What 're opened TCP port android need to be connected on? We've an android TV connected on a restricted WIFI network. Its IP adress is fixed. My problem only the web browser is working well. All other application can not go on the web or synchronize.
We got this netstat: 

 u0_a67@android:/ $ netstat

Regarding on the web information, we opened the TCP port 5228 in OUTPUT mode and we opened the  TCP port 38388 in INPUT mode as it's in listen status in the netstat.

That doesn't solve the problem.
Any idea about the list of TCP port need to be opened on the network for android working?

Thanks for help.
I solved my problem configuring the closest time than universal time,  manually.  Google play connected itself well. After I configured  the ntp server in the network.
