Android Tools - A set of binaries

This repo contains a collection of some Android (but not exclusively) tools for various usages and also some libraries (though some are mini-ports) that might be useful.

Note: For this project, I worked on it when I was learning, so it is not that perfect and not everything is correct.

Tools

• e2fsdroid
• ext2simg
• magiskboot
• mke2fs
• e2fstool
• img2simg
• make_ext4fs
• simg2img

Libraries

• libbase (mini-port)
• libext2_e2p
• libext2_support
• liblzma
• libsparse
• libbz2
• libext2_misc
• libext2_uuid
• libmagiskbase
• libz (old port)
• libcutils (mini-port)
• libext2_profile
• libext2fs
• libmincrypt
• libzopfli
• libext2_blkid
• libext2_quota
• libfdt
• libnt
• libext2_com_err
• libext2_ss
• liblz4
• libselinux

Build

• Using MSYS2 clang64 environment with mingw-w64-clang-x86_64-toolchain packages group, LLVM version 14 and up, run mingw32-make command.
• if built a non-static variant, all DLLs in out/obj/lib/shared must be present in your PATH for successful execution.

What's changed:

• e2fsdroid, ext2simg and mke2fs had many UBs and most of them are fixed.
• mke2fs creates 1k block-sized images without crashing unlike the official release.
• mke2fs, img2simg and ext2simg makes valid sparse images.
• make_ext4fs is now using the re-based C++ libsparse.
• All problems with paths should be resolved, both Unix-like and Windows styles work.
• e2fsdroid and make_ext4fs both work when file config (uid, gid, mode and capability config) or/and selinux contexts are provided.

For Windows

• There's some UBs/SFs that need to be addressed (test and report).
• Tested and working operations are limited.
