我正在下載一些.zip文件,雖然當我嘗試解壓縮它們時,我得到「數據錯誤」。現在我去看到下載的文件,並且它們比原版的。這可能是錯誤的原因嗎?文件下載代碼下載文件比原來大
代碼下載文件:
URL=intent.getStringExtra("DownloadService_URL");
FileName=intent.getStringExtra("DownloadService_FILENAME");
Path=intent.getStringExtra("DownloadService_PATH");
try{
URL url = new URL(URL);
URLConnection conexion = url.openConnection();
conexion.connect();
int lenghtOfFile = conexion.getContentLength();
lenghtOfFile/=100;
InputStream input = new BufferedInputStream(url.openStream());
OutputStream output = new FileOutputStream(Path+FileName);
byte data[] = new byte[1024];
long total = 0;
int count = 0;
while ((count = input.read(data)) != -1) {
output.write(data);
total += count;
notification.setLatestEventInfo(context, contentTitle, "Starting download " + FileName + " " + (total/lenghtOfFile), contentIntent);
mNotificationManager.notify(1, notification);
}
output.flush();
output.close();
input.close();
代碼解壓:
try {
String zipFile = Path + FileName;
FileInputStream fin = new FileInputStream(zipFile);
ZipInputStream zin = new ZipInputStream(fin);
ZipEntry ze = null;
while ((ze = zin.getNextEntry()) != null) {
UnzipCounter++;
if (ze.isDirectory()) {
dirChecker(ze.getName());
} else {
FileOutputStream fout = new FileOutputStream(Path
+ ze.getName());
while ((Unziplength = zin.read(Unzipbuffer)) > 0) {
fout.write(Unzipbuffer, 0, Unziplength);
}
zin.closeEntry();
fout.close();
}
}
zin.close();
File f = new File(zipFile);
f.delete();
notification.setLatestEventInfo(context, contentTitle, "File successfully downloaded", contentIntent);
mNotificationManager.notify(1, notification);
} catch (Exception e) {
notification.setLatestEventInfo(context, contentTitle, "Problem in downloading file ", contentIntent);
mNotificationManager.notify(1, notification);
}
}
的解壓proccess啓動,但與錯誤提取一些文件後停止。我試圖anothe [R .zip文件我得到了CRC失敗的錯誤..我測試了兩個.zip文件與winrar ..
原始文件大小:3.67mb ..下載文件大小:3.93mb
你能告訴我如何解決這些問題 – Omar
用'output.write(data,0,count)'替換'output.write(data)'。 –
