sudo deepin-editor android.iml
在源码的根目录创建start_emulator.sh脚本，为了方便的启动模拟器，输入以下内容 后执行
在系统源码找到ActivityStarter这个类，在startActivityMayWait这个方法打断点
点击菜单的Run–>Attach Debugger to Android Process，勾选Show all processer，选择system_process 随便启动app 触发断点
gdbclient.py -p 6018 --setup-forwarding vscode 执行之后 vscode 附加 发现链接失败时
- Android - 系统源码调试
- Android Java层源码调试
- 编译idegen
- 编辑导入配置
- 导入Android Studio
- 排除tests 目录 右键
- 配置 Android源码项目
- 点击File -> Project Structure–>SDKs配置项目的JDK、SDK。
- 根据源码版本选择对应API级别 这里使用的Android10 对应29
- 点击 Edit API SDK
- Modules Structure
- 配置Run/Debug Configurations
- 开始调试 - 使用教程
- 常用命令
- 案例一
- 第三方app触发 系统java层 调试成功
- Android Native层源码调试 - 需以源码编译的模拟器启动
- 前置配置 source build/envsetup.sh lunch 22
- 配置 VScode 运行和调试
- 获取vscodelunch.json 配置
- 启动native调试
- 最后 打开AS open Android ipr 项目
- vscode 附加调试失败
- 手动运行gdbserver
- 异常问题处理
