我正在尝试使用整数数组保存一些数据块覆盖范围,这些数据只是简单地保存了一个数据块的执行次数。但是,由于某些原因,当我尝试写入某些创建的文件(例如“BlockForHelper.txt”,例如我在Eclipse中制作并放置在项目目录中)时,出现此错误:Android错误 - 打开失败ENOENT

,并给我的错误:
public void blockCoverage() throws IOException
{
String coverage = "";
for (int x = 0; x < 20; x++)
coverage += x + " " + bb_count[x] + "\n";
File file = new File("/nfs/guille/groce/users/nicholsk/workspace3/SQLTest/BlockForTest.txt");
Writer out = new OutputStreamWriter(new FileOutputStream(file)); // Here
try
{
out.write(coverage);
} finally {
out.close();
}
}
任何人都知道可能会导致什么呢?
eclipse中的什么文件夹你把这个txt文件? – 2012-07-23 21:21:30
只是我的项目的根目录。为什么? – NioShobu 2012-07-23 21:25:10
我有这个问题。我删除了以编程方式创建的文件夹,并手动创建并解决了问题! – breceivemail 2013-08-24 08:30:57
