如果我在我的HTC魔术手机上运行以下代码，我得到一个java.lang.OutOfMemoryError错误。这个简单的短代码是不是要求太多，我的手机要处理？为什么我的HTC魔法会出现OutOfMemoryError异常？
我认为代码简单而且非常高效，但是我的手机根本不会吃它。 如果我将代码缩减一半（在第一个for循环之后），手机就会吃掉它。
我检查了我的手机内存，它说在“打开高级任务杀手”应用程序的帮助下有79 MB免费。
我没有很多应用程序同时打开，我试图执行的代码并不是很多要求（在我看来）。
我真的不得不购买新手机吗？还是有其他办法可以解决这个问题吗？
public class SomeActivity extends Activity
{
public TextView tv;
public ImageView imgv;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
tv = (TextView)findViewById(R.id.textview);
imgv = (ImageView)findViewById(R.id.imageView1);
tv.setText("This is the new text");
try
{
String selectedGenre = "http://www.somewebpage.com/";
Document doc = Jsoup.connect(selectedGenre).timeout(0).get();
Elements liElements = doc.select("ul#navbar li");
String pagesAmount = null;
int liElementsCounter = 0;
for (Element element : liElements)
{
if (liElementsCounter < 1 && element.html().contains("Page ("))
{
String liElementText = element.html();
pagesAmount = liElementText.substring((liElementText.indexOf("/") + 2), (liElementText.lastIndexOf(")") - 1));
liElementsCounter++;
}
}
doc = Jsoup.connect(selectedGenre.replace("p1", "p" + new Random().nextInt(1 + Integer.parseInt(pagesAmount)))).timeout(0).get();
Elements aNameElements = doc.select("a[name]");
ArrayList<String> elementsArray = new ArrayList<String>();
int elementsSize = 0;
for (Element element : aNameElements)
{
if (elementsSize % 3 == 0)
{
elementsArray.add(element.attr("href").replaceAll("\\s",""));
}
elementsSize++;
}
}
catch (Exception ex)
{
tv.setText(ex.getMessage());
System.out.println("Exception! " + ex.getMessage());
}
}
}
这只是我真的想执行的代码总量的1/15

OutOfMemoryError指的是耗尽堆内存，对于您的进程而言，最有可能为16MB，而不管设备上可用的“内存”是多少，这实际上是可用存储空间量（磁盘/闪存/任何内存）。在哪一行是错误被抛出？请包含来自logcat的堆栈跟踪。 –
