Configuring NAPI for Your Project-HarmonyOS App Integration-Integration-App Development-CANN

When building the NAPI of the inference model, for example, in a NPU-based scenario, you need to pack libhiai.so, libhiai_ir.so (optional), libhiai_ir_build.so (optional), libhiai_ir_build_aipp.so (optional), and libentry.so when packing the HAP, where libentry.so is the binary file for the demo packed using NAPI.

Copying .so Files of the DDK to the Project

Copy .so files of the CANN DDK to the corresponding location of the project. In the demo, the .so files are stored under the entry/libs directory.

Copying Header Files of the DDK to the Project

Copy header files of the CANN DDK to the corresponding location of the project. In the demo, the header files are stored under the entry/src/main/cpp/include directory.
