解决方案

这意味着你的平台不支持QCMediaPlayer。 QCMediaPlayer提供了扩展的API和接口，以获取和设置兼容的Snapdragon DASH协议是建立MPD属性。因此，这个错误不应该对媒体在正常情况下玩影响

When creating an instance of MediaPlayer LogCat shows this error:

QCMediaPlayer mediaplayer NOT present

Why is that and is it normal?

Sample:

package com.example.testapp;

import android.app.Activity;
import android.media.MediaPlayer;
import android.os.Bundle;



public class MainActivity extends Activity{


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        MediaPlayer mediaPlayer = new MediaPlayer();
    }
}

It means your platform does not support QCMediaPlayer. QCMediaPlayer provides extended APIs and interfaces to get and set MPD attributes for DASH protocol in compatible Snapdragon builds. So, this error should not affect on media playing in normal case
