Looks like a SSL problem after all ?
Well, I've done more dumps. It appears that even when the connection
is working, I can see this strange behavior of [RST]. The difference
is that just after the [RST], a new [SYNC] is done and the connection
works again.
After going out of sleep mode there's
Kinda reading between the lines in the first link you posted, I had a
thought... Is your client sending more data in the HTTP request than the
server expects?
There are two more things I would try:
- Shut down the output side of your connection on the Android side after
you've sent the
The request I make is from GET type, so I've no output and I think
that it's not possible to send more data than expected. Correct me if
I'm wrong.
The request I make is exactly the same on Android and Windows Mobile
and with WM, the server react correctly. The request seems to be good.
Anyway,

By calling socket.shutdownOutput you are specifically telling the SSL
code that your application will not be
I've looked at what's happening on the server. The server is as

Here's what I've got from Wireshark:

Looking at the Wireshark dump, it looks like the server begins to
close the connection before the phone falls asleep:
It's the FIN/ACK packet #212994 - highlighted in grey.
The phone is supposed to send ACK (which it does) and then its own
FIN/ACK, confirming the close (which it does not).
There's nothing in logcat apart from garbage collector actions.
I'm already listening to ConnectivityManager
(ConnectivityManager.CONNECTIVITY_ACTION) and TelephonyManager
(PhoneStateListener.LISTEN_DATA_CONNECTION_STATE) events to track
network modifications. Nothing is caught when the problem
Hello Kostya,
I've tried what you said but my problem remains. I'm fact the problem
only occurs when the device goes in sleep mode. If I let it connected
to my PC (the screen never goes totally black), every thing is working
fine. I've got a wakeLock in my application:
final PowerManager pm =
Does the server think it still has a valid connection at this point?

Oh, and check the logcat - I think you should see connection manager events
at the time your connection goes bad.

New information:
It seems that I don't receive Connection Reset by Peer errors because
Android has dropped the connection.
My exact test case is the following:
- I start my application which creates the request with the previous
posted code
- the app reads the request response waiting for the
Like I said before, detecting a broken connection on the receiving end
is difficult, since TCP/IP does not have keep-alives. That's left up to
the application protocol.
Perhaps what you could do is have your application periodically send
small amounts of data, just to make sure the
