I am implementing an application which used to play an audio file (output from Text to speech and stored in mnt/sdcard/audiofiles/audio.mp3). When I try to play this using MediaPlayer I get an error.
Code:
MediaPlayer mMediaPlayer = new MediaPlayer();
try {
mMediaPlayer.setDataSource("/mnt/sdcard/audiofiles/audio01.mp3");
mMediaPlayer.prepare();
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
mMediaPlayer.start();
Error:

Edit 1:
This is the total code I am trying, When button1 clicked I creating an audio file. I checked for the file using DDMS->File Exploring and saved it to my desktop and played. It is working fine. But when I try to access it pragmatically and try to play I got the error.

mMediaPlayer.start();
}
else {
Log.v("MainActivity", "error saving wav file : "+i);
}
}
}
}
Edit2:
I tried with the following code, still I am getting same error.
class MySpeech implements OnInitListener
{
String tts;
public MySpeech(String tts)
{
this.tts = tts;
mTts = new TextToSpeech(MainActivity.this, this);
}
public void onInit(int status)
{
Log.d("MainActivity", "onInit() called");
int i = mTts.synthesizeToFile(speakTextTxt, myHashRender, tempDestFile);
if(i == TextToSpeech.SUCCESS)
{
Toast toast = Toast.makeText(MainActivity.this, "Saved "+i, Toast.LENGTH_SHORT);
toast.show();
try
{
audioPlayer("mnt/sdcard/audiofiles" , "audio01.mp3"); // your file location
}
catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
else {
Log.v("MainActivity", "error saving wav file : "+i);
}
}
}
public void audioPlayer(String path, String fileName) throws IOException
{
if (mp != null)
{ System.out.println("before mp.reset() ");
mp.reset();
System.out.println("after mp.reset() ");
}
try
{
System.out.println("after path fileName ");
mp.setDataSource(path+"/"+fileName);
System.out.println("after path fileName ");
}
catch (IllegalArgumentException e)
{
// TODO Auto-generated catch block
//mp.reset();
System.out.println("IllegalArgumentException ");
e.printStackTrace();
}
catch (IllegalStateException e)
{
// TODO Auto-generated catch block
System.out.println("IllegalStateException ");
e.printStackTrace();
}
catch (IOException e)
{
// TODO Auto-generated catch block
System.out.println("IOException ");
e.printStackTrace();
}
try
{
mp.prepare();
} catch (IllegalStateException e)
{
// TODO Auto-generated catch block
System.out.println("On prepare ");
e.printStackTrace();
}
System.out.println("Before starting");
mp.start();
}
Try out playing your file using the below method.
EDITED:
Check the Link HERE it will guide you for how to implement Text to Speech – Implementing pause and resume in TTS using MediaPlayer .
I hope it will help you..
Thanks.
