升级Android Studio至3.1.2后无法调试C++代码求助

我把Android Studio升级到3.1.2版本后，调试应用时遇到了棘手的问题——每次尝试启动调试，模拟器/设备上会弹出提示（图片如下），同时错误日志里抛出了Execution finished com.intellij.execution.ExecutionException相关异常，最后进程直接以exit code 0结束，完全没法正常进入调试流程。

错误日志详情：

有没有朋友能帮忙解决这个调试问题？

解决方案 #

我之前碰到过几乎一模一样的问题，试了几个方法后解决了，你可以逐一尝试：

• 清理缓存并重启Android Studio
  点击菜单栏的 File → Invalidate Caches / Restart，选择Invalidate and Restart选项。升级后缓存不一致是常见问题，清理后重启往往能解决很多奇怪的bug。

• 检查NDK版本兼容性
  Android Studio 3.1.2对NDK版本有特定要求，建议打开File → Project Structure → SDK Location查看当前NDK版本。如果是较旧的版本，尝试更新到r17c（这个版本和AS 3.1.x系列适配性很好）；如果已经是对应版本，删除本地.ndk文件夹后重新下载完整NDK包。

• 重新配置调试器设置
  打开Run/Debug Configurations，找到你的调试配置，切换到Debugger标签页，把Debug type设置为Auto或者明确选择Native（如果你的应用包含Native代码），保存配置后再尝试调试。

• 重置设备/模拟器的调试状态
  确保真机开启了USB调试模式，模拟器使用的是最新的系统镜像。可以尝试重启设备/模拟器，然后重新连接到Android Studio，再启动调试。

• 替换LLDB版本
  有时候AS自带的LLDB版本会有兼容性问题，你可以手动替换成稳定版本：

  1. 找到AS安装目录下的lldb/3.1文件夹
  2. 下载对应版本的稳定LLDB包（比如3.1.1版本）
  3. 替换原文件夹内容后重启AS

如果以上方法都无效，建议创建一个全新的测试项目，看看能不能正常调试——以此判断是项目本身的配置问题，还是Android Studio的全局设置问题。
