How to parse escaped Json using JSONObject in android

Question

I'm unable to parse escaped json string through JSONObject, while trying to parse it, I always get an Unterminated Object error. But when I manually remove all of the escape characters from the json string, JSONObject parses it successfully.

But the problem is that for complex or nested json strings, I don't want to remove escape characters, because for nested structures, unescaping the characters results in an invalid json string.

This is the json string after removing escapes characters and I get unterminated object error due to invalid json when parsing through JSONObject

{"result":"unknown","message":"{"firebase":"unknown"}","sender":"unknown"}

This is the unescaped json string

{"result":"unknown","message":"{\"firebase\":\"unknown\"}","sender":"unknown"}

Answer 1

If you look at the json you are constructing it in wrong format.

In case of escaped json

{
    "result":"unknown",
    "message":"{"firebase":"unknown"}",
    "sender":"unknown"
}

the json object "message" is having value "{" and firebase is causing exception.

In the the escaped json "message":{"firebase":"unknown"} will form valid json.
