Android Studio – android studio volley web request

I’m trying to make a get request to an API that returns a JSON array on android studio but when I check the logs it says that there was a problem… (I use kotlin by the way)

What did I do wrong?

here is my code:

val url = "http://example.com"
    val queue = Volley.newRequestQueue(context)

    val jsonArrayRequest = JsonArrayRequest(Request.Method.GET, url, null,
        {
            

            Log.d("notification", "successful request!")
        },
        {
            Log.d("notification", "error on request...")
        })

    queue.add(jsonArrayRequest)
}

    After reading Techno World's answer I had an idea. Basically it's the same thing Techno World did but much easier. What I did is to print the response to the log like this:

    val url = "http://example.com"
val queue = Volley.newRequestQueue(context)

val jsonArrayRequest = JsonArrayRequest(Request.Method.GET, url, null,
    {
        Log.d("notification", "successful request!")
    },
    {response ->
        Log.d("notification", "error on request: $response")
    })

queue.add(jsonArrayRequest)
}

    So when I checked the log I saw this:

    error on request: com.android.volley.noconnectionerror: java.io.ioexception: cleartext http traffic to example.com not permitted

    After some research I found out that it was because I used http instead of https. So I changed it and it worked!

    Here is the original question on stack overflow about that error, there are more methods to solve it...

    var reqParam = URLEncoder.encode("username", "UTF-8") + "=" + URLEncoder.encode(userName, "UTF-8")
    reqParam += "&" + URLEncoder.encode("password", "UTF-8") + "=" + URLEncoder.encode(password, "UTF-8")

    val mURL = URL("<Yout API Link>?"+reqParam)

    with(mURL.openConnection() as HttpURLConnection) {
        // optional default is GET
        requestMethod = "GET"

        println("URL : $url")
        println("Response Code : $responseCode")

        BufferedReader(InputStreamReader(inputStream)).use {
            val response = StringBuffer()

            var inputLine = it.readLine()
            while (inputLine != null) {
                response.append(inputLine)
                inputLine = it.readLine()
            }
            it.close()
            println("Response : $response")
        }
    }

    Try this it will help solve your problem..
