Failing to start emulator

[Jaleelahmed94]

Hello,
I am trying to start the emulator by following the Readme but I see an error where the emulator exits with code 137, I am not sure what might be causing this, I know 137 is memory issue, but what would I need to do to fix this because without the task manually I am able to boot up the emulator.

Do you wish to create a custom hardware profile? [no] 09:13:48 V/EmulatorConsole: Creating emulator console for 5680

Have you run with the --debug flag for Gradle? You'll get additional logs from the emulator starting up. Fair warning though, you will get a LOT of logs. I've usually found the emulator failing to start shows helpful kernel output from the emulator. I hooked up the debug mode for Gradle to print those logs.

Additional useful logs that I see when using the --debug flag...

Hmm, so there's a couple of things but nothing too helpful.

1. Regarding your question about the ADB ports, when you connect to a device, you actually get two ports bound. The one you specified and one above it. You can see more detail about this here: https://developer.android.com/studio/command-line/adb#howadbworks

The server then sets up connections to all running devices. It locates emulators by scanning odd-numbered ports in the range 5555 to 5585, the range used by the first 16 emulators. Where the server finds an adb daemon (adbd), it sets up a connection to that port. Note that each emulator uses a pair of sequential ports — an even-numbered port for console connections and an odd-numbered port for adb connections. For example:

Emulator 1, console: 5554
Emulator 1, adb: 5555
Emulator 2, console: 5556
Emulator 2, adb: 5557
and so on...

As shown, the emulator connected to adb on port 5555 is the same as the emulator whose console listens on port 5554.

2. The WARNING | the -no-skin flag is obsolete. to have a non-skinned virtual device, create one through the AVD manager is perfectly fine and is known to not cause issues. This flag is just always passed by the plugin to speed up the startup on older emulators.
3. My guess is that WARNING | cannot add library /Users/myUser/Library/Android/sdk/emulator/qemu/darwin-x86_64/lib64/vulkan/libvulkan.dylib: failed is the real reason why your emulator is failing during bootup. I don't know what the solution is but recommend googling around and see if you can figure out what flags you may need to pass that are different from what you have when running via Android Studio.

I hope this helps!
