I\'ll find lot\'s of solution in SO or in google but it\'s can\'t help full for me
Whenever i\'ll start AVD then below error can show me :
1 : Uninstall HAXM in Control Panel
2 : Uncheck Intel x86 Emulator Accelerator (Haxm installer) in SDK Manager -> SDK Tools then Click OK
3 : Download haxm v7_5_6.zip in this link and extract it
4 : Before Install it, restart your PC and go to Advanced Boot Options by pressing F8
5 : Select Disable Driver Signature Enforcement
6 : Install intelhaxm-android.exe from extracted zip, wait until installation completed and should be no error with all of this step.
Hope this help
