问题描述

创建 MediaPlayer 实例时 LogCat 显示此错误:

QCMediaPlayer 媒体播放器不存在

QCMediaPlayer mediaplayer NOT present

为什么会这样，是否正常?

Why is that and is it normal?

示例:

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();
    }
}

推荐答案

表示您的平台不支持 QCMediaPlayer.QCMediaPlayer 提供扩展的 API 和接口，以在兼容的 Snapdragon 版本中获取和设置 DASH 协议的 MPD 属性.所以，这个错误应该不会影响正常情况下的媒体播放

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
