这篇文章将介绍如何在Android系统中内置第三方apk

一、准备工作

• 编译好的Android源码
• Android apk文件：也就是安卓应用安装包

二、步骤

（1）在源码packages/apps目录下以我们需要内置的APK名字来创建一个新的文件夹

以 qqmusic.apk 为例,在Android_12_AOSP/packages/apps目录下新建qqmusic文件夹

cd Android_12_AOSP/packages/apps/mkdir qqmusic

（2）将 qqmusic.apk 放入建好的文件夹中，在文件夹中创建 Android.mk 文件

cd Android_12_AOSP/packages/apps/qqmusic/touch Android.mk

（3）编辑 Android.mk 文件内容，内容如下

LOCAL_PATH:=$(call my-dir)include $(CLEAR_VARS)LOCAL_class="lazy" data-src_FILES := CarSkin.apkLOCAL_MODULE_CLASS := APPS#可以为user、eng、tests、optional，optional代表在任何版本下都编译LOCAL_MODULE_TAGS := optional#编译模块的名称LOCAL_MODULE := CarSkin#可以为testkey、platform、shared、media、PRESIGNED（使用原签名），platform代表为系统应用LOCAL_CERTIFICATE := PRESIGNED#不设置或者设置为false，安装位置为system/app，如果设置为true，则安装位置为system/priv-app?LOCAL_PRIVILEGED_MODULE := false#module的后缀，可不设置LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX)# 关闭预编译，不会生成OAT文件LOCAL_DEX_PREOPT := trueLOCAL_PRODUCT_MODULE := trueinclude $(BUILD_PREBUILT)

或

# TestLOCAL_PATH := $(call my-dir)include $(CLEAR_VARS)LOCAL_MODULE := qqmusicLOCAL_MODULE_CLASS := APPS#可以为user、eng、tests、optional，optional代表在任何版本下都编译LOCAL_MODULE_TAGS := optionalLOCAL_BUILT_MODULE_STEM := package.apkLOCAL_DEX_PREOPT := nostrippingLOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX)#不设置或者设置为false，安装位置为system/app，如果设置为true，则安装位置为system/priv-appLOCAL_PRIVILEGED_MODULE := true#可以为testkey、platform、shared、media、PRESIGNED（使用原签名），platform代表为系统应用LOCAL_CERTIFICATE :=  platform#覆盖安装#LOCAL_OVERRIDES_PACKAGES := DeviceTest RKDeviceTestLOCAL_class="lazy" data-src_FILES := $(LOCAL_MODULE).apkLOCAL_MULTILIB := 32#LOCAL_REQUIRED_MODULES :=#JNI_LIBS :=#$(foreach FILE,$(shell find $(LOCAL_PATH)/lib/ -name *.so), $(eval JNI_LIBS += $(FILE)))#LOCAL_PREBUILT_JNI_LIBS := $(subst $(LOCAL_PATH),,$(JNI_LIBS))include $(BUILD_PREBUILT)

预装带源码的APP到系统

Android.bp文件

// Android依赖导入android_library_import {    name: "com.google.android.material_material",    aars: ["material-1.6.0.aar"],    sdk_version: "current",    min_sdk_version: "14",    static_libs: [        "androidx.annotation_annotation",        "androidx.appcompat_appcompat",        "androidx.cardview_cardview",        "androidx.coordinatorlayout_coordinatorlayout",        "androidx-constraintlayout_constraintlayout",        "androidx.core_core",        "androidx.dynamicanimation_dynamicanimation",        "androidx.annotation_annotation-experimental",        "androidx.fragment_fragment",        "androidx.lifecycle_lifecycle-runtime",        "androidx.recyclerview_recyclerview",        "androidx.transition_transition",        "androidx.vectordrawable_vectordrawable",        "androidx.viewpager2_viewpager2",          "androidx.drawerlayout_drawerlayout",    ],}//// Build rule for  app.//android_app {    //name: "DebuggingRestrictionController",    //class="lazy" data-srcs: ["app/class="lazy" data-src/main/java*.java", "soong/BuildConfig.java", "soong/FirebaseApplication.java"],    //resource_dirs: ["app/class="lazy" data-src/main/res"],    //manifest: "soong/AndroidManifest.xml",    //sdk_version: "system_current",    //certificate: "platform",    //privileged: true,    //optimize: {    //    enabled: true,    //    proguard_flags_files: ["app/proguard-rules.pro"],    //},        name: "CarSkin",        //使用以下构建标记向 product 分区中安装模块。    product_specific: true,        //导入 class="lazy" data-src 文件内容    class="lazy" data-srcs: [        "class="lazy" data-src*.java"     ],        //资源导入模块，如果aar包中带资源文件，需要将aar包解压拷贝资源文件，在源码根目录下新建一个 res-lottie 文件夹，将资源文件拷入此目录    //resource_dirs: [    //    "res-lottie",    //],        libs: [      "res-lottie"    ],        //libs: [],        sdk_version: "current",    min_sdk_version: "14",    target_sdk_version: "current",        //platform_apis:true,    certificate: "platform",    //privileged: true,    //system_ext_specific: true,    //导入manifest文件    manifest: "app/class="lazy" data-src/main/AndroidManifest.xml",    //添加manifest文件模块    //additional_manifests: [      //  "AndroidManifest-common.xml",    //],        //导入静态库    static_libs: [        "com.google.android.material_material"    ],        //apptflags: [    //  "--extra-packages",    //  "com.google.android.material" //导入aar包包名，用于生成 R 文件    //],}

（4）下面我们需要将将创建的qq音乐编译模块加入到编译系统，我们找到 /Android_12_AOSP/build/make/target/product/handheld_product.mk

文件，在文件下面这个位置加入qqmusic

PRODUCT_PACKAGES += \    apps \    qqmusic 

进入源码根目录，重新编译

cd Android_12_AOSP/source build/envsetup.sh # 导入环境lunch 12  # 选择系统make -j6  # 编译make snod  # 快速打包生成最新的system.img文件

问题记录：

注意：每次内置应用或修改mk文件时，一定要重新编译 system.img 然后在启动模拟器

错误1

解决方法

修改Android.mk，添加LOCAL_ENFORCE_USES_LIBRARIES := false

LOCAL_PATH := $(call my-dir)include $(CLEAR_VARS)# Module name should match apk name to be installedLOCAL_MODULE := SogouInputLOCAL_MODULE_TAGS := optionalLOCAL_class="lazy" data-src_FILES := $(LOCAL_MODULE).apkLOCAL_MODULE_CLASS := APPSLOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX)LOCAL_CERTIFICATE := PRESIGNEDLOCAL_ENFORCE_USES_LIBRARIES := falseinclude $(BUILD_PREBUILT)

错误2

输入命令报错

adb install -r /home/lai/下载/SogouInput_v11.7_Build_40e311fcaf0_20220714_android_sweb.apk

adb: failed to install /home/lai/下载/SogouInput_v11.7_Build_40e311fcaf0_20220714_android_sweb.apk: Failure [INSTALL_FAILED_NO_MATCHING_ABIS: Failed to extract native libraries, res=-113]

问题当前的app使用的native libraries与模拟器的CPU架构不一致所导致的

错误3

错误4

问题：系统卡在开机动画进不去

原因：内置一个apk时，因为软件签名问题，导致系统服务启动不了

解决方法：将软件删掉重新编译就行

过程中常用的命令

通过adb安装应用

adb install -r /home/lai/下载/SogouInput_v11.7_Build_40e311fcaf0_20220714_android_sweb.apk

通过adb查看安装的应用包名

adb shell pm list packages  #只显示应用包名 adb shell pm list packages -f #显示应用包名及路径adb shell dumpsys package > ./package.txt

adb shell am switch-user 10adb shell pm list users

执行make clean将会会删除out/目录下所有内容。

make clean

执行make clobber效果等同于make clean，也是删除out/目录下所有内容。

make clobber

执行make installclean将会删除installclean_files,installclean_files

make installclean

查询手机cpu命令行：

adb shell getprop ro.product.cpu.abi

开机日志的获取：

adb logcat -b main -b system -b radio -b events -v time > bootLog.log

adb 日志获取

adb logcat

通过关键字查找文件所在位置

grep "Calendar" ./ -rngrep "Contacts" ./ -rn

自定义内置apk流程

（1）在源码根目录 /vendor 下新建一个test 文件夹

mkdir test

（2）在 test 文件目录下新建一个 test.mk 文件

touch test.mk

（3）在源码test目录下以我们需要内置的APK名字来创建一个新的文件夹

• 以 ABC.apk为例,在test目录下新建ABC文件夹

mkdir ABC

（4）将 ABC.apk 放入ABC文件夹中，在文件夹ABC中创建 Android.mk 文件

touch Android.mk

Android.mk文件的内容如下：

LOCAL_PATH := $(call my-dir)include $(CLEAR_VARS)LOCAL_MODULE := ABCLOCAL_MODULE_TAGS := optionalLOCAL_class="lazy" data-src_FILES := ABC.apkLOCAL_MODULE_CLASS := APPSLOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX)LOCAL_PRIVILEGED_MODULE := falseLOCAL_CERTIFICATE := platforminclude $(BUILD_PREBUILT)

（5）打开我们建好的 test.mk 文件，在里面加入以下内容，将ABC模块加入到编译系统

PRODUCT_PACKAGES += \    ABC \    user 

（6）将我们建的 test.mk 加入到编译环境中，这样我们后面需要新加入模块就能直接在test.mk里配置了

我们在源码根目录下找到 device/rockchip/rk3588/device.mk 文件

注：这个路径以及上面的/vendor目录一般是项目中存放内置apk的路径，不同项目路径可能不同，根据自己实际路径来选择，一般都是在源码根目录的 /device 目录下

将下面内容加入到文件如下对应位置

#$(call inherit-product-if-exists, vendor/rockchip/common/npu/npu.mk)$(call inherit-product-if-exists, vendor/test/test.mk) # 我们配置的文件,加入进来$(call inherit-product-if-exists, vendor/firefly/firefly.mk)

（7）最后我们进入源码根目录重新编译源码

进入源码根目录，重新编译

source build/envsetup.sh # 导入环境lunch   # 选择系统，选择自己的系统make installclean # 清除out目录下对应板文件夹中的内容make -j6  # 编译,如果这一步生成了最新的镜像文件，那不需要进行下一步了make snod  # 快速打包生成最新的system.img文件

后面我们如果需要继续添加新apk，只需要重复（3）（4）（5）（7）步骤就行
