Are Log messages and System.out.println calls visible once an Android app is published?

I have many calls to Log.d() and System.out.println(), which I have used for debugging, in my Android application. Are these log messages still visible to anyone who runs the production apk?

All Log messages still visible to anyone who runs the production apk so you can create a custom class for print all the Log

public class MyLog {
     public final boolean ENABLE_LOG = true; // or ENABLE_LOG = BuildConfig.DEBUG

     public static void d(String tag, String msg) {
        if (ENABLE_LOG){
            Log.d(tag, msg);
        } 
     }
     public static void e(String tag, String msg){
        ...
     } 
     ...
}

and use

 MyLog.d("TAG","test"); // instead of Log.d("TAG","test")

Yes. it is visible to others and retrievable using tools. You can pro grammatically check if it is in debug mode by following code,

 if (BuildConfig.DEBUG) {
    Log.d(TAG, "xxxx");
 }

Thank you

Yes, all log messages are still logged into standard Android logcat, even in release builds.
