Answer 1

what i can see, in your java code, you are sending http-param username but in your PHP page you are reading param name user $_REQUEST['user'] i think this may cause an issue... it will be like NULL in php ?

try to use same name on both Java and PHP you need to change the line in android as below

nameValuePairs.add(new BasicNameValuePair("user",abdu));
