У меня есть класс AsyncTask в Kotlin, и он не запускается при вызове. Предполагается, что AsyncTask загружает данные JSON с определенного URL-адреса. Метод doInBackground никогда не запускается и ничего не происходит.
OnCreate ()
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
// TODO Remove After
// loadData()
getDataFromUrl()
// Set adapter
adapter = CardAdapter(listOfCard, this)
lvCards.adapter = adapter
}
Мой getDataFromUrl (), где вызывается AsyncTask:
private fun getDataFromUrl() {
val url = "https://pay-app-api.herokuapp.com/card/user/1"
mAsyncTask().execute(url)
}
AsyncTask Внутренний класс:
inner class mAsyncTask: AsyncTask<String, String, String>() {
override fun onPreExecute() {
Log.d(TAG, "Pre Execute")
super.onPreExecute()
}
override fun doInBackground(vararg params: String?): String? {
try {
// Connect to URL
val url = URL(params[0])
val urlConnect = url.openConnection() as HttpURLConnection
// urlConnect.connectTimeout = 5000
// Read Data from URL
val mInputString =
convertStreamToString(urlConnect.inputStream)
publishProgress(mInputString)
} catch (ex: Exception) {}
return ""
}
override fun onProgressUpdate(vararg values: String?) {
try {
val json = JSONObject(values[0])
tvJsonTest.text = "Downloaded"
Log.d(TAG, json.toString())
System.out.print("Downloading...")
} catch (ex: Exception) {}
// super.onProgressUpdate(*values)
}
}
И журналы LogCat:
