Android.mk总结
Android源码编译不同的版本,略微有不同
4.4 采用圝的方式
9.0使用圝的方式
编写app之前,确认编译环境使用的sdk版本,在build.gradle中配置成一样的
删掉不需要用的东西,也许某个虚线下面在编译时就是一个炸弹
一个apk构依赖部分
系统属性/自己项目的module/第三方jar/第三方aar/so库
-
系统预编译好的属性
如AndroidX系列,
implementation 'androidx.constraintlayout:constraintlayout:1.1.0
可在编译目录中通过查找对应 name属性find prebuilts/sdk/ -name Android.bp|xargs grep "name.*constraintlayout"
mk如下:
LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_USE_AAPT2 := true
...
LOCAL_STATIC_ANDROID_LIBRARIES := \ androidx-constraintlayout_constraintlayout
include $(BUILD_PACKAGE)
-
依赖自己项目中Module
1.只依赖java文件,即常用的jar包
module中配置Android.bp
java_library {
name: "constantproxy",
srcs: [
"src/main/java/**/*.java",
],
exclude_srcs: [
],
libs: [
],
static_libs: [
"androidx.media_media", //依赖的系统属性
],
required: [
],
dxflags: [
],
}
app中Android.mk
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_USE_AAPT2 := true
...
LOCAL_STATIC_JAVA_LIBRARIES := \
constantproxy\
2.既依赖java又依赖res
此种module不需要写mk
在app中引入即可
? 理论上是不是每个module都可以这么写
LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_USE_AAPT2 := true
LOCAL_MODULE_TAGS := optional
LOCAL_SRC_FILES := $(call all-java-files-under, src)
LOCAL_SRC_FILES += $(call all-java-files-under, yourmodule/src)
LOCAL_RESOURCE_DIR += $(LOCAL_PATH)/src/main/res
LOCAL_RESOURCE_DIR += $(LOCAL_PATH)/yourmodule/src/main/res
#注意yourmodule路径的准确性
LOCAL_AAPT_FLAGS := --auto-add-overlay \
--extra-packages yourmodule包名 \
...
include $(BUILD_PACKAGE)
-
第三方jar
在jar的同级目录下新建Androd.bp 如libs/Android.bp
java_import {
name: "my_jar",
jars: ["annotation-1.1.0.jar"],
}
如果依赖第三方jar的是库,则在库里面的Android.bp中
java_library {
name: "my_lib_core",
srcs: [
"src/main/java/**/*.java",
],
exclude_srcs: [
],
libs: [
],
static_libs: [
"androidx.appcompat_appcompat","my_jar"
],
required: [
],
dxflags: [
],
}
如果是自己的项目,则在app中Android.mk
LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_USE_AAPT2 := true
LOCAL_STATIC_JAVA_LIBRARIES := \
my_jar \
...
LOCAL_PRIVATE_PLATFORM_APIS := true
include $(BUILD_PACKAGE)
-
依赖第三方aar
在aar同级目录Android.bp中
android_library_import {
name: "navigation-fragment-nodeps",
aars: ["libs/navigation-fragment-2.3.0-alpha01.aar"],
sdk_version: "current",
static_libs: [
"androidx.fragment_fragment", //navigation-fragment依赖androidx.fragment_fragment
],
}
android_library {
name: "androidx.navigation_navigation-fragment",
sdk_version: "current",
manifest: "androidx.navigation.fragment/AndroidManifest.xml",
static_libs: [
"navigation-fragment-nodeps",
"androidx.fragment_fragment",
],
java_version: "1.8",
}
在Android.mk中
LOCAL_STATIC_ANDROID_LIBRARIES := \
androidx.navigation_navigation-fragment
-
so库
此so库指的是NDK编译出来的so库,libs下直接可用
需要用到so库的mk里面
include $(BUILD_PACKAGE)
libs_dir := $(TARGET_OUT)/app/yourapkname/lib/armeabi
$(shell mkdir -p $(libs_dir))
src_files := $(shell ls $(LOCAL_PATH)/libs/armeabi/)
$(foreach file, $(src_files),\
$(shell cp $(LOCAL_PATH)/libs/armeabi/$(file) $(libs_dir)/$(file)))
Android9.0源码中的mk例子
LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_USE_AAPT2 := true
LOCAL_PACKAGE_NAME := APK名字
LOCAL_OVERRIDES_PACKAGES :=
LOCAL_MODULE_TAGS := optional
# can't use LOCAL_SDK_VERSION, otherwise the error will occur like this:
# "(java:sdk) should not link to"
#LOCAL_SDK_VERSION := current
LOCAL_PRIVATE_PLATFORM_APIS := true
LOCAL_PRIVILEGED_MODULE := true
LOCAL_JAVACFLAGS := -Xlint:deprecation -Xlint:unchecked
#LOCAL_PROGUARD_FLAG_FILES := proguard.flags
