android.bp 宏

一、区别

二、mk转换为bp

三、宏变量对应关系

四、常用宏变量作用

一、区别

Android.bp --> Soong --> Ninja
Makefile or Android.mk --> kati --> Ninja

最终都是生成Ninja格式文件进行编译。

二、mk转换为bp

Android.bp的出现就是为了替换Android.mk文件。bp跟mk文件不同，它是纯粹的配置，没有分支、循环等流程控制，不能做算数逻辑运算。如果需要控制逻辑，那么只能通过Go语言编写。旧的mk可以转换为bp，Soong会编译生成一个androidmk命令，用于将Android.mk文件转换为Android.bp文件。只针对简单的mk文件转换，涉及分支，循环等控制转换并不准确。即：

Android.mk --> Soong中androidmk --> Android.bp

三、宏变量对应关系

直接在"build/soong/androidmk/androidmk/android.go"文件中找：

四、常用宏变量作用

不断更新...记录常用但不好理解的

LOCAL_PROPRIETARY_MODULE，proprietary：true控制生成路径到vendor/lib，false就是system/lib;
LOCAL_CLANG，clang：true来指定默认编译器为Clang，Android 8.0后不需要指定，默认是Clang；
-----------------------------------------------------alibli分割符-------------------------------------------------------
LOCAL_SRC_FILES：当前模块包含的所有源代码文件
LOCAL_MODULE：当前模块的名称，这个名称应当是唯一的，模块间的依赖关系就是通过这个名称来引用的
LOCAL_C_INCLUDES：C 或 C++ 语言需要的头文件的路径
LOCAL_STATIC_LIBRARIES：当前模块在静态链接时需要的库的名称
LOCAL_SHARED_LIBRARIES：当前模块在运行时依赖的动态库的名称
LOCAL_CFLAGS：提供给 C/C++ 编译器的额外编译参数
LOCAL_JAVA_LIBRARIES：当前模块依赖的 Java 共享库
LOCAL_STATIC_JAVA_LIBRARIES：当前模块依赖的 Java 静态库
LOCAL_PACKAGE_NAME：当前 APK 应用的名称
LOCAL_CERTIFICATE：签署当前应用的证书名称
LOCAL_MODULE_PATH：指定输出路径
LOCAL_PRIVILEGED_MODULE：指定生成的apk是否在system/priv-app/下，等同于设置LOCAL_MODULE_PATH := $(TARGET_OUT)/system/priv-app
LOCAL_MODULE_TAGS：user/debug/eng/optional 指定该模块在什么版本下编译 optional 表示所有版本都编译
-----------------------------------------------------alibli分割符-------------------------------------------------------
BUILD_HOST_STATIC_LIBRARY：编译静态库（适用于主机）
BUILD_HOST_SHARED_LIBRARY：编译动态库（适用于主机）
BUILD_HOST_EXECUTABLE：编译可执行程序(适用于主机)
BUILD_HOST_PREBUILT：预编译(适用于主机)
BUILD_HOST_JAVA_LIBRARY：编译java包(适用于主机)
BUILD_JAVA_LIBRARY：编译java包
BUILD_STATIC_JAVA_LIBRARY：编译java静态包
BUILD_STATIC_LIBRARY：编译静态库
BUILD_SHARED_LIBRARY：编译动态库
BUILD_EXECUTABLE：编译可执行程序
BUILD_PACKAGE：编译apk
BUILD_PREBUILT：预编译(针对单个预编译文件)
BUILD_MULTI_PREBUILT：预编译(针对多个预编译文件)
-----------------------------------------------------alibli分割符-------------------------------------------------------

LOCAL_SHARED_LIBRARIES、LOCAL_LDLIBS、LOCAL_LDFLAGS的区别：

LOCAL_SHARED_LIBRARIES 会生成依赖关系，当库不存在时会去编译这个库。

LOCAL_LDLIBS ：链接的库不产生依赖关系，一般用于不需要重新编译的库，如库不存在，则会报错找不到。且貌似只能链接那些存在于系统目录下本模块需要连接的库。如果某一个库既有动态库又有静态库，那么在默认情况下是链接的动态库而非静态库。

如：LOCAL_LDLIBS += -lm –lz –lc -lcutils –lutils –llog …

如果你的Android.mk文件中只有这么一行，那么将会采用动态链接。

LOCAL_LDFLAGS：这个编译变量传递给链接器一个一些额外的参数，比如想传递额外的库和库路径给ld，或者传递给ld linker的一些链接参数，-On，-EL{B}(大小端字节序)，那么就要加到这个上面，如：

LOCAL_LDFLAGS += -L$(LOCAL_PATH)/lib/ -lHWrecog –EB{EL} –O{n} …

或者直接加上绝对路径库的全名：

LOCAL_LDFLAGS += $(LOCAL_PATH)/lib/libHWrecog.a –EB{EL} –O{n}

如果是非系统的第三方库，貌似只能用LOCAL_LDFLAGS方式，LOCAL_LDLIBS方式不行。
