构建AOSP时找不到sdk_phone_x86_64启动组合的问题求助

我在Ubuntu机器上构建AOSP并尝试模拟，按照官方文档执行了以下克隆命令：

repo init -u https://android.googlesource.com/platform/manifest
repo sync -c -j31
source build/env_setup.sh

克隆完成后，找不到官方模拟器指南里指定的sdk_phone_x86_64启动组合，运行lunch后显示的是一系列陌生的组合：

输入命令launch sdk_phone_x86_64-userdebug时，系统返回错误：Invalid launch combo: launch sdk_phone_x86。想问是不是克隆仓库时漏了步骤？

问题出在你克隆的是AOSP的trunk_staging开发预览分支——从lunch选项里的-trunk_staging-后缀就能看出来。这个分支已经替换了旧的sdk_phone_x86_64目标，改用CF（Cloud Foundation）系列的新目标。

你有两种解决办法：

办法一：切换到稳定分支 #

不需要重新克隆仓库，直接切换到对应稳定版本的分支即可，以Android 14稳定分支为例：

1. 重置manifest到稳定分支：

repo init -u https://android.googlesource.com/platform/manifest -b android-14.0.0_r50

2. 重新同步代码：

repo sync -c -j31

3. 重新初始化构建环境：

source build/env_setup.sh

之后运行lunch就能找到官方文档里的sdk_phone_x86_64-userdebug选项。

办法二：使用当前分支的替代目标 #

如果不想切换分支，直接选择列表里的第16项aosp_cf_x86_64_phone-trunk_staging-userdebug即可，这个就是sdk_phone_x86_64的替代版本，完全适配模拟器运行。
