  • 0

I’m using eclipse to develo[p an Android app. the app sends the user name and password to the php (server side), if the user doesn’t exists it returns “not found”….

for now I don’t want to use json 🙂

my problem is that i can’t do EQUAL to the retur string !!!! it’s not working

if(text=="not found") ShowMessage("Invalid user and password !!");

or 

if(text==getResources().getString(R.string.wronguser))
    ShowMessage("Invalid user and password !!");

and I tried the .equal(..) function BUT it’s not work….

When I assign the return vale to textview it show me “not found” so why the == OR .equal doesn’t work????

My php using UTF-8 encoding…THANX 🙂

    In Java strings should be compared using .equals. (== performs an identity comparison, while .equals compares actual content.)

    So start by changing

    if (text=="not found") ...

    to

    if (text.equals("not found")) ...

    etc.

    If that doesn’t seem to work, make sure the strings doesn’t contain unexpected leading / trailing white-space. You may also want to ignore case:

    if (text.trim().equalsIgnoreCase("not found")) ...
