    Exclamation Android Client Reconnection

    I was evaluating lightstreamer for our use case hence setup lighstreamer server with demo licence using Lightstreamer 7.0.0 build 20180228. Server setup was fine and working. For android client I was trying the reconnect scenario in case user lose internet connectivity and then regain connectivity. For this on android client i manually turned off internet and few seconds later I turned the internet on, but the client did not reconnected and gave status as disconnected as soon as internet connectivity was restored. I enabled logging on android client and will be posting the logs below but the unexpected thing which came was the below logs:

    Response status: 200
    HTTP transport receiving [6872be06]:
    CONERR,4,Insufficient data for recovery
    New message: CONERR,4,Insufficient data for recovery
    HTTP channel released [6872be06]
    Error event while SLEEP reason: recovery.error
    (recovery.error) Unexpected error event while session is an non-active status: SLEEP
    Session state change: SLEEP -> OFF
    Protocol dismissed

    On server side I saw the following logs:
