使用自定義構建內核運行Android Emulator

Question

我嘗試從Ubuntu 16.04使用自定義構建內核運行android模擬器。 構建內核的步驟：

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，當我嘗試使用此映像運行模擬器時：

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

模擬器窗口啟動，我看到“ Android”徽標，但沒有其他反應。 它是bootloop，在控制台中，我一次又一次看到此消息：

[   22.396836] init: Starting service 'netd'... 
[   22.397460] init: Starting service 'media'... 
[   22.397919] init: Starting service 'zygote'...

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

但是我不想構建ASOP並添加對thread.cc的修復，因為我只需要來自Google的自定義內核和官方映像。

我如何構建內核來避免此錯誤，或者在運行模擬器時可能是某些選擇？

PS我還嘗試了另一個金魚分支（android-goldfish-3.10），但結果相同。

謝謝您的回答！

Answer 1

我有同樣的問題，我切換到分支“ origin / android-goldfish-3.10-n-dev”，使用Android 7.0 x86_64映像，模擬器運行良好。

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