Question

使用setDataSource将Uri源放入MediaPlayer的对象时出现IOException错误。尝试使用

从移动设备获取歌曲

Intent intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Audio.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent, 10);

onActivityResult

 @Override
        protected void onActivityResult(int requestCode, int resultCode, Intent data) {

            if(resultCode == RESULT_OK && requestCode == 10){
                Uri uriSound=data.getData();
                Toast.makeText(getApplicationContext(),"It Came Here",Toast.LENGTH_SHORT).show();
                play_sound(uriSound);
            }
        }

play_sound

private void play_sound( Uri uri) {


             Toast.makeText(getApplicationContext(),"It Came Here 2" + uri,Toast.LENGTH_LONG).show();

            MediaPlayer mp = new MediaPlayer();

            try {

                mp.setDataSource(getApplicationContext(), uri);
                mp.start();
            } catch (IllegalArgumentException e) {

                Toast.makeText(getApplicationContext(),"Error 1",Toast.LENGTH_LONG).show();
                e.printStackTrace();
            } catch (SecurityException e) {
                Toast.makeText(getApplicationContext(),"Error 2",Toast.LENGTH_LONG).show();
                e.printStackTrace();
            } catch (IllegalStateException e) {
                Toast.makeText(getApplicationContext(),"Error 3",Toast.LENGTH_LONG).show();
                e.printStackTrace();
            } catch (IOException e) {
                Toast.makeText(getApplicationContext(),"Error 4",Toast.LENGTH_LONG).show();
                e.printStackTrace();
            }

        }

我使用Toast检查错误位置。

错误输入＆＃34; IOException e＆＃34;我不知道谷歌搜索它是什么它我得到的是它是什么样的＆＃34;文件格式＆＃34;选定文件的问题。

解决!!只需在播放声音中添加一行

 mP.setAudioStreamType(AudioManager.STREAM_MUSIC);

Play_Sound（Uri uri）：

private void Play_Sound(Uri uri)
        {
            MediaPlayer mPlayer = new MediaPlayer();
            mPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
            try {
                mPlayer.setDataSource(getApplicationContext(), uri);
            } catch (IllegalArgumentException e) {
                Toast.makeText(getApplicationContext(), "You might 1 not set the URI correctly!", Toast.LENGTH_LONG).show();
            } catch (SecurityException e) {
                Toast.makeText(getApplicationContext(), "You might 2 not set the URI correctly!", Toast.LENGTH_LONG).show();
            } catch (IllegalStateException e) {
                Toast.makeText(getApplicationContext(), "You might 3 not set the URI correctly!", Toast.LENGTH_LONG).show();
            } catch (IOException e) {
                Toast.makeText(getApplicationContext(), "You might 4 not set the URI correctly!", Toast.LENGTH_LONG).show();

                e.printStackTrace();
            }
            try {
                mPlayer.prepare();
            } catch (IllegalStateException e) {
                Toast.makeText(getApplicationContext(), "You might not set the URI correctly!", Toast.LENGTH_LONG).show();
            } catch (IOException e) {
                Toast.makeText(getApplicationContext(), "You might not set the URI correctly!", Toast.LENGTH_LONG).show();
            }
            mPlayer.start();
        }

在媒体播放器中放置Uri源时出现IOException错误（setDataSource）
