[Android Q&A, Help & Troubleshooting] michelangelo86:
I had modified the aosp generic version 6.0.71r in order for the emulator and the host to be able to used tcp streams for gpu host, but I am getting the error below. Can someone help me to understand what else I need to modified? Clearly said that it cannot connect to the tcp stream that mean on the emulator I have to change some parameters as well?

OpenglSystemCommon/HostConnection.cpp

/* Set to 1 to use a QEMU pipe, or 0 for a TCP connection */

#define USE_QEMU_PIPE 1
