It's me again. Posting another question here, same as last. How do enable user input to be sent to a remote php server? I've searched through stack and some other resources and found alot of good hints. But I'm still having trouble. Since my last post I have updated my code to include an HTTP POST request imbedded into my Submit button. When I launch I get my form screen, I'm able to input info into the text fields, but when I click submit the the app stops working. For my Database I'm using Xeround. If anyone can tell what it is I'm missing that would be awesome. \[code\]package com.androidbook.john;import android.app.Activity;import android.os.Bundle;import java.io.BufferedReader;import java.io.IOException;import java.io.InputStreamReader;import java.i
