In Android API level 23 and above, dynamic loader is able to load .so file directly from APK, which is zip file. https://android.googlesource.com/platform/bionic/+/master/ android-changes-for-ndk-developers.md# opening-shared-libraries-directly-from-an-apk The .so file is page aligned and uncompressed, so ObjectFileELF::GetModuleSpecifications works with .so file offset and size directly from zip file without extracting it. (D152757) GDBRemoteCommunicationServerCommon::GetModuleInfo returns a module spec to LLDB with "zip_path!/so_path" file spec, which is passed through from Android dynamic loader, and the .so file offset and size. PlatformAndroid::DownloadModuleSlice uses 'shell dd' to download the .so file slice from the zip file with the .so file offset and size. Differential Revision: https://reviews.llvm.org/D152759
