it helps some times You should look at implementing HTTP Ranges. This will allow you to re-start your download when it fails.
As to why it stops, some carriers implement download limits which will drop a connection after a certain time or download amount. I've seen this first hand on one UK carrier and been told about it on others. It's usually easy to verify the limit by trying to download the file via Androids browser and if you see it stall or stop you know it's most likely a carrier issue (and yes, the download can be terminated without throwing an Exception).

With these it helps The phone disconnects from Wi-Fi when going into sleep mode, which I guess was the cause here? Take a look at WifiManager's WifiLock to see how you can prevent it.

I think the issue was by ths following , This is no way to copy streams. It assumes too many things that may not be true.
The canonical way in Java is as follows:
code :
byte[] buffer = new byte[8192];  // or whatever you like, anything above zero. Note that it doesn't have to be the size of the file
int count;
while ((count = in.read(buffer)) > 0)
{
    out.write(buffer, 0, count);
}

it fixes the issue I am getting a list of image url from server whose count is approximately in between 400-500. How can i download this image in background into local folder of the device ? , Use below library -
code :
implementation 'com.amitshekhar.android:android-networking:1.0.2'
for (int j = 0; j < imageArrayList.size(); j++) {
        downloadImage(imageArrayList.getImagePath(j), imageArrayList.get(j),getImageName);
    }


 private void downloadImage(String imageURL, String imagename) {

    AndroidNetworking.download(imageURL, getCacheDir().getPath() + "/" + Constant.FOLDER_NAME + "/", imagename)
            .setPriority(Priority.HIGH)
            .build()
            .setDownloadProgressListener(new DownloadProgressListener() {
                @Override
                public void onProgress(long bytesDownloaded, long totalBytes) {
                    // do anything with progress
                }
            })
            .startDownload(new DownloadListener() {
                @Override
                public void onDownloadComplete() {

                    // do anything after completion


                }

                @Override
                public void onError(ANError error) {
                    // handle error

                }
            });

}
