After proguard, got error when use socket for cross-process communication

Question

I use LocalSocket and LocalServerSocket for cross-process communication. my code is:

public class SocksThread extends Thread {

public static final String TAG = "SocksThread";

private File mProtect = null;

private SocksService mSocksService = null;

private volatile Boolean mIsRunning = true;
private volatile LocalServerSocket mLocalServerSocket = null;

public SocksThread(SocksService SocksService) {
    mSocksService = SocksService;
    mProtect = new File(mSocksService.getFilesDir(), SocksConfig.SHARE_PATH_PROTECT_PATH);
}

@Override
public void run() {
    mProtect.delete();

    try {
        LocalSocket localSocket = new LocalSocket();
        localSocket.bind(new LocalSocketAddress(mProtect.getAbsolutePath(), LocalSocketAddress.Namespace.FILESYSTEM));
        mLocalServerSocket = new LocalServerSocket(localSocket.getFileDescriptor());
    } catch (IOException e) {
        e.printStackTrace();
        Log.e(TAG, "unable to bind", e);

        return;
    }

    final LocalSocket socket = mLocalServerSocket.accept();
}
}

There is no problem without proguard, but when I set proguard, the following line throw error:

final LocalSocket socket = mLocalServerSocket.accept();

And the error log is:

java.io.IOException: accept failed: EBADF (Bad file descriptor)
