Android 如何在 AOSP 版本中添加 APK？

How do I add APKs in an AOSP build?

提问by CodeGuru

I need to add some 3rd party APKs to my AOSP build. What folder should I keep these APKs so that when I build the code and the image is created, it is installed in the emulator?

我需要在我的 AOSP 构建中添加一些 3rd 方 APK。我应该将这些 APK 保存在哪个文件夹中，以便在构建代码和创建图像时将其安装在模拟器中？

It looks like the system apps are kept in the packages/appfolder so I need to know where the third party APKs are kept.

看起来系统应用程序保存在包/应用程序文件夹中，所以我需要知道第三方 APK 的保存位置。

Adding third party APKs to the build is definitely possible.

将第三方 APK 添加到构建中绝对是可能的。

Also APKs and APPs with source code go to the same place; the package/appfolder.

也有源代码的 APK 和 APP 去同一个地方；该package/app文件夹。

Adding a new APK to the build

将新的 APK 添加到构建中

In the AOSP root add the folder:

在 AOSP 根目录中添加文件夹：

<aosp root>/package/app/< yourappfolder >

<aosp root>/package/app/< yourappfolder >

Then inside this folder add:

然后在这个文件夹中添加：

• empty Android.mk
• < yourapp.apk >

• 空的 Android.mk
• < yourapp.apk >

The android make file should have the reference to your apk, add this to your Android.mk:

android make 文件应该包含对您的 apk 的引用，将其添加到您的Android.mk：

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE_TAGS := optional

LOCAL_MODULE := < your app folder name >

LOCAL_CERTIFICATE := < desired key >

LOCAL_SRC_FILES := < app apk filename >

LOCAL_MODULE_CLASS := APPS

LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX)

include $(BUILD_PREBUILT)

Create an entry in the commons.mk(from AOSP 8.1.0 onwards it is called core.mk, and is usually found in build/target/product) for your apk add the line (check where all the others are)

在您的 apk 中创建一个条目commons.mk（从 AOSP 8.1.0 开始，它被称为core.mk，通常可以在 中找到build/target/product）添加该行（检查所有其他人的位置）

PRODUCT_PACKAGES += < what you have defined in LOCAL_MODULE, it should be your app folder name >

Compile the AOSP and you have a brand new app installed on the system.

编译 AOSP，您就会在系统上安装一个全新的应用程序。

Notes

笔记

• If your APK is already signed, use the special value PRESIGNEDas value for LOCAL_CERTIFICATE
• If you want your APK to end up in the /data/app/directory, add the line LOCAL_MODULE_PATH := $(TARGET_OUT_DATA)before the line include $(BUILD_PREBUILT)

• 如果您的 APK 已经签名，请使用特殊值PRESIGNED作为LOCAL_CERTIFICATE
• 如果您希望您的 APK 最终出现在/data/app/目录中，请在该行LOCAL_MODULE_PATH := $(TARGET_OUT_DATA)之前添加该行include $(BUILD_PREBUILT)

The Android.mk presented above will install the APK in /system/app

上面显示的 Android.mk 将在 /system/app 中安装 APK

If you wish to install the APK in /data/app you will need to add the following the line to Android.mk before line include $(BUILD_PREBUILT)

如果您希望在 /data/app 中安装 APK，则需要将以下行添加到 Android.mk 行之前 include $(BUILD_PREBUILT)

LOCAL_MODULE_PATH := $(TARGET_OUT_DATA)

You could also do the following in the target output dir:

您还可以在目标输出目录中执行以下操作：

<path-to-your-build-dir>/host/linux-x86/bin/simg2img system.img temp.img
mkdir system_root
sudo mount -t ext4 -o loop temp.img system_root

At this point you can make whatever changes you'd like to the files in system_root, i.e. adding apks to system/app etc...

此时，您可以对 system_root 中的文件进行任何您想要的更改，即将 apks 添加到 system/app 等...

When you're done just go back down to the output dir and do:

完成后，返回到输出目录并执行以下操作：

sudo umount system_root
<path-to-your-build-dir>/host/linux-x86/bin/img2simg temp.img system.img

You can now flash system.img using fastboot as usual.

您现在可以像往常一样使用 fastboot 刷新 system.img。
