我正在使用ARPI13项目：
https://github.com/snappautomotive/firmware_rpi-local_manifests/tree/arpi-13
JNI库似乎放在了正确的位置：
rpi4:/ # cat vendor/etc/public.libraries.txt
libjavanativetestservice_jni.so
rpi4:/ # ls -l vendor/lib64/libjavanativetestservice_jni.so
-rw-r--r-- 1 root root 10952 2023-05-29 15:40 vendor/lib64/libjavanativetestservice_jni.so
完整的代码在GitHub上：https://github.com/alvenan/aosp_bench/tree/main/bench_test_jni
设备的makefile设置如下：
PRODUCT_PACKAGES += JavaNativeTestService
PRODUCT_COPY_FILES +=
vendor/alvenan/aosp_bench/bench_test_jni/public.libraries.txt:$(TARGET_COPY_OUT_VENDOR)/etc/public.libraries.txt
英文:
I am trying create a Service that access a JNI shared library, but when it tries to access the lib it returns an exception.

I am using the ARPI13 project:
https://github.com/snappautomotive/firmware_rpi-local_manifests/tree/arpi-13
The JNI lib seems to be in the right place:
rpi4:/ # cat vendor/etc/public.libraries.txt
libjavanativetestservice_jni.so
rpi4:/ # ls -l vendor/lib64/libjavanativetestservice_jni.so
-rw-r--r-- 1 root root 10952 2023-05-29 15:40 vendor/lib64/libjavanativetestservice_jni.so
The full code is on github: https://github.com/alvenan/aosp_bench/tree/main/bench_test_jni
The device makefile has the following setup:
PRODUCT_PACKAGES += JavaNativeTestService
PRODUCT_COPY_FILES += \
vendor/alvenan/aosp_bench/bench_test_jni/public.libraries.txt:$(TARGET_COPY_OUT_VENDOR)/etc/public.libraries.txt
