爲什麼播放mp3強制崩潰？

Question

我使用了相同的確切代碼，但與.wav文件，它的工作 - 約50戲劇，然後它墜毀。我切換到MP3文件，他們不會玩。

程序本身的工作fine--我知道在這種情況下會出現以下錯誤：

case R.id.playButton: 
     switch (korean.getIndex()){ 
     case -1: break; // This is the case when the program first starts. 
     case 0: MediaPlayer.create(this, R.raw.c0).start(); break; 
     case 1: MediaPlayer.create(this, R.raw.c1).start(); break; 
     case 2: MediaPlayer.create(this, R.raw.c2).start(); break; 
     case 3: MediaPlayer.create(this, R.raw.c3).start(); break; 
     case 4: MediaPlayer.create(this, R.raw.c4).start(); break; 
     case 5: MediaPlayer.create(this, R.raw.c5).start(); break; 
     case 6: MediaPlayer.create(this, R.raw.c6).start(); break; 
     case 7: MediaPlayer.create(this, R.raw.c7).start(); break; 
     case 8: MediaPlayer.create(this, R.raw.c8).start(); break; 
     case 9: MediaPlayer.create(this, R.raw.c9).start(); break; 
     case 10: MediaPlayer.create(this, R.raw.c10).start(); break; 
     case 11: MediaPlayer.create(this, R.raw.c11).start(); break; 
     case 12: MediaPlayer.create(this, R.raw.c12).start(); break; 
     case 13: MediaPlayer.create(this, R.raw.c13).start(); break; 
     case 14: MediaPlayer.create(this, R.raw.v14).start(); break; 
     case 15: MediaPlayer.create(this, R.raw.v15).start(); break; 
     case 16: MediaPlayer.create(this, R.raw.v16).start(); break; 
     case 17: MediaPlayer.create(this, R.raw.v17).start(); break; 
     case 18: MediaPlayer.create(this, R.raw.v18).start(); break; 
     case 19: MediaPlayer.create(this, R.raw.v19).start(); break; 
     case 20: MediaPlayer.create(this, R.raw.v20).start(); break; 
     case 21: MediaPlayer.create(this, R.raw.v21).start(); break; 
     case 22: MediaPlayer.create(this, R.raw.v22).start(); break; 
     case 23: MediaPlayer.create(this, R.raw.v23).start(); break; 
     default: break; 
     } 

我知道這是一個lot--但這些都是靜態的方法調用，所以它應該是正常的，對不對？爲什麼會這樣崩潰？

創建的MediaPlayer對象一個又一個從未釋放資源，所以你可能耗盡內存，可以考慮：

// declare mp as class field. 
MediaPlayer mp = null; 

//... 

case R.id.playButton: 
    if (mp != null) 
     mp.release(); 
    switch (korean.getIndex()){ 
    case -1: break; // This is the case when the program first starts. 
    case 0: mp = MediaPlayer.create(this, R.raw.c0);mp.start(); break; 
    case 1: mp = MediaPlayer.create(this, R.raw.c1);mp.start(); break; 
    case 2: mp = MediaPlayer.create(this, R.raw.c2);mp.start(); break; 
    // and so on 

或者，您可以set OnCompletionListener並調用release那裏。
