android emulator 命令的一些问题

在 ubuntu 20 系统中

• android emulator 命令的位置在 $ANDROID_SDK_HOME/emulator 目录下

• android studio 创建的 avd 存放在 ～/.android/avd 目录下

• 如果已经在Android Studio 中创建了avd，但是执行 ./emulator -list-avds 如果找不到任何 avd，可以将配置一下，在 ～/.bashrc 中添加一行

export ANDROID_AVD_HOME="/home/sunzy/.android/avd/"

• 目前好像真的不能运行 arm 架构的 avd，这个目前还没有找到好的办法

sunzy@sunzy:~/soft/usoft/Android_sdk_linux/Sdk/emulator$ ./emulator -avd Pixel_2_API_31
INFO    | Android emulator version 31.2.8.0 (build_id 8143646) (CL:N/A)
PANIC: Avd's CPU Architecture 'arm64' is not supported by the QEMU2 emulator on x86_64 host.

大家有好的解决办法可以cue我

• failed to initialize KVM: Device or resource busy 解决办法

你是否同时在用VirtualBox，关闭 VirtualBox
