Question

I am using a thread launched from android local Service,after I let my phone goes to sleep mode,then reuse it later after a while I get connection reset in my server side.

I am looking why it happens that connection reset,looking for this for a days ago.

Answer 1

I have the same problem, and the server also gets a RST when it send some ping packet to android phone after phone’s several minutes sleep.

I think the post below may answer some questions:

What network are you using (phone network or WIFI)?

My phone is connect via EDGE network.
I made the server send message every 6 minutes, and the server always get RST after the first 6 minutes, but 5 minutes will keep the connection alive. And I also tried to let the server sent message every 2 minutes (phone’s screen is off), the connection can keep alive for a long time (I tested for one hour and more).

Then I keep the phone’s screen on (it will not sleep) and tried again, but after 6 minutes the connection was killed again (server got RST), so it seems android sleep is not the cause of RST.

Based on my testings, I think my phone network vender is killing these long-time connections that idle at least 6 minutes, and send the RST to both phone and server.
So it may have nothing to do with phone sleep.

I havn’t tested on other networks, please tell me the results if you do.
