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？ 更多内容： https://blog.csdn.net/learnframework/article/details/130016893

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

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

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.

OptionLong optionDescription-d--depthThe depth of module referenced by source.-i--ideLaunch IDE type, j=IntelliJ s=Android Studio e=Eclipse c=CLion v=VS Code-p--ide-pathSpecify user’s IDE installed path.-n--no_launchDo not launch IDE.-r--config-resetReset all AIDEGen’s saved configurations.-s--skip-buildSkip building jars or modules.-v--verboseDisplays DEBUG level logging.-a--android-treeGenerate whole Android source tree project file for IDE.-e--exclude-pathsExclude the directories in IDE.-l--languageLaunch IDE with a specific language,j=java c=C/C++ r=Rust-h--helpShows 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:

In IntelliJ, uses [File] > [Invalidate Caches / Restart…] to force project panel updated when your IDE didn’t sync. If you run aidegen on a remote desktop, make sure there is no IntelliJ running in a different desktop session.

6. Feedback:

If you have any questions or feedback, contact aidegen_tnn@google.com.

If you have any bugs or feature requests email them to buganizer-system+429701@google.com.

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：
