Android 3.x + Java ZipFile类 - 无法从大文件中读取ZipEntries

Question

如果我通过ZipFile类打开一个大的zip文件(250MB)并尝试读取条目.这在2.x模拟器和真实硬件中工作正常.如果我在我的平板电脑(运行4.0.3的华硕Transformer)或模拟器(3.2)上使用完全一些代码,我无法读取任何条目.ZipFile类的size()函数始终返回零,ZipFile不返回任何zip条目.即使我平板电脑上的ROM附带的拉链应用程序也无法读取任何条目.zip文件没有损坏.我检查了一下.

从ZipFile读取的代码适用于所有版本较小的zip文件.2.x和3.x/4.x之间发生了什么变化？

我的Testfile是来自HighVoltage Sid Collection的C64Music.zip.它包含超过40.000个文件,大约250MB.

我不知道在哪里看.

    public class Compress { 

  private static final int BUFFER = 2048;  
  private String[] _files; 
  private String _zipFile;  
  public Compress(String[] files, String zipFile) { 
    _files = files; 
    _zipFile = zipFile; 
  }  
  public void zip() { 
    try  { 
      BufferedInputStream origin = null; 
      FileOutputStream dest = new FileOutputStream(_zipFile);  
      ZipOutputStream out = new ZipOutputStream(new BufferedOutputStream(dest)); 
      byte data[] = new byte[BUFFER]; 
      for(int i=0; i < _files.length; i++) { 
        Log.v("Compress", "Adding: " + _files[i]); 
        FileInputStream fi = new FileInputStream(_files[i]); 
        origin = new BufferedInputStream(fi, BUFFER); 
        ZipEntry entry = new ZipEntry(_files[i].substring(_files[i].lastIndexOf("/") + 1)); 
        out.putNextEntry(entry); 
        int count; 
        while ((count = origin.read(data, 0, BUFFER)) != -1) { 
          out.write(data, 0, count); 
        } 
        origin.close(); 
      } 

      out.close(); 
    } catch(Exception e) { 
      e.printStackTrace(); 
    } 

  } 

}

Call Compress like given below where you want to zip a file  :----

String zipFilePath = "fileName.zip";
File zipFile = new File(zipFilePath);
String[] files = new String[] {"/sdcard/fileName"};
if(!zipFile.exists()){
    new Compress(files, zipFilePath).zip();
   }
