也许我做错了，但我还没有学到其他的方法。最重要的是，我决定构建一个程序，将libOpenSLES.so(来自AndroidNDK的库)本地链接到raspberrypi4。
我的树莓派操作系统:Debian bullseye armhf.
uname基于"增大化现实"技术
Linux guardian 5.10.52-v7l + # 1441 SMP Tue Aug 3 18:11:56 BST 2021 armv7l GNU/Linux
为此，我将Android NDK中的库和头文件直接复制到我的环境中。
ls /usr/include/SLES
OpenSLES.h OpenSLES_AndroidConfiguration.h OpenSLES_Platform.h
OpenSLES_Android.h OpenSLES_AndroidMetadata.h
file /usr/lib/libOpenSLES.so
/usr/lib/libOpenSLES.so: ELF 32-bit LSB shared object, ARM, EABI5 version 1 (SYSV), dynamically linked, BuildID [md5 / uuid] = ee43a7abfd4e7dd27b03b0c97b80b768, with debug_info, not stripped
The description is the same for all other libraries in the system.
使用链接键-lOpenSLES构建的程序没有错误，但在启动时，它在加载此库时给出错误
E: [pulseaudio] ltld -bind-now.c: Failed to open module/home/pulseaudio-android/testbuild/src/.libs/module-opensles。so:libOpenSLES.so:无法打开共享目标文件:没有这样的文件或目录
同时，ldd不能正确计算
ldd /usr/lib/libOpenSLES.so非动态可执行文件
我尝试ldd为AndroidNDK中提供的所有库
find ./android-ndk-r23b -name libOpenSLES.so | grep androideabi | xargs ldd

谢谢你的帮助。
对不起，问题已被清除。Android NDK提供了仅用于链接的存根库，它们不包含任何用于执行的代码。真正的库来自真正的Android设备。
谢谢。
