getFile方法使用奇怪的错误代码（1000）调用错误回调 - 尽管该文件存在

Question

window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function(fileSystem){
  fileSystem.root.getFile(localPath, { create: false }, function(fileEntry) {
      doSomethingGood();
  }, function(err) {
      alert(err.code);
  });
});

localPath中指定的文件存在于我的Filesystem中。我仍然得到错误回调。它会警告代码：1000。这很奇怪，因为根据dcoumentation，错误代码应该是FileError中等于1到12（http://cordova.apache.org/docs/en/2.5.0/cordova_file_file.md.html#FileError）的错误代码之一。那么错误代码1000想要告诉我什么？如果文件存在，为什么会抛出错误回调？

Answer 1

代码1000似乎用于无效地址。

查看以下示例（从我的日志文件中提取，在Android设备上）：
