac via usb) receive "econnrefused - connection refused server", when asynctask tries retrieve inputstream on line:

inputstream = (inputstream) new url(murl).getcontent();

here exception:

  • my app retries minute later, , when phone on (screen on), works!
  • it has nothing server/the url calling, getting same error different servers.
  • it has nothing wifi, because happens regardless if in wifi or normal network.
  • this happens in prod/signed , debug version
  • i checking if network available right before call, , getting "true", network indeed on!

public boolean isnetworkavailable() {     connectivitymanager cm = (connectivitymanager)             getsystemservice(context.connectivity_service);     networkinfo networkinfo = cm.getactivenetworkinfo();     // if no network available networkinfo null     // otherwise check if connected     if (networkinfo != null && networkinfo.isconnected()) {         return true;     }     return false; }

it looks problem can solved acquiring wakelock - did not solve problem far.

any appreciated!!!

android 4.4.4 sony xperia z1; android wear 5.0.2.

solved: turns out, reason energy saving options on xperia: set "stamina-modus", caused device not wake up.
