I am new to the Kotlin langue and have tried to learn from various YouTube tutorials and other articles online. I took what I learned from a video and followed the steps to create a straightforward currency converter using a free API currency rate. The following is the function for getting the result of the currency rate.
private fun getApiResult(){ var baseCurrency = "EUR" var convertedToCurrency = "USD" var conversionRate = 0f if(et_firstConversion != null && et_firstConversion.text.isNotEmpty() && et_firstConversion.text.isNotBlank()){ val API = "http://data.fixer.io/api/latest?access_key=a22e608d4311d9ade9221a2abadb111e&symbols=$convertedToCurrency,AUD,CAD,PLN,MXN&format=1" if(baseCurrency == convertedToCurrency){ Toast.makeText(applicationContext,"Cannot convert the same currency", Toast.LENGTH_SHORT).show() } else { GlobalScope.launch(Dispatchers.IO){ try { val apiResult = URL(API).readText() val jsonObject = JSONObject(apiResult) conversionRate = jsonObject.getJSONObject("rates").getString(convertedToCurrency).toFloat() Log.d("Main", "$conversionRate") Log.d("Main", apiResult) withContext(Dispatchers.Main){ val text = ((et_firstConversion.text.toString().toFloat()) * conversionRate).toString() et_secondConversion?.setText(text) } } catch (e:Exception){ Log.e("Main", "$e") } } } } } The problem is that the Exception gets triggered and says the following: cleartext http traffic is not permitted
In the Manifest.xml, I have set the following:
<uses-permission android:name="android.permission.INTERNET"/> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/> The free API is very restricted toward free users and does not allow for Https. I am also not sure if the coding(the way it is implemented) is doing what I am trying to achieve in the right way. Any suggestions/improvements to the code are appreciated.
