Building from source

You will need:

• Python 3.12
• Java 17 JDK
• Android Studio/Android dev tools (Specifically, zipalign)
• Some understand of android development

You can invoke the python script directly using python build.py ... or using the bash script: ./build.sh .... Use whichever you prefer.

1. Copy zipalign or zipalign.exe from your android build tools (ver. 35) into tools
2. If you want a release build, generate a keystore and name it release.keystore in keystores using keytool
3. Get a copy of the tumblr apk version 34.3.0.110 and place it inside source-apk (Naming doesn't matter)
4. Run the build script using python build.py build r
5. Copy the output apk (in build/apk/tumblr-ykit.apk) wherever you need it.

Build commands and flags:

./build.sh extract - Extracts the apk's contents into build/extracted

./build.sh clean - Cleans up the workspace by deleting the build directory

./build.sh assemble - Assembles the ykit apk without signing or aligning it

./build.sh build [flags] - Builds the apk and aligns and signs it using the specified key.

Build flags:

a - Deploy to android studio in ~/ApkProjects/tumblr-ykit. To generate one, open AS, and load the apk. From then on you will not need to repeat this step unless you want to analyze the code (TODO: This explanation is garbage.)

r - Sign using release keystore keystores/release.keystore (You will have to create it yourself)

d - Sign using the debug keystore keystores/debug.keystore (It will be created automatically)
