- I have developed app in which there are 4 sound files playing together
- First sound :
- on next button press -Second sound :
- on previous button press
- Third sound :
- plays sound of item
Fourth sound :
- plays on item (How item speaks)
Everything works well until user play back and fourth quickly, text-to-speech engine crash with
MediaPlayer: error (-19, 0) android
- i tried to reset media player , release and stop in next and previous button, but still sound of items stops after few back and fourth.
What i have done :
public class A extends Activity {
int imgArr[] = {R.drawable.a, R.drawable.b, R.drawable.c, R.drawable.d};
int soundsrc[] = {R.raw.a, R.raw.b, R.raw.c, R.raw.d};
String pro[] = new String[]{"a", "b", "c", "d"};
ImageView iView;
int count = 0;
TextToSpeech txtToSpeech1;
MediaPlayer mp;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_names);
stopService(new Intent(this, PlayMusic.class));
iView = (ImageView) findViewById(R.id.imageView5);
iView.setImageResource(R.drawable.befora);
txtToSpeech1 = new TextToSpeech(getApplicationContext(), new TextToSpeech.OnInitListener() {
@Override
public void onInit(int status) {
if(status != TextToSpeech.ERROR) {
txtToSpeech1.setLanguage(Locale.UK);
txtToSpeech1.speak(pro[count], TextToSpeech.QUEUE_FLUSH, null);
}
}
});
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
public void run() {
aSounds();
}
}, 1000);
}
@Override
public void onDestroy() {
// Don't forget to shutdown!
if (txtToSpeech1 != null) {
txtToSpeech1.stop();
txtToSpeech1.shutdown();
}
super.onDestroy();
}
public void onPause(){
if(txtToSpeech1 !=null){
txtToSpeech1.stop();
txtToSpeech1.shutdown();
}
super.onPause();
}
public void aSounds() {
mp = MediaPlayer.create(ANames.this, soundsrc[count]);
mp.start();
}
public void forwardd(View v) {
buttonSounds(R.raw.multimedia_button_click);
if (count < imgArr.length && count >= 0) {
count++;
if (count == imgArr.length)
count = 0;
iView.setImageResource(imgArr[count]);
if (txtToSpeech1.isSpeaking()) {
Log.i("Tag", "Stop speaking");
txtToSpeech1.stop();
}
txtToSpeech1.speak(pro[count], TextToSpeech.QUEUE_FLUSH, null);
// Execute some code after 2 seconds have passed
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
public void run() {
aSounds();
}
}, 1000);
}
}
public void backwardd(View v) {
buttonSounds(R.raw.multimedia_button_click);
if (count >= 0 && count < imgArr.length) {
count--;
if (count == -1) {
count = imgArr.length - 1;
}
iView.setImageResource(imgArr[count]);
txtToSpeech1.speak(pro[count], TextToSpeech.QUEUE_FLUSH, null);
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
public void run() {
aSounds();
}
}, 1000);
}
}
public void onImageClick(View v) {
txtToSpeech1.speak(pro[count], TextToSpeech.QUEUE_FLUSH, null);
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
public void run() {
aSounds();
}
}, 1000);
}
public void home(View v) {
buttonSounds(R.raw.multimedia_button_click);
Intent ii = new Intent(ANames.this, PlayMusic.class);
finish();
startService(ii);
}
public void buttonSounds(int src) {
mp = MediaPlayer.create(ANames.this, R.raw.multimedia_button_click);
mp.start();
}
}
