Why does MediaPlayer show so much log log on Android?

Question

I am using MediaPlayer to display SplashVideo, and the log is suspiciously populated with a detailed message. This is not a mistake, but still this is not normal behavior.

Uri video = Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.logo_vid); videoHolder.setVideoURI(video); videoHolder.setOnCompletionListener(new OnCompletionListener() { public void onCompletion(MediaPlayer mp) { jumpMain(); } }); videoHolder.start(); } 

and this is a magazine ...

How I wrote my work, but I wonder if I'm doing it right.
