私の問題はこれとほとんど同じですが、まだ出力ストリームを作成していません
// Try to connect
try {
// Check the network state
ConnectivityManager connMgr = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo networkInfo = connMgr.getActiveNetworkInfo();
// If there is conection, try to create a socket with remote server
if (networkInfo.isConnected()) {
InetAddress address = InetAddress
.getByName(serverAdressTextField.getText().toString());
Socket serverConnection = new Socket(address, PORT);
// Write message of success
//TODO Implement the rest of login function
Toast.makeText(this, "Connected", Toast.LENGTH_SHORT).show();
} else {
// Say user that there is no internet
Toast.makeText(this, "No connection", Toast.LENGTH_SHORT)
.show();
}
// Catch unknown host and prompt error
} catch (UnknownHostException e) {
Toast.makeText(this, "Server is not reached", Toast.LENGTH_SHORT)
.show();
return;
// Prompt IO exception
} catch (IOException e) {
Toast.makeText(this, "I/O Error", Toast.LENGTH_SHORT).show();
return;
// Any other exception, not good
} catch (Exception e) {
Toast.makeText(this, "Unknown Error", Toast.LENGTH_SHORT).show();
return;
}
それは IllegalStateException をスローし、キャッチされない場合はそれを与えます
