DownloadManager'ı kullanarak harici depolama birimine yükleme işlemi düzgün çalışmıyor Galaxy S7

Question

Dahili depolama çalışmalarına yükleme. Ancak, dış sdcard'a indirmeyi denediğimde, durum 2 ~ 3 dakika sonrasına kadar güncellenmez. (İmleç, .getColumnIndex (DownloadManager.COLUMN_BYTES_DOWNLOADED_SO_FAR))) 'dan indirilen 0 bayt aldığım anlamına gelir;). Sonunda 2 ~ 3 dakika sonra indirir.

Ben Not 4 ve Galaxy S5 test edilmiş ve onlar iyi görünüyor diyor.

Android 6.0 olayı olabilir mi? veya S7? Bu bir hata mı? Yoksa burada yanlış yaptığım bir şey var mı? https://drive.google.com/open?id=0By...Ec1ZHk5ZWRkWWc

(ı Mp4 Numune web sitesinden URL'yi var) onun Sen gibi çalışma zamanında izinleri sormalısınız android 6. yeni izin sistemi hakkında:

if (ContextCompat.checkSelfPermission(activity, Manifest.permission.WRITE_EXTERNAL_STORAGE) != getPackageManager().PERMISSION_GRANTED){ 
       ActivityCompat.requestPermissions(activity, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, YOUR_CONST_REQUEST_CODE); 
      } 
    } 

Ve dinleyici uygulamak

@Override 
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) { 
     switch (requestCode) { 
      case YOUR_CONST_REQUEST_CODE: { 
       // If request is cancelled, the result arrays are empty. 
       if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) { 

// invoke your download method 

        } else { 
// if permissions was not granted 
        } 

       } 
      } 
    } 

Diğer yollarla hedefSdkVersion öğesini gradient dosyasından 23 daha az ayarlayabilirsiniz. "Dosya hedefi = new File (destFolder, deskFileName);"
