У меня есть приложение для загрузки zip-файла и сохранения на SDCard.Но я получаю zipentry=null
при чтении входного потока, он не входит в блок while.Может ли кто-нибудь помочь мне в решении этой проблемы, пожалуйста?
try {
// fileInputStream = new InputStream(input);
ZipInputStream zipInputStream
= new ZipInputStream(new BufferedInputStream(input));
ZipEntry zipEntry=zipInputStream.getNextEntry();
Toast.makeText(getApplicationContext(), "I have entered try block zipentry"+zipEntry,Toast.LENGTH_LONG).show();
System.out.println("Zipentry is"+zipEntry);
while ((zipEntry = zipInputStream.getNextEntry()) != null){
Toast.makeText(getApplicationContext(), "Entered into while block",Toast.LENGTH_LONG).show();
String zipEntryName = zipEntry.getName();
File file = new File(to + zipEntryName);
if (file.exists()){
} else {
if(zipEntry.isDirectory()){
file.mkdirs();
}else{
byte buffer[] = new byte[BUFFER_SIZE];
FileOutputStream fileOutputStream = new FileOutputStream(file);
bufferedOutputStream
= new BufferedOutputStream(fileOutputStream, BUFFER_SIZE);
int count;
while ((count
= zipInputStream.read(buffer, 0, BUFFER_SIZE)) != -1) {
bufferedOutputStream.write(buffer, 0, count);
}
bufferedOutputStream.flush();
bufferedOutputStream.close();
}
}
zipInputStream.close();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
Toast.makeText(getApplicationContext(), "File not found",Toast.LENGTH_LONG).show();
e.printStackTrace();
}catch (IOException e) {
// TODO Auto-generated catch block
Toast.makeText(getApplicationContext(), "Input outout error",Toast.LENGTH_LONG).show();
e.printStackTrace();
}
