Android P以下版本导入PRODUCT_BOOT_JARS

增加package白名单
源码文件build/make/core/tasks/check_boot_jars/package_allowed_list.txt增加jar包名白名单

#e.g. com.king.test.module-dex.jar
com\.king\.test
com\.king\.test\..*
编写jar包Android.mk文件(此jar包为dex文件)
LOCAL_PATH := $(call my-dir)
#e.g. com.king.test.module-dex.jar
include $(CLEAR_VARS)
LOCAL_MODULE := com.king.test.module
LOCAL_MODULE_TAGS := optional
LOCAL_SRC_FILES := com.king.test.module-dex.jar
LOCAL_MODULE_SUFFIX := $(COMMON_JAVA_PACKAGE_SUFFIX)
LOCAL_MODULE_CLASS := JAVA_LIBRARIES

make编译
$make –j8
Android 11 版本导入PRODUCT_BOOT_JARS
编写jar包Android.bp文件(此jar包为class文件)
使用androidmk命令把Android.mk文件生成Android.bp
$androidmk Android.mk > Android.bp
生成后的文件如下:
java_import {
name: "com.king.test.module",
jars: ["com.king.test.module-class.jar"],
}
Android.bp增加java_library
如上Android.bp文件会编译报错:
internal error: failed to find a dex jar path for module ’ com.king.test.module’, note that some jars may be filtered out by module constraints
增加java_library定义,installable 为 true ,否则会同样错误,如下:
java_import {
name: "com.king.test.module_jar",
jars: ["com.king.test.module-class.jar"],
}
java_library {
name: "com.king.test.module",
static_libs: [
" com.king.test.module_jar",
],
installable: true,
}
jar包为dex文件编译运行出错处理
如果jar包是已经编译好的dex文件而不是纯class文件,在Android11上编译会有以下问题,处理方式可参见说明
check_boot_jars.py 检查出错
Error: out/target/common/obj/JAVA_LIBRARIES/ com.king.test.module_intermediates/classes.jar does not contain any class files.
解决方法: 修改build/make/core/tasks/check_boot_jars/check_boot_jars.py,注释"if classes == 0"的判断
也可java_library 增加空的java文件,如下
// srcs: [
// "src/**/*.java",
// ],
不过此方法会后面编译出错:
Error: Cannot create android app from an archive ‘out/soong/.intermediates/vendor/king/ com.king.test.module/android_common/combined/com.king.test.module.jar’ containing both DEX and Java-bytecode content
merge_zips合并jar包出错
merge_zips.go:752: Duplicate path classes.dex found in out/soong/.intermediates/vendor/king/com.king.test.module/android_common/dex/classes.dex.jar!classes.dex and out/soong/.intermediates/vendor/king/com.king.test.module_jar/android_common/combined/com.king.test.module_jar.jar
解决方法: 修改build/soong/cmd/merge_zips/merge_zips.go,修改参数ignore-duplicates为true
