本文档以系统应用Launcher为例，带大家了解如何通过系统源码编译应用的方式来打包预安装应用。

  • 开发环境：Windows 11
  • 编译环境：Ubuntu 22.04
  • 开发板型号：DAYU 200（RK3568）
  • 系统版本：OpenHarmony-3.2-Release
  • 涉及仓库：applications_launcher
  • 在OpenHarmony系统中预安装应用的hap包会随系统编译打包到镜像中，目前有两种编译预安装应用hap包的方式，一种为随系统编译时，编译应用源码生成hap包的方式，另一种是将已生成的hap包放入系统源码中，再进行打包的方式。后者需要开发者使用DevEco Studio或其它途径，把应用源码编译构建为hap包，再将hap放入系统源码中。

3.2-Release系统编译Launcher

 删除或注释系统中默认的Launcher应用hap包编译方式。

文件位置：applications/standard/hap/BUILD.gn 

group("hap") {
  deps = [
    	...
      # "//applications/standard/hap:launcher_hap", // 直接删除或注释，不参与编译
      # "//applications/standard/hap:launcher_settings_hap",  // 直接删除或注释，不参与编译
    	...
  ]
 }

在applications/standard/launcher/product/phone目录中增加BUILD.gn文件。

97c3a3994e95a287c175053384a364c4d1ffe7.png

内容如下：

import("//build/ohos.gni")

ohos_hap("launcher_hap") {
  hap_profile = "src/main/module.json"
  deps = [
    ":launcher_js_assets",
    ":launcher_resources",
  ]
  certificate_profile = "../../signature/launcher.p7b"
  hap_name = "Launcher_OS"
  part_name = "prebuilt_hap"
  subsystem_name = "applications"
  js_build_mode = "release"
  module_install_dir = "app/com.ohos.launcher"
}

ohos_js_assets("launcher_js_assets") {
  ets2abc = true
  source_dir = "src/main/ets"
}

ohos_resources("launcher_resources") {
  sources = [ "src/main/resources", "../../common/src/main/resources" ]
  deps = [ ":launcher_app_profile" ]
  hap_profile = "src/main/module.json"
}

ohos_app_scope("launcher_app_profile") {
  app_profile = "../../AppScope/app.json"
  sources = [ "../../AppScope/resources" ]
}
  • 此处把产物名称hap_name定义为Launcher_OS是为了区分原系统源码中默认的hap包名称，实际可以填写为Launcher。
  • 因为launcher_hap中使用了其它har（common）中的资源，所以launcher_resources中的sources需要添加依赖的resources资源目录，在步骤3中launcher_settings_hap
    中的配置也是如此。

在applications/standard/launcher/feature/settings目录中增加BUILD.gn文件。

764a27007b9d1a9e1c949640a77b5d2da07910.png

内容如下：

import("//build/ohos.gni")

ohos_hap("launcher_settings_hap") {
  hap_profile = "src/main/module.json"
  deps = [
    ":launcher_settings_js_assets",
    ":launcher_settings_resources",
  ]
  certificate_profile = "../../signature/launcher.p7b"
  hap_name = "Launcher_Settings_OS"
  part_name = "prebuilt_hap"
  subsystem_name = "applications"
  js_build_mode = "release"
  module_install_dir = "app/com.ohos.launcher"
}

ohos_js_assets("launcher_settings_js_assets") {
  ets2abc = true
  source_dir = "src/main/ets"
}

ohos_resources("launcher_settings_resources") {
  sources = [ "src/main/resources", "../../common/src/main/resources" ]
  deps = [ ":launcher_settings_app_profile" ]
  hap_profile = "src/main/module.json"
}

ohos_app_scope("launcher_settings_app_profile") {
  app_profile = "../../AppScope/app.json"
  sources = [ "../../AppScope/resources" ]
}
  • 此处把产物名称hap_name定义为Launcher_Settings_OS是为了区分原系统源码中默认的hap包名称，实际可以填写为Launcher_Settings。

因为系统编译只可读取json后缀的配置文件，所以需要把应用源码中的app.json5和module.json5文件复制，并改名为app.json和module.json文件。

复制applications/standard/launcher/AppScope/app.json5文件为app.json。

复制applications/standard/launcher/product/phone/src/main/module.json5文件为module.json。

69a24c198b3180b3be22411e6c45265f43e7c1.png

复制applications/standard/launcher/feature/settings/src/main/module.json5文件为module.json。

在applications/standard/hap/ohos.build文件module_list中增加launcher_hap模块和launcher_settings_hap模块编译。

{
  "subsystem": "applications",
  "parts": {
    "prebuilt_hap": {
	  	...
      "module_list": [
       	...
        "//applications/standard/launcher/product/phone:launcher_hap",
        "//applications/standard/launcher/feature/settings:launcher_settings_hap",
        ...
      ]
    }
  }
}

修改预编译配置build/prebuilts_download_config.json文件，把launcher依赖增加到npm_install_path列表中。

{
  "prebuilts_download_dir": "../OpenHarmony_canary_prebuilts",
  "npm_install_path": [
    "developtools/ace_ets2bundle/compiler",
    "developtools/ace_js2bundle/ace-loader",
    "third_party/jsframework",
    "arkcompiler/ets_frontend/ts2panda",
    "arkcompiler/ets_frontend/legacy_bin/api8",
    "interface/sdk-js/build-tools",
    "applications/standard/launcher/common",
    "applications/standard/launcher/feature/appcenter",
    "applications/standard/launcher/feature/bigfolder",
    "applications/standard/launcher/feature/form",
    "applications/standard/launcher/feature/gesturenavigation",
    "applications/standard/launcher/feature/numbadge",
    "applications/standard/launcher/feature/pagedesktop",
    "applications/standard/launcher/feature/recents",
    "applications/standard/launcher/feature/smartdock",
    "applications/standard/launcher/feature/settings",
    "applications/standard/launcher/product/phone"
  ],
  ...
}

执行预编译指令。

bash build/prebuilts_download.sh --skip-ssl

可以在应用源码中看到应用内的依赖已经被正确的加载。

执行源码编译指令。如果以下2个目录产物正确，则说明应用源码编译方式修改成功。

在out/rk3568/obj/applications/standard/launcher目录中，会生成2个hap的编译产物。

在out/rk3568/packages/phone/system/app/com.ohos.launcher目录中，是实际系统环境中的hap包产物。
