在android中获取文件大小的问题[重复]

Question

此代码不适用于我。

long length = file.length();
length = length/1024;

还有其他获取文件大小的方法吗？

Answer 1

File file =new File("//data/data/Your-Application-Package-Name/File/your-file-name"); double bytes = file.length(); double kilobytes = (bytes / 1024); double megabytes = (kilobytes / 1024);Log.d("file size","size of file in KB:"+kilobytes); Log.d("file size","size of file in MB:"+megabytes);
