如何使用本机 (C++) 符号在调试模式下构建 Android React Native 源代码? [英] How to build Android React Native source code in debug mode with native (C++) symbols?

问题描述

我想构建带有调试本机代码(Java 和 C++)选项的 React-Native 代码，到目前为止我所做的:

1. 克隆 react-native 源代码
2. 将 NDK_DEBUG=1 添加到 buildReactNdkLib gradle 任务 -

   I want to build the React-Native code with the option to debug native code (Java & C++), what I did till now:

   1. Clone react-native source code
   2. Added NDK_DEBUG=1 to buildReactNdkLib gradle task - code
   3. I had to add some files to the make file of the folly project - code
   4. I added the command not to stip the .so files in one of the makefiles - code - actually I was sure that NDK_DEBUG=1 is doing this by default, but it wasn't

   The result is that the build is passing and the so files are really not-stripped, but the app crashes in Runtime

   解决方案

   Just found the answer, I don't need set NDK_DEBUG=1, all the not-stripped files placed under build/tmp/buildReactNdkLib/local//

   You just need to configure the symbol directory in Android-Studio:
