解决方案

  prepare失败：状态为0x1
 

是因为无论文件路径存在的是错误的或不正确的目录或URL或URI找到。

尝试在code以下。

  mediaplayer.setDataSrouce（MainActivity.this，Uri.parse（android.resource：//com.example.lvm/raw/+名））;
 //没有任何扩展添加到名称，例如。 `R.raw.your_raw_file`
 

而不是

的

  mp.setDataSource（android.resource：//com.example.lvm/raw/+姓名）;
 

I am trying to play audio file from res/raw folder.
but getting the error
prepare failed: status = 0x1

My code:

package com.example.lvm;

import java.io.IOException;

import android.media.MediaPlayer;
import android.media.MediaPlayer.OnCompletionListener;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;

public class MainActivity extends Activity {
Button introAudio;
        @Override
        protected void onCreate(Bundle savedInstanceState) {
                super.onCreate(savedInstanceState);
                setContentView(R.layout.activity_main);
                introAudio=(Button)findViewById(R.id.introAudio);
                introAudio.setOnClickListener(new OnClickListener() {

                        @Override
                        public void onClick(View arg0) {
                                MediaPlayer mp = new MediaPlayer();
                                String name = "greeting";
                                 mp.setOnCompletionListener(new OnCompletionListener() {

                                        @Override
                                        public void onCompletion(MediaPlayer mp) {
                                            mp.release();
                                        }

                                    });

                                try {
                                     mp.setDataSource("android.resource://com.example.lvm/raw/"+name);
                                         mp.prepare();
                                         mp.start();
                                } catch (Exception e) {
                                         Toast.makeText(MainActivity.this, e.getMessage(), Toast.LENGTH_LONG).show();
                                }
                        }
                });
        }

        @Override
        public boolean onCreateOptionsMenu(Menu menu) {
                // Inflate the menu; this adds items to the action bar if it is present.
                getMenuInflater().inflate(R.menu.activity_main, menu);
                return true;
        }

}

解决方案

prepare failed:status 0x1

is occuring because of either file path is in error or incorrect directory or Url or Uri found.

Try following in your code.

 mediaplayer.setDataSrouce(MainActivity.this, Uri.parse("android.resource://com.example.lvm/raw/"+name)); 
 //do not add any extension to name, eg. `R.raw.your_raw_file` 

Instead of

mp.setDataSource("android.resource://com.example.lvm/raw/"+name);
