JSON returning html

I'm returning a JSON from a server using PHP with the simple code:

<?php
$response = array();
$response["success"] = 1;
echo json_encode($response);

I'm getting the answer through an android app, however with the following error:

Error parsing data org.json.JSONException: Value <html> of type java.lang.String can not be converted to JSONObject

I suspect the server is sending something else along with JSON. What do you do to prevent this?

The error received

Generally, the error Error parsing data org.json.JSONException ... refers to the inability to process JSON.

For your particular case, you can read in the error message:

Error parsing data org.json.JSONException: Value of type java.lang.String can not be converted to JSONObject

What translated:

Error processing data org.json.JSONException: Value of type java.lang.String can not be converted to JSONObject

That tells us that a string is being sent instead of an object, as expected.

Dealing with error

One way to deal with error in scenarios like this is to wrap your code in a try...catch so you can try to work the data you receive while being able to catch any errors in a way that deal with them:

try {
    JSONObject jobj = new JSONObject(response);
    String succes = jobj.getString("success");
    ...
} catch (JSONException e) {
    // ups, correu mal... vamos ver o que aconteceu
    e.printStackTrace();
}
