描述

Description

Build machines run out of disk space without symbol stripping. However, enabling symbol stripping removes debug symbols, which makes the app non-debuggable and breaks adb shell run-as access to internal storage. For test infrastructure, we need both: debuggable builds and stripped binaries.

Tasks

  • Keep the app debuggable during build
  • Strip debug symbols from native libraries after the build step

研究方向
Investigate the Android build process in dotnet/runtime, focusing on how native libraries are built and packaged. Relevant files are likely in src/mono or src/native directories, along with MSBuild targets that handle APK creation. The goal is to add a post build step that strips debug symbols from .so files while preserving the debuggable flag in AndroidManifest. Examine existing build targets in Microsoft.Android.Sdk for reference. No linked pull requests or additional comments provide further details, so the contributor should start by locating the build scripts and proposing a mechanism to strip symbols after the build completes.
