Android Decode JSON Encoded by PHP file

Question

I've created a JSON string in a php file. I've then used json_encode($jsonStr) to encode the string.

$jsonStr = 
            "{
                \"statusCode\": 0,
                \"errorMsg\": \"SUCCESS\",
                \"id\": $id,
                \"message\": ".json_encode($message).",
                \"author\": \"$author\",
                \"showAfter\": \"$date\"
            }";

I'm making a network call in java (Android) to get this string. My next step is to decode the string, however this doesn't seem to be working too well.

Here is a sample of what I'm trying to decode in my Android code:

{\n\t\t\t\t\"statusCode\": 0,\n\t\t\t\t\"errorMsg\": \"SUCCESS\",\n\t\t\t\t\"id\": 1,\n\t\t\t\t\"message\": \"This is a message.\",\n\t\t\t\t\"author\": \"Anonymous\",\n\t\t\t\t\"showAfter\": \"2013-06-18 01:19:49\"\n\t\t\t}

Yes it is riddled with encoded line breaks and such. I assumed that might be the issue so I took those out, however I still have issues, so I'm guessing there must be something bigger going on. I know this is valid JSON because I'm able to decode it and use it in a javascript based website.

How can I accomplish this on Android/Java?

Thats not valid JSON... And show us your complete PHP file. What is the content of $jsonStr to what are you assigning it? How do you transfer the json string etc. — DAG

I realize it isn't valid as is, however before encoding/decoding it is. One sec i'll post more details — Sababado

Your original JSON string (the one you show in your first snippet) looks to be valid JSON already. You must not encode it. Encoding it is what makes it invalid JSON, transforming every tab into \t, and every new line into \n.

Read the documentation of json_encode carefully.

Thank you for the answer. I am using json_encode to work with a my web app, however I guess my bigger issue is how i'm using it there. Thanks again.
