Library Usage

Simply load or inject the library with whichever method and let it do its thing. run logcat with tag filter "UE4Dump3r" for dump logs. The dump output will be at the game's external data folder (/sdcard/Android/data/< game >/files) to avoid external storage permission.

Executable Usage

You will have to push the dumper in an executable directory like /data/local/tmp then give it execute permission. Its recommended to have adb, you can check push script for this. Use the compatible dumper, if game is 64bit use arm64 or x86_64, if 32bit then use arm or x86 version.

Usage: ./UE4Dump3r [-h] [-o] [ options ]

Required arguments:
   -o, --output        specify output directory path.

Optional arguments:
   -h, --help          show available arguments.
   -p                  specify game package ID in advance.
   -dump_lib           dump UE4 library from memory.

Output Files

Headers

C++ headers that you can use in your source, however the headers might not compile directly without a change

AIOHeader.hpp

An all-in-one dump file header

ObjectsDump.txt

ObjObjects dump

script.json

If you are familiar with Il2cppDumper script.json, this is similar. It contains a json array of function names and addresses

Adding a new game to the Dumper

Follow the prototype in GameProfiles You can also use the provided patterns to find GUObjectArray, GNames or NamePoolData.

How to compile

You need to have make installed on your OS and an ndk (I used ndk v25), then simply run build script. make sure to set NDK_Home in Makefile.
