I need to add

hw.audioInput=no hw.audioOutput=no

to every AVD I create. Otherwise, the Android Emulator uses 100% CPU all the time, even when it's been idle for minutes.

I'm far from the only one having the problem, see https://stackoverflow.com/questions/37063267/high-cpu-usage-...

I'm on a Macbook Air 2014, Intel i5, 8GB of RAM, 500GB SSD. Hardware acceleration, etc. all enabled.

And here's the promised emulator build (from aemubins gmail account that we use to distribute debug binaries like this):

If you still don't get symbols from that it should be possible to build the emulator itself on macos:

install repo from depot_tools https://www.chromium.org/developers/how-tos/install-depot-to...

    pip install absl-py
    pip install urlfetch
    mkdir emu
    cd emu
    repo init -u https://android.googlesource.com/platform/manifest -b emu-master-dev --depth=1
    repo sync -qcj 4
    cd external/qemu
    python android/build/python/cmake.py

    # run
    objs/emulator -avd avdName -no-snapshot

Debugging:

    # when it spins:

    # method 1: go to activity monitor -> sample process, send over the result

    # method 2: lldb
    lldb
    process attach --pid <pid-of-qemu-system-<arch>>
    bt all #send it over

    # method 3: guest process taking CPU
    adb shell top

Sorry, I'm not an expert. What am I supposed to do with the emulator-symbols.zip?

Interesting, sounds like a live loop in some audio thread somewhere. What's your audio setup and AVD config.ini? I might be able to reproduce on my Mac.
