Question

我尝试使用Ubuntu 16.04中的自定义构建内核运行android模拟器。构建内核的步骤：

git clone https://android.googlesource.com/kernel/goldfish/ -b android-goldfish-3.18
git clone https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/x86/x86_64-linux-android-4.9
cd goldfish
export CROSS_COMPILE=x86_64-linux-android-
export ARCH=x86_64
export PATH=$PATH:/path/to/x86_64-linux-android-4.9/bin
make x86_64_ranchu_defconfig
make -j4

然后，当我尝试使用此图像运行模拟器时：

emulator -avd Nexus_5_API_24 -kernel /path/to/goldfish/arch/x86/boot/bzImage -show-kernel

模拟器窗口启动，我看到＆＃34; Android＆＃34;徽标，但没有其他事情发生。它是bootloop，在控制台中我一次又一次地看到这条消息：

[   22.396836] init: Starting service 'netd'... 
[   22.397460] init: Starting service 'media'...

我在这里找到了一些答案： https://gist.github.com/yan12125/78a9004acb1bed5faf2ffd442163e2ef

但我不想构建ASOP并为thread.cc添加修复程序，因为我只需要来自Google的自定义内核和官方图片。

如何构建内核以避免此错误，或者，运行模拟器时可能是一些选项？

P.S。我还尝试了另一个金鱼分支（android-goldfish-3.10），但结果相同。

感谢您的回答！

我有同样的问题，我切换到分支＆＃34; origin / android-goldfish-3.10-n-dev＆＃34;，使用Android 7.0 x86_64图像，模拟器效果很好。

cd goldfish
git checkout -b mybranch origin/android-goldfish-3.10-n-dev

使用自定义构建内核
