Android模拟器:从AOSP构建boot.img [英] Android emulator: Building boot.img from AOSP

问题描述

我正在尝试在Debian 7(amd64)上构建AOSP 4.3(内部版本:JSR78D；分支:android-4.3_r2).我遵循了 Google Android网站中列出的说明，并成功完成了构建步骤.最后，我可以使用 Android模拟器测试我新建的图像.

I am trying to build AOSP 4.3 (build: JSR78D; branch: android-4.3_r2) on Debian 7 (amd64). I followed the instructions listed in Google Android website and finished build steps successfully. At the end, I could test my newly built image with the Android emulator.

现在，我在out/target/product/generic目录中有3个图像文件:system.img，userdata.img和ramdisk.img.但是，缺少boot.img.我尝试发出make bootimage命令，但是它无助于生成上述文件.我希望Makefile为我自动构建此文件，因为它包含build/core/main.mk，其中bootimage作为其目标之一.

Now, I have 3 image files in the out/target/product/generic directory: system.img, userdata.img, and ramdisk.img. However, boot.img is missing. I tried issuing the make bootimage command, but it did not help generating the aforesaid file. I expected Makefile to automatically build this file for me since it includes build/core/main.mk which has bootimage as one of its targets.

PS.我见过类似 this 的帖子，但目前尚不清楚我为什么boot.img不能自动构建.

PS. I have seen posts like this, but it is still not clear to me why boot.img is not built automatically.

推荐答案

Boot.img包含内核.这是操作系统和硬件之间的接口.仿真器设备中没有硬件.(通用).

Boot.img contains the kernel. Which is the interface between the OS and the hardware. We don't have hardware in emulator device.(generic).

您要boot.img吗?为真实设备(例如Nexus 5)构建Android

You want boot.img? build Android for a real device(Ex. Nexus 5)
