流媒體或從應用程序內的在線網址播放MP3

Question

您好我需要從谷歌的texttospeech API在here播放MP3文件。但我無法弄清楚如何做到這一點，這裏是我嘗試過的代碼，但沒有工作。

String url = "http://translate.google.com/translate_tts?tl=en&q="+URLEncoder.encode(home)+URLEncoder.encode(scores[0])+ 
     URLEncoder.encode(away)+URLEncoder.encode(scores[1]); 

    player = new MediaPlayer(); 
    try { 
     BufferedInputStream bis = new BufferedInputStream(new java.net.URL(url).openStream()); 
     FileOutputStream fos = new FileOutputStream("/sdcard/tts_google.mp3"); 
     BufferedOutputStream bos = new BufferedOutputStream(fos,1024); 
     byte [] data = new byte[1024]; 

     int x=0; 
     while((x=bis.read(data,0,1024))>=0){ 
      bos.write(data,0,x);    
     } 
     player.reset(); 
     player.start(); 

    } catch (MalformedURLException e1) { 
     // TODO Auto-generated catch block 
     e1.printStackTrace(); 
    } catch (IOException e1) { 
     // TODO Auto-generated catch block 
     e1.printStackTrace(); 
    } 

此人給錯誤

05-11 14:04:12.967: ERROR/MediaPlayer(20055): start called in state 1 
05-11 14:04:12.967: ERROR/MediaPlayer(20055): error (-38, 0) 
05-11 14:04:12.967: DEBUG/MediaPlayer(20055): start() out 
05-11 14:04:12.997: ERROR/MediaPlayer(20055): Error (-38,0) 

這裏是我試過

httpClient = new DefaultHttpClient(); 
    handler = new BasicResponseHandler(); 
    httpGet = new HttpGet(url); 

    try { 

     String response = httpClient.execute(httpGet,handler); 
     Log.d("SCORODROID", response); 

     File mp3File = File.createTempFile("tts_result",".mp3"); 
     FileOutputStream fos = new FileOutputStream(mp3File); 
     fos.write(response.getBytes()); 

     FileInputStream fis = new FileInputStream(mp3File); 
     player.setDataSource(fis.getFD()); 

     player.prepare(); 
     player.start(); 

    } catch (ClientProtocolException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } catch (IOException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } 

第二碼

這其中也給出了錯誤

無代碼樣品工作的方式可以喲你能幫我解決這個問題嗎？

Answer 1

你確定你從那裏得到一個MP3嗎？你檢查了答覆嗎？例如，在控制檯中使用wget會給我403錯誤，雖然它在該URL的瀏覽器中工作。所以Google可能會阻止這樣的請求（即不是源自瀏覽器）。如果您只想使用TTS，請嘗試使用integrated TTS engine。
