Fast-android-networking: ProtocolException while downloading large files.

[ExploiTR]

After fixing the OutOfMemory issue when a large file is downloaded, everything was fine.

But, suddenly found this when I tried files with size more than 40mb. It's working fine for 15-20 MB files.

09-23 22:08:38.716 18289-18289/sample.app W/System.err: com.androidnetworking.error.ANError: com.androidnetworking.error.ANError: java.net.ProtocolException: unexpected end of stream
09-23 22:08:38.721 18289-18289/sample.app  W/System.err: Caused by: com.androidnetworking.error.ANError: java.net.ProtocolException: unexpected end of stream

Can't understand what's happening.

The File was, THIS
[Exe/45mb]

[EDIT] Later I've got some more :

Checking the issue.
Have you enabled the logging?
Also refer this issue.

Enabled, Today I've tried a bigger(~60mb) file 3 times, found it working fine. Just confused what's happening.

[amitshekhariitbhu]

once disable the logging and try it out.

[ExploiTR]

Okay: From okhttp3.internal.http1

/** An HTTP body with a fixed length specified in advance. */
  private class FixedLengthSource extends AbstractSource {
    private long bytesRemaining;

    public FixedLengthSource(long length) throws IOException {
      bytesRemaining = length;
      if (bytesRemaining == 0) {
        endOfInput(true);
      }
    }

    @Override public long read(Buffer sink, long byteCount) throws IOException {
      if (byteCount < 0) throw new IllegalArgumentException("byteCount < 0: " + byteCount);
      if (closed) throw new IllegalStateException("closed");
      if (bytesRemaining == 0) return -1;

      long read = source.read(sink, Math.min(bytesRemaining, byteCount));
      if (read == -1) {
        endOfInput(false); // The server didn't supply the promised content length.
        throw new ProtocolException("unexpected end of stream");
      }

I just want to know if there is any way to ignore error caused from The server didn't supply the promised content length.

_I just want to download what the server supplies, not exactly what he tells._

Please help, @amitshekhariitbhu

[amitshekhariitbhu]

@ExploiTR I will try it.

Many thanks.

Just comment out the bellow code or off the debug. It works for me

//if (BuildConfig.DEBUG) {
// AndroidNetworking.enableLogging(HttpLoggingInterceptor.Level.BODY)
// }/
