How do I use this project in Logcat for Android?

[djhdj1]

I want to apply this library to Android and make it available on logcat, how should I do it? Thank you very much!!

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);
...
