In Android Studio V3.5, I created some AVDs which are based on Intel x86 CPU. But I failed to start any of them because any HAXM devices couldn't be found.

I have enabled VT-x in my BIOS setting. When I tried to install 'Intel Hardware Accelerated Execution Manager V7.0.5', it reported "failed to configure driver unknown error. failed to open driver.".

My PC is Windows 7 64-bit. I couldn't find any solutions.

So, is it possible to disable HAXM feature for an AVD based on Intel x86 CPU?

The Android emulator.exe has a lot of command-line options.

The one you need is -accel:

-accel <mode>

Valid values for mode are:
  auto - Determine automatically if acceleration is supported and use it when possible (default).
  off  - Disables acceleration entirely, which is primarily useful for debugging.
  on   - Force acceleration. If KVM or HAXM isn't installed or usable, the emulator won't > start and prints an error message.

Therefore you should use -accel off

  • Thank you sir. But in general, we start an AVD in the AVD Manager other than command line. In fact, I tried to find some option for this in myAVD.ini. But I failed to find any.
