Hello, I am trying to send a fil from the phone to a server on a
desktop. I wrote some code, which works on emulator, but on the phone
it doesn`t. I`m connecting to the network through WiFi. It works, I
can access the internet through my phone and I`ve configured my
router. The application stops when I`m trying to connect. I have the
permissions. Someone have any ideas, below is my code.
