I'm using Android asyntask with Pycharm(python with flask) server and it will return an array. When i tried to connect with server it will show connection refused.
i need the solution why it shows the error like connection refused.
Android code:
public static String ip = "http://192.168.43.221:3000/";
private class BackTask extends AsyncTask<String, String, String> {
private String result = null,name,batch,id,dept,dob,phno,add,credits;
#Override
protected String doInBackground(String... params) {
try {
String data = URLEncoder.encode("device", "UTF-8") + "=" +
URLEncoder.encode(device, "UTF-8") + "&" +
URLEncoder.encode("ID", "UTF-8") + "=" +
URLEncoder.encode(regno1, "UTF-8") + "&" +
URLEncoder.encode("Password", "UTF-8") + "=" +
URLEncoder.encode(password1, "UTF-8");
BufferedReader reader = null;
Log.d("checking", data);
try {
URL url = new URL(ip + "login/");
URLConnection con = url.openConnection();
con.setDoOutput(true);
OutputStreamWriter writer = new OutputStreamWriter(con.getOutputStream());
writer.write(data);
writer.flush();
//getting response back
reader = new BufferedReader(new InputStreamReader(con.getInputStream()));
Toast.makeText(getBaseContext(),reader.readLine(),Toast.LENGTH_LONG).show();
StringBuilder s = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
s.append(line + "\n");
}
result = s.toString();
} catch (Exception e) {
// Toast.makeText(getBaseContext(),"Connection error",Toast.LENGTH_LONG).show();
e.printStackTrace();
}
} catch (UnsupportedEncodingException e) {
Toast.makeText(getBaseContext(),"Connection error",Toast.LENGTH_LONG).show();
e.printStackTrace();
}
return result;
}
#Override
protected void onPostExecute(String result) {
Toast.makeText(getBaseContext(), result, Toast.LENGTH_LONG).show();
SharedPreferences.Editor e = sp1.edit();
if(!sp1.equals(null))
{
e.putString("uname", regno1);
e.putString("pass", password1);
e.apply();
}
// progress.dismiss();
//notification.setText(result);
if (result != null) {
Toast.makeText(getBaseContext(), result, Toast.LENGTH_SHORT).show();
result = result.trim();
name= setDetails(result);
if (name.equals("success")) {
Intent intent1 = new Intent(LoginActivity.this, HrActivity.class);
//intent.putExtra("json",result);
startActivity(intent);
} else {
errormsg.setText("*Check id / password");
}
}
}
#Override

ECONNREFUSED is to mean a connection is attempted to a remote server,However the remote host is not answering back. This is much like knocking into someone's door and no one is replying back. There is no direct answer for your scnerio as many things can cause this along the way. Please have a look in this and this threads. They might give you some insight into the core issue, and from that you can start analyzing and debugging your code.

I am using the following code to write an onPostExecute process to file from my FileWriter.class, it was working fine but am updating my application and I have to use the Environment.getExternalStorageDirectory().getPath(); instead of this, i tried following. I know doing something slightly wrong. Any Help or direction would be helpful.
Thanks.
public class FileWriter {
public void appendData( String text) {
try {
File myFile = new File("/sdcard/latencyOP.csv");
// myFile.createNewFile();
FileOutputStream fOut = new FileOutputStream(myFile);
OutputStreamWriter myOutWriter =
new OutputStreamWriter(fOut);
if (myFile.createNewFile()) {
myOutWriter.append("TimeStamp,ExecutionTime,OperationType;");
}
myOutWriter.append(text);
myOutWriter.close();
fOut.close();
/**
* Toast.makeText(getBaseContext(),
* "Done writing SD 'mysdfile.txt'",
Toast.LENGTH_SHORT).show();
*/
} catch (Exception e) {
/**
* Toast.makeText(getBaseContext(), e.getMessage(),
* Toast.LENGTH_SHORT).show();
*/
}
}
}
EDIT
I forgot to add that I am attempting to do some background operations and publish results on the **FILE.csv** thread without having to manipulate threads.
UPDATED CODE #Leonardo Acevedo
try {
File myFile = new File(
Environment.getExternalStorageDirectory(),
"latencyOP.csv"
);
boolean needToCreateFile = !myFile.exists();
if (needToCreateFile) {
myFile.createNewFile();
}
FileOutputStream fOut = new FileOutputStream(myFile);
OutputStreamWriter myOutWriter =
new OutputStreamWriter(fOut);
// At this point your file is guaranteed to exist
if (needToCreateFile) {
myOutWriter.append("TimeStamp,ExecutionTime,OperationType;");
}
myOutWriter.append(text);
myOutWriter.close();
fOut.close();
Toast.makeText(getBaseContext(),
"Done writing SD 'mysdfile.txt'",
Toast.LENGTH_SHORT
).show();
} catch (Exception e) {
e.printStackTrace();
displayExceptionMessage(e.getMessage());
//Toast.makeText(this, e.getMessage(), Toast.LENGTH_SHORT).show();
}
}
public void displayExceptionMessage(String msg) {
//Toast.makeText(this, "Some Error Occured", Toast.LENGTH_SHORT).show();
}
ASYNCH TASK PROCESS
protected void onPreExecute(){ startTime = Calendar.getInstance().getTime().getTime();
}
protected void onPostExecute(Long result) {
endTime = Calendar.getInstance().getTime().getTime();
long timeDiff = endTime - startTime;
FileWriter fileWriter = new FileWriter();
String data = endTime + "," + timeDiff + "," + "Authentication" + ";";
fileWriter.appendData(data);
}
Is this wrong ?

can you please check whether below 2 API endpoints are working
You can check it using postman
Run app on server (put server ip from below urls)
String reg_url = "http://10.14.83.2:8080/register.php";
String login_url = "http://192.168.2.4:8080/login.php";
Make sure if these are working.that should return 200 response.
You can then check into database if registration data is getting saved.
hey guys i keep getting this error in my app when i try to get data from a server and read it as json and i am stuck because it doesnt happen all the time hear is the code
private class statusUpdateTask extends AsyncTask<String, String, String> {
#Override
protected String doInBackground(String... urls) {
if(testServe("http://www.gogodis.comxa.com/getData.php")) {
HttpURLConnection conn = null;
BufferedReader reader = null;
try {
URL url = new URL(urls[0]);
conn = (HttpURLConnection) url.openConnection();
conn.setReadTimeout(10000 /* milliseconds */);
conn.setConnectTimeout(15000 /* milliseconds */);
conn.setRequestMethod("GET");
conn.setDoInput(true);
conn.connect();
InputStream is = conn.getInputStream();
reader = new BufferedReader(new InputStreamReader(is));
StringBuffer sb = new StringBuffer();
String line = "";
while ((line = reader.readLine()) != null) {
sb.append(line);
}
return sb.toString();
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}else{
retry(0);
}
return null;
}
#Override
protected void onPostExecute(String result) {
if(isJSONValid(result)) {
try {
JSONObject results = new JSONObject(result);
JSONArray jr = results.getJSONArray("results");
JSONObject set = jr.getJSONObject(0);
JSONObject info = set.getJSONArray("info").getJSONObject(0);
if (info.getString("state").equals("ok")) {
if (info.getInt("inbox") == 1) {
inbox.setImageResource(R.drawable.camr);
} else inbox.setImageResource(R.drawable.cam);
if (info.getInt("chat") == 1) {
chat.setImageResource(R.drawable.msgr);
} else chat.setImageResource(R.drawable.msg);
if(info.getInt("match") == 1){
new newMatchUpdateTask().execute("http://www.gogodis.comxa.com/getData.php?type=new_match&&user=" + my_user_id);
}
}
} catch (JSONException e) {
e.printStackTrace();
}
}else{

iv'e even tried to put in code that confirms its json but still no luck
public boolean isJSONValid(String test) {
try{
new JSONObject(test);
}catch(JSONException ex){
try{
new JSONArray(test);
}catch(JSONException ex1){
return false;
}
}
return true;
}
private boolean testServe(String url) {
try{
URL myUrl = new URL(url);
URLConnection connection = myUrl.openConnection();
connection.setConnectTimeout(15000);
connection.connect();
return true;
} catch (Exception e) {
// Handle your exceptions
return false;
}
}
Try to change like this
conn.setReadTimeout(0 /* milliseconds */);//Infinite timeout
conn.setConnectTimeout(25000 /* milliseconds */);
No errors occur within when emulator is run on my android phone. Not sure if that the correct http:192.168....... When I run the app i enter the data and it says connecting to server but then says unfortunately the app crashed. Any Ideas.

NetworkOnMainThreadException [duplicate]

Closed 7 years ago.
I'm getting NetworkOnMainThreadException while using Runnable
Code:
public class FullscreenActivity extends AppCompatActivity {
public Socket socket;
public int SERVERPORT = 5000; /* port 5000 (for testing) */
public String SERVER_IP = "10.0.2.2"; /* local Android address of localhost */
ViewFlipper flipper;
ListView listing;
public void attemptConnect(View view) {
try {
EditText editTextAddress = (EditText) findViewById(R.id.address);
EditText editTextPort = (EditText) findViewById(R.id.port);
String SERVER_IP_loc = editTextAddress.getText().toString();
int SERVERPORT_loc = Integer.parseInt(editTextPort.getText().toString());
System.out.println("Attempt Connect: IP " + SERVER_IP_loc + " Port: " + SERVERPORT_loc);
System.out.println("SET");
ClientThread myClientTask = new ClientThread(SERVER_IP_loc, SERVERPORT_loc);
myClientTask.run();
System.out.println("CONNECTED");
flipper.setDisplayedChild(1);
} catch (Exception e) {
System.err.println(e.getMessage());
}
}
// Thinks the following is not a thread ??
class ClientThread implements Runnable {
ClientThread(String addr, int port) {
SERVER_IP = addr;
SERVERPORT = port;
}
public void run() {
try {
InetAddress serverAddr = InetAddress.getByName(SERVER_IP);
// gets to this line fine
socket = new Socket(serverAddr, SERVERPORT);
} catch (Exception e1) {
e1.printStackTrace();
}
}
}
}
My permissions are set up to allow internet access:
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
I'm getting the following error:

As far as I can tell, this should function as expected. It seems to think the Runnable isn't a thread, but I can't figure out why.
You need a Thread to run your Runnable for you. Simply calling run on a Runnable does not run it on a different thread.
new Thread(new ClientThread(SERVER_IP_loc, SERVERPORT_loc)).start();
