Android 单独编译 hal 中的模块

在android hal层添加了自己需要的模块，模块添加可以直接参考下android hardware目录下的代码 依葫芦画瓢 添加就OK。

但是编译不能在用全局编译了，

可以采用如下方式：

source ./build/envsetup.sh

choosecombo

Build for the simulator or the device?
1. Device
2. Simulator

Which would you like? [1]//选择Device

Build type choices are:
1. release
2. debug

Which would you like? [1]//选择release

Which product would you like? [OK6410]//填写自己平台名称

 

Variant choices are:
1. user
2. userdebug
3. eng
Which would you like? [eng] //选eng

然后就可以

直接make 模块了，例如要编译 led模块 就可以这样做

make led

// 注意“led”是hal层定义led的名称，这个可以从相应目录下Android.mk文件中查询

例如我的led模块定义如下：

LOCAL_MODULE:= led
