Android.mk 中覆盖应用包名

项目场景：

一般来讲应用包名都是配置在 AndroidManifest.xml 中的，但遇到特殊情况，需要修改源码中应用包名

通常都会先去改 AndroidManifest.xml package 但改为后编译发现一顿错误，原因是 java 类中已经指定了 R 文件包名，

几百个都去替换那岂不是一堆文件需要 add，所以想找找有没有快捷方法，还真被我找到了。

解决方案：

通过配置 LOCAL_AAPT_FLAGS := rename-manifest-package "com.android.camera" 就可以

毕竟在 AS 中通过 gradle 配置 applicationId 就可以修改包名，想来 mk 中也是有的，不常用而已。

一开始发现 mk 中可以修改应用的版本号，那么猜测是不是也可以修改包名。

LOCAL_AAPT_FLAGS := --version-name "$(version_name_package)"
LOCAL_AAPT_FLAGS := --version-code "$(version_code_package)"

通过以上配置可以修改应用版本号，我就顺手配了个 LOCAL_AAPT_FLAGS := --package “com.android.camera”

编译小试一下，报错提示如下

–static-lib is specified.
–no-proguard-location-reference Keep proguard rules files from having a reference to the source file
–stable-ids arg File containing a list of name to ID mapping.
–emit-ids arg Emit a file at the given path with a list of name to ID mappings,
suitable for use with --stable-ids.
–private-symbols arg Package name to use when generating R.java for private symbols.
If not specified, public and private symbols will use the application’s
package name.

–add-javadoc-annotation arg Adds a JavaDoc annotation to all generated Java classes.
–output-text-symbols arg Generates a text file containing the resource symbols of the R class in
the specified folder.
–allow-reserved-package-id Allows the use of a reserved package ID. This should on be used for
packages with a pre-O min-sdk

–auto-add-overlay Allows the addition of new resources in overlays without
tags.
–override-styles-instead-of-overlaying Causes styles defined in -R resources to replace previous definitions
instead of merging into them

–rename-manifest-package arg Renames the package in AndroidManifest.xml.
–rename-resources-package arg Renames the package in resources table
–rename-instrumentation-target-package arg Changes the name of the target package for instrumentation. Most useful
when used in conjunction with --rename-manifest-package.
–rename-overlay-target-package arg Changes the name of the target package for overlay. Most useful
when used in conjunction with --rename-manifest-package.
-0 arg File suffix not to compress.
–no-compress Do not compress any resources.
–keep-raw-values Preserve raw attribute values in xml files.
–no-compress-regex arg Do not compress extensions matching the regular expression. Remember to
