Using LD_PRELOAD in Android

I am trying to use LD_PRELOAD to dynamically load a .so file during application launch. I built the native library using Android Studio (creating a native project and then extracting the .so file from the apk).

I followed the steps in (https://cedricvb.be/post/intercepting-android-native-library-calls/) to configure setprop but when I launched the application, the white screen appears and seems to hang but my constructor code did not get called (print a line to logcat).

I modified the simple constructor code from (https://www.gamedev.net/forums/topic/213849-linux-gt-so-files-entry-point/).

#include <jni.h>
#include <string>
#include <unistd.h>
#include <android/log.h>
#include <fcntl.h>
#include <dirent.h>
#include <dlfcn.h>

void simpleConstructor() __attribute__((constructor));
void simpleConstructor()
{
    __android_log_print(ANDROID_LOG_DEBUG,"constructor","constructor_code");
}

I configured the LD_PRELOAD variable as such

setprop wrap.com.x.y.z LD_PRELOAD=/data/local/tmp/libnative-lib.so

and the value is there when I ran getprop.

All I see in logcat are entries such as

04-07 18:03:54.850  1659  6548 I ActivityManager: Force stopping com.x.y.z appid=10209 user=0: from pid 9076

Appreciate any advice.
