Building

Requirements

• jarsigner

LibZombieCafeExtension

LibZombieCafeExtension is an extra library that applies runtime patches to the games libZombieCafeAndroid.so

cd src/lib/cpp
mkdir build
cd build

make

Running tools

Part of the build process for this project is running custom tools to convert human readable file structure in to the games expected file formats.

go run ./tool/build_tool/ -i src/ -o build/

cp src/lib/cpp/build/libZombieCafeExtension.so ./build/lib/armeabi/libZombieCafeExtension.so

apktool b ./build -o ./build/out/out.apk

jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore debug.keystore -storepass zombiecafe ./build/out/out.apk alias_name

adb install ./build/out/out.apk
