Example Cross Compile Logging for Android & iOS

[!WARNING]
This information may be out-of-date.

Add this to your header.


#include <iostream>
#include <sstream>
#define LOG_TAG "# MapLibre "
 
#ifdef __ANDROID__
  #include <android/log.h>
#endif

Then you can use this sample code which compiles for both Android & Xcode.


std::stringstream message;
 
// Set your message to log.
message << LOG_TAG << __FUNCTION__ << " req->resource.url = " << req->resource.url << std::endl;
 
// Logs to Xcode console.
std::cout << message.str();
 
#ifdef __ANDROID__
// Logs to Android Logcat.
__android_log_print(ANDROID_LOG_DEBUG, LOG_TAG, "%s", message.str().c_str());
#endif

Which will log the following samples.
