This can happen due to a couple of problems. HAXM problems often occur because of Intel chipsets. The Intel Hardware Accelerated Execution Manager (Intel? HAXM) is a hardware-assisted virtualization engine (hypervisor) that uses Intel Virtualization Technology (Intel? VT) to speed up Android app emulation on a host machine. In combination with Android x86 emulator images provided by Intel and the official Android SDK Manager, HAXM allows for faster Android emulation on Intel VT-enabled systems:
