A question using shared library(.so) on the system app

[Onesang You]

Hello,

I am currently developing using a shared library(.so) from a system app (frameworks/base/packages/SystemUI).

However, there is a problem using the shared library(.so) that the system app cannot find lib.so file.

Is there any advice using the shared library(.so) or any additional steps that i missed? 

Current android os version is android-11.0.0_r27

cc_prebuilt_library_shared {
  name: "libmy",
  target: {
    android_arm: {
      srcs: ["libs/libmy.so"],
    },
  android_arm64: {
      srcs: ["libs/libmy.so"],
    },

  },
  shared_libs: ["libc", "libdl"],
  strip: {
    none:true,
  },
}

android_app {
  name: "SystemUI",
  ...
  required: ["privapp_whitelist_com.android.systemui", "libmy"],
  ...
}
