Android OkHttp InputStream java.IOException.closed

Question

I use a OkHttpClient to download a database on the server and to copy it on my Android application, the request is ok and I get the good content.

However when I try to write my byteStream to my file I get a java.IOException.closed. Do you know what I am doing wrong ?

Response httpResponse = webApiClient.execute(
    new WebApiRequest(WebApiMethod.DB_DOWNLOAD), context);

if (httpResponse.code() == 200)
{
    try 
    {
        InputStream inputStream = httpResponse.body().byteStream();
        File databasePath = context.getDatabasePath(Constant.DATABASE_NAME);
        FileOutputStream output = new FileOutputStream(databasePath);
        int bufferSize = 1024;
        byte[] buffer = new byte[bufferSize];
        int len;
        while ((len = inputStream.read(buffer)) != -1)
        {
            output.write(buffer, 0, len);
        }
        success = true;
    }
    catch (Exception exc)
    {
        Utils.DisplayException(exc, context);
    }
}

I also tried to read my ByteStream with a BufferedSink but the result was the same

BufferedSink sink = Okio.buffer(Okio.sink(databasePath));
sink.writeAll(httpResponse.body().source());
sink.close();

Answer 1

I find why the stream was closed, for some test, I was checking the content of my output String with a System.out.println, but when you read or print the output it close automatically the stream, this is why I get an error.

In conclusion, One thing to remember with stream : Reading or printing the outputStream will close it.
