ARM64 Chromebook无Android Studio装Android SDK遇XML解析及包查找问题

在ARM64架构的Chromebook上，不通过Android Studio安装Android SDK时，执行sdkmanager命令遇到以下异常：

执行sdkmanager --update的输出 #

$ sdkmanager --update
Warning: Errors during XML parse:                                               
Warning: Additionally, the fallback loader failed to parse the XML.

• 修复XML配置文件：删除~/.android/repositories.cfg（若存在），重新运行sdkmanager，系统会自动生成新的配置文件，解决XML解析错误。
• 安装ARM64架构的模拟器包：直接指定ARM64版本的完整包名安装，比如：sdkmanager --install "emulator;33.1.22"（版本号可通过sdkmanager --list查看最新可用项）。
• 强制更新SDK管理器：添加--no_https参数绕过HTTPS验证尝试更新：sdkmanager --update --no_https，或手动替换最新的sdkmanager工具文件。
• 检查环境变量：确认ANDROID_HOME指向SDK安装目录，且PATH包含SDK的tools和platform-tools子目录。
