Since some time I get a very strange error log, this does not make sense, since I do not use GRPC in my project.
A log is sent every second to logcat as follows:
...
05-16 10:53:13.249 24321-24368/my.package E/GRPC: tcp_client_posix.c:173] failed to connect to 'ipv4:127.0.0.1:12389': socket error: connection refused
05-16 10:53:14.249 24321-24368/my.package E/GRPC: tcp_client_posix.c:173] failed to connect to 'ipv4:127.0.0.1:12389': socket error: connection refused
05-16 10:53:15.254 24321-24367/my.package E/GRPC: tcp_client_posix.c:173] failed to connect to 'ipv4:127.0.0.1:12389': socket error: connection refused
...
Since this does not lead to an application crash or application delay, it is very unpleasant when viewing the logarithm.
I suspect this has something to do with my OS, ubuntu 16.04 LTS, because this error log is missing when the project is running on Windows.
The problem is not device related, as I tried to use many devices, and I always see it.
If you need more information, I have provided it. Thanks in advance.
