getNextEntry（）在3.0（API11）以下的Android版本上抛出IOException

以下代码在API级别11及更高级别上似乎运行良好：

   private ZipInputStream getFileFromZip(InputStream zipFileStream) throws FileNotFoundException, IOException {
     ZipInputStream zis = new ZipInputStream(zipFileStream);
     ZipEntry ze = null;
     while ((ze = zis.getNextEntry()) != null) {
       Log.w(ACTIVITY_LOG_TAG, "extracting file: '" + ze.getName() + "'...");
       return zis;
     }
     return null;
    }

但在以下情况下运行时会引发

IOException

，例如10或8。我想在我的应用程序中也支持这些API，所以我需要让它发挥作用

我检查了所有的文件名、路径等，再次在3.0下运行。 我也在使用actionbarsherlock，尽管这不会影响zip输入流

有人有什么想法吗

使现代化 我忘了提到我正在使用

AsyncTask

进行此操作

您能发布完整的日志吗？您提供的代码片段应该在所有android版本上运行，并添加错误输出，它与您的问题有何关系？第一个logcat（大约一半）显示了我抛出的SQLiteException。当ZipInputStream在解压DB时得到IOException时，就会发生这种情况。这并不是发生在11以上的所有API级别上。对于API级别10及以下的情况，它始终失败。
