Over the weekend, I started to work on my first Android app. I had a little trouble getting the Android emulator to run with HAXM, Intel's Hardware Accelerated Execution Manager, which builds on top of the virtualization hardware VT-x. Maybe others with the same problems find their way here...
These are the steps that worked for me - your mileage may vary. Read them carefully; I might have let my frustration slip into the steps at some point or other.
First check whether your processor actually supports virtualization.
- go to Intel
- find your processor
- check whether Intel® Virtualization Technology (VT-x) is listed under Advanced Technologies
- also read the footnote if there is one
Side note: VT-x is included in VT-d
▚Download HAXM installer
Now you can download the installer for the emulator accelerator.
- open the Android SDK Manager
- in Android Studio it's under Tools ~> Android ~> SDK Manager
- in Eclipse it's under Window ~> Android SDK Manager (look here if it's missing)
- check Intel x86 Emulator Accelerator (HAXM installer) under Extras and install packages
Next step is to actually install HAXM.
- above the package list the SDK manager shows the path to the SDK
- go there and then continue to ./extras/intel/Hardware_Accelerated_Execution_Manager
- run the intelhaxm-android installer
▚Fail In Different Ways (optional)
In case the installation doesn't work because the virtualization features are not turned on, there are several ways to waste some time...
- you can download intel's Processor Identification Utility (for Windows and Linux) and see it claim that Intel (R) Virtualization Technology is Yes (not my wording)
- you can install CPU-Z or i-Nex and watch it report VT-X (under instructions) to be turned on
After that small detour you might realize that the tools are lying to you...
- enter your BIOS (on my T440p: Enter on first boot screen, then F1)
- go to Config ~> CPU and be frustrated that it's not there...
- go to Security ~> Virtualization and turn everything on
- reboot and install successfully
