Android 5.0设备检查当前下载文件大小

Question

如果设备不足5.0，我有这个代码可以精确检查下载文件的当前大小。

例如：我的下载文件是200MB，在下载时我检查文件路径和文件大小＆lt; 200MB。

但是从5.0开始它返回文件的整个大小，它总是返回200MB所以我无法将进度设置为进度条。请帮帮我。

filesize = Integer.parseInt(String.valueOf(file.length() / 1024));                                                      

Answer 1

Because this is the mechanism of Android 5.0. So I decided to change the way to get the current downloading file size by this code:

currentSize=cursorCheckCurrentSize.getInt(cursor.getColumnIndex(DownloadManager.COLUMN_BYTES_DOWNLOADED_SO_FAR));

It will return the bytes downloaded of the downloading file and I can play around with the result
