以下代码似乎在 API 级别 11 及更高版本上运行良好：
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;
}
但是在运行时抛出一个IOException错误，例如 10 或 8。我想在我的应用程序中也支持这些 API，所以我需要把它带到工作中......
我检查了所有文件名、路径等。再一次，在 3.0 下它可以工作。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？？？
更新
我忘了提到我正在使用AsyncTask<Void, Void, Void>.
