i am creating an android application in which i want to access database from mysql for user name, phone no and email address. and i want to compare phone no from android phone contact list and the phone no getting from mysql database. for that purpose i use 2 arraylist 1st for phone contact and 2nd for mysql phone no. my main problem is when i compare both the arraylist then i shows no result. i attach here the code please someone help me to solve this problem.
and this is my php code from which i access details
Log all the values from both locations and see that they should match.
Then log what happens in each comparison: which value is being compared to which value.
When you see two things that should be equal and aren't then there is a problem that needs to be addressed. But right now we have no idea if there are no entries in one or the other list, or if they are in a different format, etc... So you need to see exactly what is being compared to narrow the problem down.
