# Building 1.7.4 Fix from source The public source edition intentionally excludes the Local API, tunnel connectors, and protected-build payloads. It otherwise uses the same 1.7.4 Fix feature core for the supported domestic and Google Play DeepSeek packages. Requirements: JDK 17, Bash, Android SDK Platform 35 or newer, Android Build Tools (`aapt2`, `d8`, `zipalign`, and `apksigner`), `zip`, and `curl`. Set `ANDROID_SDK_ROOT` or `ANDROID_HOME`, then run: ```bash bash scripts/build-all.sh ``` For one channel only: ```bash (cd module-universal && bash build.sh) (cd module-universal && GOOGLE_PLAY_BUILD=true bash build.sh) ``` The scripts create a local development signing key when needed. Do not use that key as a production identity. Build products and keys are ignored by Git. The universal entry declares Xposed API 82 as its minimum and has no maximum; the compatibility regression exercises API values 82 through 102.
