我正在学习 AOSP 构建系统，尤其是如何添加新设备。
我在默认的全英配置上构建 android-6.0.1_r46 Marshmallo 并在模拟器上运行它。它工作正常。
但是，当我尝试在/device/my_company/my_product/之类的源树中添加我的自定义设备而不是成功构建并在模拟器上运行它时 - 模拟器只是挂断了黑屏。根本不加载。
我怎样才能让模拟器工作？
我的makefile如下所示..
安卓.mk

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
include $(call all-makefiles-under,$(LOCAL_PATH))

最佳答案
您正在构建一个无法在 qemu 上模拟的 arm 设备。
您可以尝试为任何预先存在的设备(如珊瑚或梅林)构建并检查它是否为它们启动。但可能不会。
关于android - AOSP 基于自定义设备 - 模拟器构建，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/49492965/
