Android應用程式上的Java空指針異常錯誤

Question

---你們比我聰明！！！

我無法解決此錯誤。 我的應用程序由於空指針異常而崩潰。

這是錯誤：

Gere是我要拔頭發的地方：相同的代碼可在其他收音機上使用，並且不會崩潰！！！

有任何想法嗎？？？

這是代碼：

  audioTitle.setText(infos[0]);
  listenerNomber.setText("" + getResources().getString(R.string.lable_listiner_nomber)+": " + infos[0]);
  audioTotalTime.setText(infos[5] + "k");
  if(!infos[6].equals(stationOldAudioTitle)){
      ((MiraathRadio)getApplication()).intNotification(stationTitle.getText(), stationTitle.getText(), infos[6], stationIndex);
      stationOldAudioTitle = infos[6];
  }

這是playerserver.class文件中的代碼：

stationURL = intent.getStringExtra("stationURL");
stationName = intent.getStringExtra("stationName");
stationIndex = intent.getIntExtra("stationIndex",0);
CharSequence stationAudioTitle = intent.getStringExtra("stationAudioTitle"); 

更新：我忘了提到所有這些功能中的一個鍵：當我由於異常而在彈出的系統對話框中不按OK時，該應用程序將繼續在后台運行。 只有當我單擊“確定”時，應用程序才會崩潰並關閉。

Answer 1

我不知道在哪里初始化infos ，但是基於異常（ java.lang.ArrayIndexOutOfBoundsException: length=6; index=6 ），它的長度為6，因此infos[6]不在數組范圍內。
