hi,粉丝朋友:

近期又粉丝朋友聊到了如果做aosp系统应用开发,有什么工具或者方式来导入代码可以正常跳转和代码提示等?

Android Studio导入系统源码

针对这个问题其实我课程里面的[入门课就有有讲解android studio导入整套系统源码]的详细说明,这里就再次补充一下android studio导入android系统源码
1、生成对应的android.ipr和android.iml文件

 make idegen -j4
 “development/tools/idegen/idegen.sh” (报错find: ‘out/target/product/generic_x86_64/root/d’: Permission denied没有关系不影响ipr和iml文件生成)
 sudo chmod 777 android.iml android.ipr
 2、有了ipr和iml,删减一部分android.iml的内容,主要原因源码太多,要排除部分没用项目,还有就是依赖部分只留下自己moudle就可以
 把android.iml中的excludeFolder标签都删除用以下标签
<excludeFolder url="file://$MODULE_DIR$/art" />
      <excludeFolder url="file://$MODULE_DIR$/bionic" />
      <excludeFolder url="file://$MODULE_DIR$/bootable" />
      <excludeFolder url="file://$MODULE_DIR$/build" />
      <excludeFolder url="file://$MODULE_DIR$/compatibility" />
      <excludeFolder url="file://$MODULE_DIR$/cts" />
      <excludeFolder url="file://$MODULE_DIR$/dalvik" />
      <excludeFolder url="file://$MODULE_DIR$/developers" />
      <excludeFolder url="file://$MODULE_DIR$/developers/samples" />
      <excludeFolder url="file://$MODULE_DIR$/development" />
      <excludeFolder url="file://$MODULE_DIR$/device" />
      <excludeFolder url="file://$MODULE_DIR$/device/google" />
      <excludeFolder url="file://$MODULE_DIR$/device/sample" />
      <excludeFolder url="file://$MODULE_DIR$/docs" />
      <excludeFolder url="file://$MODULE_DIR$/external" />
      <excludeFolder url="file://$MODULE_DIR$/flashing-files" />
      <excludeFolder url="file://$MODULE_DIR$/frameworks/base/docs" />
      <excludeFolder url="file://$MODULE_DIR$/hardware" />
      <excludeFolder url="file://$MODULE_DIR$/kernel" />
      <excludeFolder url="file://$MODULE_DIR$/libcore" />
      <excludeFolder url="file://$MODULE_DIR$/libnativehelper" />
      <excludeFolder url="file://$MODULE_DIR$/out" />
      <excludeFolder url="file://$MODULE_DIR$/out/soong/.intermediates" />
      <excludeFolder url="file://$MODULE_DIR$/pdk" />
      <excludeFolder url="file://$MODULE_DIR$/platform_testing" />
      <excludeFolder url="file://$MODULE_DIR$/prebuilt" />
      <excludeFolder url="file://$MODULE_DIR$/prebuilts" />
      <excludeFolder url="file://$MODULE_DIR$/sdk" />
      <excludeFolder url="file://$MODULE_DIR$/shortcut-fe" />
      <excludeFolder url="file://$MODULE_DIR$/system" />
      <excludeFolder url="file://$MODULE_DIR$/test" />
      <excludeFolder url="file://$MODULE_DIR$/toolchain" />
      <excludeFolder url="file://$MODULE_DIR$/tools" />

把orderEntry标签都删除,只剩下如下两个即可以,这样跳转时候就不会跳其他jar

 <orderEntry type="sourceFolder" forTests="false" />
    <orderEntry type="jdk" jdkName="Android API 33 Platform" jdkType="Android SDK" />

这样android studio就完全可以进行相关的跳转了,同时各个app其实也可以进行跳转,如下图的Settings:

这种其实也有一些androidx库依赖标红啥的,这个相对比较少影响不是太大,不过这个也可能是很多同学不喜欢的点,那么有啥更好办法解决么?当然有,那就是今天主题AIDEGen

AIDEGen导入各个模块代码

AIDEGen相关文档:
tools/asuite/aidegen/README.md

首先看它的相关官方readme,英文的,其实也比较好懂,这里就不做翻译了,我相信也完全可以看懂

AIDEGen

AIDEGen aims to automate the project setup process for developers to work on
Java or C/C++project in popular IDE environment. Developers no longer need to manually
configure an IntelliJ project, such as all the project dependencies. It’s a
command line tool that offers the following features:

  • Configure Android Studio or IntelliJ project files with the relevant module
    dependencies resolved.

  • Launch IDE for a specified sub-project or build target, i.e. frameworks/base
    or Settings.

  • Launch IDE for specified folder(s) which contains build targets, i.e. cts.

  • Auto configure JDK and Android coding style for IntelliJ.

(上面其实就是说明了一下AIDEGen是干啥的,大概意思就是它是一个自动生成项目配置文件,针对不同的主流ide都是可以的,比如 Android Studio or IntelliJ project等,就不需要我们自己针对不同ide来搞对应项目)

1. Prerequisites:

  • IDE installation, choose one of prefer IDE, including Android Studio,
    IntelliJ IDEA, Eclipse, CLion and VS Code.

  • Setup Android development environment.

$ source build/envsetup.sh && lunch 

(以上是预备条件,配置好aosp的env和lunch,而且要本身系统安装好了的对应的ide,比如Android Studio,IntelliJ IDEA, Eclipse, CLion and VS Code)

2. Basic Usage:

Example 1: Launch IDE with module name

Example to generate and launch IntelliJ project for framework and Settings:
可以直接使用module name来进行对应的启动

$ aidegen Settings framework

Example 2: Launch IDE with module path

Example to generate and launch IntelliJ project for framework and Settings:
可以直接使用module path来进行对应的启动

$ aidegen packages/apps/Settings frameworks/base

Example 3: Launch IDE with build skipped

Example to generate and launch IntelliJ project for framework and Settings and
skip build time:
这里可以用-s来跳过编译,一般使用这种如果已经编译了的话

$ aidegen Settings framework -s

Example 4: Launch IDE with native module

Example to generate and launch CLion project:

$ aidegen  -i c

The native projects will be launched in CLion and you have to select,
Tools > CMake > Change Project Root
Change project root to the source directory: the relative path which is the directory shown in CLion’s project view. For example, if frameworks/base/media is your project, please change project root directly to frameworks/base/media.

3. Optional arguments:

Developers can also use the following optional arguments with AIDEGen commands.

Option Long option Description
-d --depth The depth of module referenced by source.
-i --ide Launch IDE type, j=IntelliJ s=Android Studio e=Eclipse c=CLion v=VS Code
-p --ide-path Specify user’s IDE installed path.
-n --no_launch Do not launch IDE.
-r --config-reset Reset all AIDEGen’s saved configurations.
-s --skip-build Skip building jars or modules.
-v --verbose Displays DEBUG level logging.
-a --android-tree Generate whole Android source tree project file for IDE.
-e --exclude-paths Exclude the directories in IDE.
-l --language Launch IDE with a specific language,j=java c=C/C++ r=Rust
-h --help Shows help message and exits.

4. Troubleshooting tips:

If you get an error like: “Dependent modules dictionary is empty.” or other errors, try a make
clean.

5. FAQ:

Q1. If I already have an IDE project file, and I run command AIDEGen to generate
the same project file again, what’ll happen?

A1: The former IDEA project file will be overwritten by the newly generated one
from the aidegen command.

Q2: When do I need to re-run AIDEGen?

A2: Re-run AIDEGen after repo sync.

6. Hint:

  1. In IntelliJ, uses [File] > [Invalidate Caches / Restart…] to force
    project panel updated when your IDE didn’t sync.

  2. If you run aidegen on a remote desktop, make sure there is no IntelliJ
    running in a different desktop session.

实战体验Settings

命令:

aidegen packages/apps/Settings -i s -s

针对androidx等也不会报错

相对系统app来说确实体验还是很不错,比源码整体导入那种相对更好一些,也非常简单,不需要为了Setting导入整套代码,跳转framework部分的代码也是正常的:
