Maybe you should first explain what you are trying to do... instead of posting some chuncks of code and let us guess about the purpose of the code

Hi

This is a login system for android.
It uses php, json e android.

Now the undefined index is resolved but i have other issues and i don't know why.

My php is this one after correcting the undefined index





And the error


The Json parse doesn't work....

But which json is invalid? I assume the var_dump of the user.

No

var_dump($user); prints the following data:



so the query works, the problem is here, response variable seem to be empty...because i don't receive any data in android app

Thank you

Based on the exception message Value array(6) of type java.lang.String cannot be converted to JSONObject, it seems to be about the var_dump of user, that's an array of 6 elements (and not a json object)

The var_dump was just to check the values, if i remove it i get this error in android app




org.json.JSONException: No value for user

So....i'm lost

And how does the json-object looks like that you are returning?

Does your php code returns this json?

That explains your error, because there is no user in the json-string and you try to retrieve the "user" key as a JSONObject.
