Android12编译x86模拟器报找不到userdata-qemu.img

Mr_Fingerling2025-04-16 8:12

qemu-system-x86_64: Could not open 'out/target/product/generic_x86_64/userdata-qemu.img': No such file or directory

选择编译aosp_x86-eng时没有生成模拟器，报

c 复制代码

qemu-system-x86_64: Could not open 'out/target/product/generic_x86_64/userdata-qemu.img': No such file or directory

这是因为编译"aosp_x86_64-eng"不会生成qemu所需镜像，需编译SDK版的。但在执行lunch时，只有car版的：

bash 复制代码

     64. sdk_car_arm-userdebug
     65. sdk_car_arm64-userdebug
     66. sdk_car_x86-userdebug
     67. sdk_car_x86_64-userdebug

需要自己添加phone版的选项，在build/make/target/product/AndroidProducts.mk中添加：

bash 复制代码

COMMON_LUNCH_CHOICES := \
    aosp_arm64-eng \
    aosp_arm-eng \
    aosp_x86_64-eng \
    aosp_x86-eng \
    sdk_x86_64-eng \
    sdk_phone_x86_64-eng \
    sdk_x86_64-userdebug \
    sdk_phone_x86_64-userdebug

再source build/envsetup.sh，再执行lunch就有了：

bash 复制代码

     64. sdk_car_arm-userdebug
     65. sdk_car_arm64-userdebug
     66. sdk_car_x86-userdebug
     67. sdk_car_x86_64-userdebug
     68. sdk_phone_x86_64-eng
     69. sdk_phone_x86_64-userdebug
     70. sdk_x86_64-eng
     71. sdk_x86_64-userdebug

选择70，编译完成，执行：

bash 复制代码

emulator

模拟器正常启动。
