排查错误

执行avdmanager报错：java.lang.NoClassDefFoundError: javax/xml/bind/annotation/XmlSchema

原因我的arch linux 安装的 openjdk-15，安装了openjdk-8，用 archlinux-java set java-8-openjdk 切换为 java 8 就好了。

avd 启动报错：Qt library not found at ../emulator/lib64/qt/lib

1
emulator -avd Nexus7_API30_ARM

详细报错：

[140276254512960]:ERROR:android/android-emu/android/qt/qt_setup.cpp:28:Qt library not found at ../emulator/lib64/qt/lib
Could not launch '/home/wi/../emulator/qemu/linux-x86_64/qemu-system-aarch64': No such file or directory

解决方法：

可能使用的 emulator 不对，应该使用 SDK-HOME/emulator 目录下的 ，而不是 tools 目录下的。
