Question

参考Using Arabic characters with google TTS API，我尝试了以下内容：

代码：

public void button_star_click(View view) 
{

    player = new MediaPlayer();
    player.setAudioStreamType(AudioManager.STREAM_MUSIC);  

    String Abc = "http://translate.google.com/translate_tts?tl=zh-cn&q=你好嗎";
    try 
    {
        player.setDataSource(Abc);
    } 
    catch (IllegalArgumentException e) {Toast.makeText(getApplicationContext(), "You might not set the URI correctly!", Toast.LENGTH_LONG).show();} 
    catch (SecurityException e) {Toast.makeText(getApplicationContext(), "You might not set the URI correctly!", Toast.LENGTH_LONG).show();} 
    catch (IllegalStateException e) {Toast.makeText(getApplicationContext(), "You might not set the URI correctly!", Toast.LENGTH_LONG).show();} 
    catch (IOException e) {e.printStackTrace();}
    try 
    {
        player.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();}
    player.start(); 
}

logcat的：

问题：

单击按钮后，不会输出任何声音。

我已经尝试了http://translate.google.com/translate_tts?tl=zh-hk&q=你好嗎，它也正常工作。

我尝试过实施TTS但似乎TTS只支持英语，德语，法语和其他2种语言，共有5种语言，只有粤语或中文。

有没有人可以告知上述代码有什么问题？ 非常感谢！
