You can register a callback like the example below with loguru.

#include <loguru.hpp>
#include <android/log.h>

...

void android_log(void* user_data, const loguru::Message& message)
{
    const char* TAG { "TagOfYourApplication" };

    switch (message.verbosity)
    {
        case loguru::Verbosity_ERROR:
            __android_log_print(ANDROID_LOG_ERROR, TAG, "%s%s%s", message.preamble, message.prefix, message.message);
            break;
        case loguru::Verbosity_WARNING:
            __android_log_print(ANDROID_LOG_WARN, TAG, "%s%s%s", message.preamble, message.prefix, message.message);
            break;
        case loguru::Verbosity_INFO:
            __android_log_print(ANDROID_LOG_INFO, TAG, "%s%s%s", message.preamble, message.prefix, message.message);
            break;
        case loguru::Verbosity_MAX:
            __android_log_print(ANDROID_LOG_VERBOSE, TAG, "%s%s%s", message.preamble, message.prefix, message.message);
            break;
        default:
            __android_log_print(ANDROID_LOG_DEBUG, TAG, "%s%s%s", message.preamble, message.prefix, message.message);
            break;
    }
}

Register the callback function when you set up loguru in your native code:

#include <loguru.hpp>

...
// this block is optional, it allows you to configure the message preamble
loguru::g_preamble_header  = false;
loguru::g_preamble_date    = false;
loguru::g_preamble_time    = false;
loguru::g_preamble_uptime  = false;
loguru::g_preamble_thread  = true;
loguru::g_preamble_file    = true;
loguru::g_preamble_verbose = false;
loguru::g_preamble_pipe    = false;

// register your callback function
loguru::add_callback("android_logger", android_log, nullptr, loguru::Verbosity_MAX);
...
