Answer 1

Android MediaPlayer est gourmand en ressources. Si vous ne nettoyez pas MadiaPlayer après l'avoir utilisé, votre application ne peut lire qu'une douzaine de fichiers audio ou vidéo ou moins. Comme la référence de MediaPlayer est une variable locale, elle ne peut pas être nettoyée.

Changez votre référence mediaPlayer en valeur déposée Libérez votre mediaPlayer après utilisation. (En utilisant onCompleteListener par exemple) N'oubliez pas de libérer lorsque votre contexte est détruit. (Activité, service .. etc)

public void playthree(View view) 
{ 
    int id = view.getId(); 
    Log.i("ID", "ID value is " + id); 

    MediaPlayer mediaPlayer = MediaPlayer.create(this,R.raw.three); 
    mediaPlayer.start(); 
    // mediaPlayer can not be released. 
}
