Android Volley double post when have slow request

Question

I have a problem with Volley POST request on slow network. Everytime I see BasicNetwork.logSlowRequests in my LogCat, my POST request is executed twice or more

Answer 1

The only way I got the double requests to stop was to set the retry policy retries to -1

request.setRetryPolicy(new DefaultRetryPolicy(0, -1, 0));

I think this is because the DefaultRetryPolicy's logic for attempts remaining returns true if retryCount is 0 and Max retries is also 0 in the hasAttemptRemaining() method:

protected boolean hasAttemptRemaining() {
    return this.mCurrentRetryCount <= this.mMaxNumRetries;
}
