我正在学习AOSP构建系统，特别是如何添加新设备 我在默认的full-eng配置上构建android-6.0.1_r46 Marshmallo并在模拟器上运行它。它运作正常。
但是当我尝试在/ tree / my_company / my_product /之类的源代码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时 - 模拟器只是挂起黑屏。根本没有加载。
我如何让模拟器工作？ 我的makefile如下所示..
Android.mk

include $(CLEAR_VARS)

您正在为无法在qemu上仿真的手臂设备而构建。 您可以尝试为任何现有的设备（例如珊瑚或梅林）构建并检查其是否为它们启动。但可能不会。
