Always TimeoutException on Android

[ghost]

I'm developing on Android and i've tested my app on emulator and real device. At first i've used the last jar distributed, but after some timeout exception i've seen other issue and i've reverted to the v11 implementation.
Now i'm sending the code to my phone, switching datacenter and then sign in with phone, phone's hashcode and signkey but it always return me timeout exception.
I'm also following the guideline on the Telegram docs and it seems to be the good way, also the docs tell me that it should return error, but it will return me always timeout exception.
There's a way to get out of this? I'm getting mad, i don't know if i'm missing something or if the api are inconsistent.
