LiteRT v2 (CompiledModel) C++ SDK for Android

You can also use prebuilt LiteRT Maven packages for your Android C++ libraries without building the entire LiteRT source tree. The integration is done with CMake.

The following shows basic steps to use LiteRT CompiledModel API in your C++ NDK code.

Integrate LiteRT C++ SDK

Choose a folder to host LiteRT C++ SDK. We'll refer to it as <litert_cc_sdk_location>.

1. Download C++ SDK

   You need to prepare the necessary files (CMakeLists.txt, source and header files) from LiteRT C++ SDK zip file under <litert_cc_sdk_location>.

   wgethttps://github.com/google-ai-edge/LiteRT/releases/download/<litert_version>/litert_cc_sdk.zip
   unziplitert_cc_sdk.zip-d<litert_cc_sdk_location>
   

2. Place libLiteRt.so from the LiteRT Maven package under <litert_cc_sdk_location>.

   cp<path_to_prebuilt_lib>/libLiteRt.so<litert_cc_sdk_location>/litert_cc_sdk/
   

3. Update your CMakeLists.txt to use LiteRT API.

   add_subdirectory("<litert_cc_sdk_location>""<litert_cc_sdk_location>/build")
   include_directories("<litert_cc_sdk_location>")
   target_link_libraries(${CMAKE_PROJECT_NAME}
   # Use `litert_cc_api` for LiteRT C++ SDK
   litert_cc_api
   android
   log)
   

4. Update your build.gradle.kts to configure LiteRT C++ SDK.

    externalNativeBuild {
    cmake {
    path = file("<litert_cc_sdk_location>/CMakeLists.txt")
    version = "3.22.1"
    }
    }
