}
The problem is i am able to sending the data to the ubidots however i want to make it so that only if the condition has met, it will then send to the cloud. Other than that, it would not have send any data to the cloud.

how can i get toast message?

You need to do that on onPostExecute since it is running on the UI thread. And also in Java string comparison is like s.equals("Failed"):
#Override
protected void onPostExecute(String s) {
super.onPostExecute(s);
if (!s.equals("FAILED")) {
Log.d(TAG, s);
Toast.makeText(context, "토스트메시지입니다.", Toast.LENGTH_SHORT).show();
}
}

Use Toast.makeText(context, "토스트메시지입니다.",Toast.LENGTH_SHORT).show();`
#Override
protected void onPostExecute(String s) {
super.onPostExecute(s);
if (s != "FAILED") {
Log.d(TAG, s);
Toast.makeText(context, "토스트메시지입니다.", Toast.LENGTH_SHORT).show();
}
}

Error:(103, 68) error: local variable context is accessed from within inner class; needs to be declared final. You just need using "context" instead of "getApplicationContext()".

There are two user chats in my database, namely Messaging, Chat and I'm getting the both from database into ArrayList but it is only showing Messaging.
Adapter display:
Response from database:

Check recycler_view in your main layout. The height should be set to "wrap_content".

Can't create handler inside thread that has not called Looper.prepare()

EDIT: My solution was to have a constant class with this code:
static EditText Port = (EditText) MainActivity.mDialog.findViewById(R.id.txtPort); static int mPort = Integer.parseInt(Port.getText().toString()); public static final int PORT = mPort;
I've tried to see the other questions and I understand that I've gotta do something with the UIThread? Honestly, I understand nothing. Im new with android.
The app (chat app) worked fine until I wanted to have multiple ports options depending if I'm hosting (port 5050) or joining (port 80) a chat room. From the beginning i just had a constant value of the port (public static final int PORT) but now i cant have that ofc. If you guys have any other suggestions on how i can have two values of PORT, please share your tips.
Anyway, after trying EVERYTHING I decided to put a method in my main class, and just declare it in other classes. This is the mothod for the value of the port:
public int getPORT() {
txtPORT = (EditText) findViewById(R.id.txtPort);
//String txtPORTa = txtPORT.getText().toString();
int dennaPORT = 0;
if (mJoin.isChecked()) {
dennaPORT = Integer.parseInt(txtPORT.getText().toString());
return dennaPORT;
}
else if (mHost.isChecked()) {
dennaPORT = 5050;
return dennaPORT;
}
return dennaPORT;
}

NEVER create an instance of an Activity, Service, or ContentProvider yourself. Those are always created by the framework. Delete:
MainActivity porten = new MainActivity();
Pass the port into the strangely-named Server class by some other means, such as a constructor parameter or setter method.
