Linux is not perfect to improve the startup speed of Android virtual machine __linux

Last year double A new computer, Asus vivo4000, configuration is not very good, 4k screen: 3840x2160, 940M graphics card, Core i7 CPU, 8G of memory, hard drive is 1T mechanical hard drive, in addition to the basic sense of hard disk can be. The system is WIN10 home version, a bit uncomfortable, and later redistribution of their own hard disk partition, installed my favorite Manjaro Linux, almost every day update. Linux is not a bit more cool than WINDOW10. Ha ha. Okay, here we go. Roman:

(1) Core i7 support VT Technology, many online tutorials are installed under Windows HAXM Drive, and then to the Intel official website, found that there is a window version of the Mac version of Linux, Linux has been enabled by default

(2) After more than n verification, it is found that the virtual machine startup will be in the/home/xxxxx/.android/avd/(virtual machine directory) to create a directory, the name is metrics, if there is no file in this directory and its directory, start normal

(3) My solution is to start the virtual machine after removing the directory every time the virtual machine is started. Fast, up to 20s to start.

(4) One drawback of this solution is that each time you want to delete a directory and start the Android virtual machine in the android/tools/directory, my solution is to add the android/tools/directory to the/etc/profile file. So the document reads as follows: Path= ".:/ usr/local/sbin:/usr/local/bin:/usr/bin:/home/michelle/workm/android_sdk/tools/", note that there is a". "At the front. The directory means the current directory. Using commands: Emulator64-x86-avd nbandroidvm-qemu-m 2047-ENABLE-KVM, this command is a bit more complicated, say: emulator64-x86 the command to start the virtual machine-AVD NBANDROIDVM Option followed by the name of the virtual machine-qemu boot acceleration-m 2047 specifies that the memory is 2047 and cannot be set to 2048, otherwise it will not start-ENABLE-KVM the last one is a virtual technology using Linux, and then simply bang: Write a script that reads as follows:

#!/bin/bash
rm-rf/home/michelle/.android/avd/metrics/
echo "Delete directory succeeded"
EMULATOR64-X86-AVD nbandroidvm-qemu-m 2047-ENABLE-KVM

You can save the above 4 lines in a startavd.sh script file, chmod +x startavd.sh, add the script to the executable property, then double-click the script to start the virtual machine, or use SH startavd.sh to start the virtual machine.

(5) In order to secure the period, the cancellation, you can enjoy the feeling of flying general.
