失敗的聯編程序事務處理文本文件

Question

我必須從96000字節的文本文件中讀取一些數據，以便我可以繪製一條線圖。我試圖讀取每2個字節，並結合他們在2個字節，然後我做了8個數組6000每個整數。但我有提到的錯誤！ 如果我嘗試只使用1,2或3陣列它的工作原理，但從4陣列不

有人可以幫助我，請看看我做錯了。 我從昨天的不同討論中讀到，並沒有真正看到任何合適的答案。 我得到的是這是內存/堆的問題。

這裏是我的代碼。

byte LSB;

這裏是我的MainActivity

public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 
     Button strt = (Button) findViewById(R.id.LineGraph); 

     strt.setOnClickListener(new View.OnClickListener() { 

      @Override 
      public void onClick(View v) { 
       lineGraph line = new lineGraph(); 

       Intent lineIntent = null; 
       try { 
        lineIntent = line.getIntent(getBaseContext()); 
       } catch (IOException e) { 
        // TODO Auto-generated catch block 
        e.printStackTrace(); 
       } 


       startActivity(lineIntent); 

      } 
     }); 
    } 

我logcat中給出了下面的輸出：

想不出這樣做的方式..

for(i=0;i<12000;i=i+2){ y1[j]= current; j++; } 
TimeSeries series1 = new TimeSeries("line1"); 
for(int k=0;k<x.length;k++){ series1.add(x[k], y1[k]); } 
for(i=12000;i<24000;i=i+2){ y1[j]= current; j++; }
