PANIC: Avd's CPU Architecture 'arm64' is not supported by the QEMU2 emulator on x86_64 host

Question

When I try to run on windows this command :

emulator.exe -avd android13

Where android13 is an arm64 avd I receive the error :

INFO    | Android emulator version 31.3.13.0 (build_id 9189900) (CL:N/A)
emulator: INFO: Found systemPath c:\Users\zeus\AppData\Local\Android\Sdk\system-images\android-33\google_apis\arm64-v8a\
PANIC: Avd's CPU Architecture 'arm64' is not supported by the QEMU2 emulator on x86_64 host.

I'm on windows 10. How can I run an AVD with arm64 cpu architecture?

Answer 1

ARM64 emulation on a x86_64 host currently is only possible up to API level 27 Oreo:

#ifdef __x86_64__
  if (sarch == "arm64" && apiLevel >=28) {
      APANIC("Avd's CPU Architecture '%s' is not supported by the QEMU2 emulator on x86_64 host.\n", avdarch);
  }
#endif

You'd need an ARM64 CPU to run android-33:

#if defined(__aarch64__)
  if (sarch != "arm64") {
      APANIC("Avd's CPU Architecture '%s' is not supported by the QEMU2 emulator on aarch64 host.\n", avdarch);
  }
#endif

thanks martin, but I build my app with Delphi that produce native assembly :( – Haemoglobin

Using a hardware device might be the most reliable option for latest API on ARM64. MacBook M1 might eventually also be able to run the emulator; that's at least what the source code says. – Avis

thanks martin but do you know with hardware device I can found (except the macbook that is very expensive) to launch the emulator on arm ? – Haemoglobin

You're not launching anything on ARM, this is x86_64. Consumer grade hardware devices are much cheaper than a MacBook M1/M2; you'll have to invest about 200-300 EUR for that. I don't know why it's disabled for x86_64, but likely there is a god reason for it, which means a custom emulator won't help. – Avis

I have a pretty interesting behaviour. uname -p returning arm but when I trying to start emu with avd ``` INFO | Android emulator version 31.3.14.0 (build_id 9322596) (CL:N/A) emulator: INFO: Found systemPath /Users/tcagent/Library/Android/sdk/system-images/android-31/google_apis/arm64-v8a/ PANIC: Avd's CPU Architecture 'arm64' is not supported by the QEMU2 emulator on x86_64 host. ``` – Jew

Incredible that Android Studio does not warn you before hand or come with any understandable error when trying to launch Android 33 image! We have to open idea.log to find out AFTER installing an image that doesn't run. – Nabob

@AndersEmil I didn't even know you can see the error there, I had to run it from command line using this command to see the problem, google bad quality can never stop surprising to the worth: C:\Users\ronen\AppData\Local\Android\Sdk\emulator> .\emulator.exe -avd Automotive_1080p_landscape_API_33 -netspeed full -netdelay none – Downbeat

How am I supposed to develop to android auto if that's the only emulator they provide??? – Downbeat

@Jew I also got this same error on a Mac M3 trying to start an emulator with an ARM64 system image. It turned out the Android SDK Build Tools were too old for the system Java version. Updating the Build Tools in Android Studio's SDK Manager fixed it. Really misleading error message, thanks Google! – Decrypt
