Could not open avd_name.avd/cache.img

Question

When i run emulator, i get the following error:

Cannot launch AVD in emulator.

Output: Hax is enabled qemu-system-x86_64.exe: -drive if=none,index=1,id=cache,file={path_to_SDK}\SDK.android\avd{AVD_name}.avd/cache.img: could not open disk image {path_to_SDK}\SDK.android\avd{AVD_name}.avd/cache.img:

Could not open '{path_to_SDK}\SDK.android\avd{AVD_name}.avd/cache.img':

Invalid argument

Hax ram_size 0x40000000

HAX is working and emulator runs in fast virt mode. Error accepting connection, aborting

AVD specs are:

OS: Android 6.0 Google APIs

RAM: 1GB

Resolution: 1440x2560

Running on Android Studio 2.0 Beta 6, Windows 10.

i think there is some issue with image file – Vivek Mishra Feb 29 '16 at 13:48 — Vivek Mishra, Feb 29 '16 at 13:48

Keep an eye out for a background qemu-system-i386.exe process running in the background that will be locking the cache.img file.

Windows Task Manager - Background Emulator Process

This might be still running from a previously failed emulator launch. Kill that using Task Manager and start again.

Had this issue in Visual Studio and killing this task (no emulators showed to be running) and restarting debug took care of the error. – Robb Sadler Dec 13 '16 at 22:42

When you look at the answers / comments for questios like this... a native .net developer wonders if they can ever reliably count on microshaft. – Kulingar Jan 08 '17 at 21:44

I had the same problem already twice since I upgraded to Android Studio 2.0 on Windows 10. I use a preferred emulator in the Run/Debug configuration. Changing the Deployment Target Options in the configuration to Target: Show Device Chooser Dialog solved it for me. After choosing the same emulator instance in the dialog it started with no problem. Then I change back to the preferred emulator setting. Until the next time it breaks...

Hoping this helps.

How do you do the equivalent from Visual Studio? – James John McGuire 'Jahmic' Sep 29 '16 at 04:37 — James John McGuire 'Jahmic', Sep 29 '16 at 04:37

I faced the same problem in Windows 10.

Clearing temp and %temp% folder followed by a restart of machine solved my problem.

I had this problem, when I didn't notice that emulator is already running :)
