android bp脚本
一。android大约从7.0开始引入 .bp文件代替以前的.mk文件，用于帮助android项目的编译配置文件。
二。mk文件转化为bp文件，可以使用下面命令转化，注意命令中>，这是写入文件。androidmk是android源码自带的工具，他可以显示mk转换后的bp，后面是写入Android.bp
androidmk Android.mk > Android.bp
三。这两个编译脚本可以对应，所以能够转化，可以在下面的文件中看到对应的规则，事实是，虽然使用了bp，但mk依然可以正常使用，如果有老项目，可以不必转化
/build/soong/androidmk/cmd/androidmk/android.go
四。bp编译脚本常用的模块关键字
1.编译成 Java 库
java_library
2.编译成 Java 静态库
java_library_static
3.编译成 App 应用
Android.bp
android_app {
......
}
4编译成 Native 动态库
Android.bp
cc_library_shared {
......
}
5 编译成 Native 静态库
Android.bp
cc_library_static {
......
}
6 编译成 Native 执行程序
Android.bp
cc_binary {
......
}
7 编译成头文件库
Android.bp
cc_library_headers {
......
}
8 预加载静态库
cc_prebuilt_library_static
9 预加载动态库
cc_prebuilt_library
五文件路径
1 本地头文件路径
Android.bp
local_include_dirs: ["xxx", ...]
2 导出的头文件路径
Android.bp
export_include_dirs: ["xxx", ...]
3 资源文件路径
Android.bp
resource_dirs: ["xxx", ...]
六 库依赖
1 依赖的静态库
Android.bp
static_libs: ["xxx", "xxx", ...]
2 依赖的动态库
Android.bp
shared_libs: ["xxx", "xxx", ...]
3 依赖的头文件库
Android.bp
header_libs: ["xxx", "xxx", ...]
4 依赖的 Java 库
Android.bp
static_libs: ["xxx", "xxx", ...]
七安装到不同分区中
1 安装到vendor中
Android.bp
proprietary: true
or
vendor: true
2 安装到product中
Android.bp
product_specific: true
3 安装到odm中
Android.bp
device_specific: true
八编译参数
1 C flags
Android.bp
cflags: ["xxx", "xxx", ...]
2 Cpp flags
Android.bp
cppflags: ["xxx", "xxx", ...]
3 Java flags
Android.bp
javacflags: ["xxx", "xxx", ...]
九一个放置第三方open ssl so和a的bp
cc_prebuilt_library_static {
name: "liboopenssl",
//product_available: true,
//vendor_available: true,
//vndk: {
// enabled: true,
//},
srcs: [
"lib/libssl.a",
],
export_include_dirs: ["include"],
//vendor: true
}
cc_prebuilt_library {
name: "libopenssl_shared",
product_available: true,
vendor_available: true,
vndk: {
enabled: true,
},
srcs: [
"lib/libssl.so",
],
shared_libs: [
],
//sanitize: {
// never: true,
//},
static_libs: [
//"liboopenssl",
],
export_include_dirs: ["include"],
//vendor: true
}
cc_prebuilt_library_static {
name: "liboopencrypto",
//product_available: true,
//vendor_available: true,
//vndk: {
// enabled: true,
//},
srcs: [
"lib/libcrypto.a",
],
export_include_dirs: ["include"],
//vendor: true
}
cc_prebuilt_library {
name: "libopencrypto_shared",
product_available: true,
vendor_available: true,
vndk: {
enabled: true,
},
srcs: [
"lib/libcrypto.so",
],
shared_libs: [
],
//sanitize: {
// never: true,
//},
static_libs: [
//"liboopencrypto",
],
export_include_dirs: ["include"],
//vendor: true
}
十。C++ aidl生成
cc_library_static{
name:"libaidltest",
local_include_dirs:[
"include"
],
aidl:{
local_include_dirs:["aidl"],
include_dirs:[
"frameworks/native/aidl/binder"
],
export_aidl_headers:true,
},
srcs:[
"FileInfo.cpp",
":libfile_aidl"
],
shared_libs:[
"libbinder",
"libutils",
],
}
filegroup{
name:"libfile_aidl",
srcs:[
"aidl/com/hht/FileInfo.aidl",
"aidl/com/hht/IFileInfoCallback.aidl",
"aidl/com/hht/IGetFileInfo.aidl"
],
path:"aidl",
}
十二
// 生成一个so库
cc_library_static {
name: "libfileservice_aidl",
srcs: [
":fileservice_aidl",
],
aidl: {
local_include_dirs: ["aidl"],
include_dirs: [
"frameworks/native/aidl/binder"
],
export_aidl_headers: true,
},
shared_libs: [
"libbinder",
"libutils",
"liblog",
],
}
filegroup {
name: "fileservice_aidl",
srcs: [
"aidl/com/filetool/IFileOperation.aidl",
],
path:"aidl",
}
//
// 生成可执行文件
cc_binary {
name: "fileservice",
srcs: [
"main.cpp",
"FileService.cpp",
],
init_rc: ["sota.rc"],
cflags: [
"-Werror",
"-Wno-error=deprecated-declarations",
"-Wall",
"-Wformat-security",
"-Wno-unused-parameter",
],
shared_libs: [
"libbinder",
"libcutils",
"liblog",
"libutils",
"libbase",
],
static_libs:[
"libfileservice_aidl",
]
}
