Android Emulator gives an Error SO_REUSEPORT and debugging not working

Question

I am getting following error when running emulator, also debugging is not working, it says waiting for debugger to attach. I am wondering if the following has anything to do with getting stuck at "waiting for debugger to attach".

Emulator: E0516 21:01:34.057349753 3279 socket_utils_common_posix.cc:201] check for SO_REUSEPORT: {"created":"@1589644894.057229268","description":"SO_REUSEPORT unavailable on compiling system","file":"/mnt/tmpfs/src/android/emu-master-dev/external/grpc/src/core/lib/iomgr/socket_utils_common_posix.cc","file_line":169}

My android studio version is below.

Android Studio 3.6.3 Build #AI-192.7142.36.36.6392135, built on April 14, 2020 Runtime version: 1.8.0_212-release-1586-b4-5784211 amd64 VM: OpenJDK 64-Bit Server VM by JetBrains s.r.o Linux 5.4.0-29-generic GC: ParNew, ConcurrentMarkSweep Memory: 1246M Cores: 4 Registry: ide.new.welcome.screen.force=true Non-Bundled Plugins:

Answer 1

I had that problem.

I was making a wrong diagnostic.

Running the emulator from Android/Sdk/emulator/emulator with a command such as:

./emulator @Pixel_3_API_28 -netdelay none -netspeed full -debug all also gave me this error, but it is non-blocking.

The problem disappeared when I:

• switched to proprietary driver (nvidia) in Ubuntu in the Software Updater > Settings > Additional Driver

• Restarting

• Recreating my virtual device.

Answer 2

For me the device was working fine until this error started coming up.

Android Studio -> Open AVD Manager -> Select Virtual Device -> Wipe Data fixed the issue for me.
