AndroidApp: Sometimes socket closure is not detected

[madmaxoft]

Sometimes the app doesn't detect socket closure, which results in the app running in busy-loop (select - got 1 socket - read 0 bytes - repeat) and at the same time the app won't connect to the remote peer because it's still blacklisted.

When the connection is closed properly, the Channel.read() method returns -1, which isn't detected in the code.
