我想用Environment变量替换一个上下文方法.
但不确定它们是否意味着相同.

有什么区别

getFilesDir()和Environment.getDataDirectory()？

我如何data\data从data\data\com.Myapp使用中获得Environment Variable？

我是android和java编程的新手,有人可以告诉我如何保存文件,我有以下代码:

InputStream is = new FileInputStream( location + "/zipSample.zip");
ZipInputStream zis = new ZipInputStream(new BufferedInputStream(is));

try {
    ZipEntry ze;
    while ((ze = zis.getNextEntry()) != null) {
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        byte[] buffer = new byte[1024];

        int count;
        while ((count = zis.read(buffer)) != -1) {
            baos.write(buffer, 0, count);
        }

        String filename = ze.getName();
        byte[] bytes = baos.toByteArray();

        // Do something with 'filename' and 'bytes' ...
        // How do I save to sdcard?
    }
} finally {
    zis.close();
}

非常感谢您的帮助.
