I'm trying to download web content from my android application. But whenever I run, I have the problem below. I'm using android studio 3.5.1 on Mac.
Here are some code..
protected String doInBackground(String... urls) {
String result = "";
URL url;
HttpURLConnection httpURLConnection= null;
try {
url = new URL(urls[0]);
httpURLConnection = (HttpURLConnection) url.openConnection();
InputStream inputStream = httpURLConnection.getInputStream();
InputStreamReader reader = new InputStreamReader(inputStream);
int data = reader.read();
while (data != -1){
char current = (char) data;
result += current;
data = reader.read();
}
return result;
} catch (Exception e) {
e.printStackTrace();
return "Failed";
}
}
The following are the error code:
