llm-android-cross-build

Cross-compile an LLM library for Android AArch64 by applying CMake presets and configuring the Android NDK toolchain. This process generates binaries specifically configured for mobile deployment targets.

Building LLMs for Android requires the Android NDK, CMake, and ADB for deployment. The workflow involves compiling libraries for AArch64, pushing binaries via ADB, and running models directly on the device.

Yes, CMake presets support configuring the Android NDK toolchain for LLM builds. You can use the x-android-aarch64 preset and specify the NDK path to streamline the cross-compilation setup.

Deploy cross-compiled LLM binaries to an Android device using ADB push and run procedures. After building the libraries with CMake and the NDK, transfer the compiled files and models to the target hardware.

Yes, the Android LLM cross-compilation workflow supports optional building of tests and benchmarks. This allows developers to validate LLM library performance directly on AArch64 mobile targets.

Cross-compiling LLMs for Android is difficult due to toolchain setup complexities and LLM integration challenges for mobile applications. A dedicated build process addresses these by managing NDK configuration and ADB deployment steps.
