Passing string value from activity class to a non activity class

i'm new in android and i'm trying to pass a string from a TextView from the MainActivity to the Client.java class without activity.
I'm actually trying to make it doing in MainActivity :
Intent i = new Intent(MainActivity.this, Client.class);
i.putExtra("STRING_I_NEED", String.valueOf(indr));
While in Client :
Context context;
Intent intent = ((Activity) context).getIntent();
static Bundle getIp = getIntent.getExtra("STRING_I_NEED");
public static final Bundle SERVERIP = getIp;
But that's saying "
Cannot resolve symbol "getIntent" in the string
static Bundle getIp = getIntent.getExtra("STRING_I_NEED");
Client code:
public class Client {
private static String mIP= "";
private String serverMessage;
public static final String SERVERIP = mIP;
public static final int SERVERPORT = 4444;
private OnMessageReceived mMessageListener = null;
private boolean mRun = false;
PrintWriter out;
BufferedReader in;
public void setIp(String _IP) {
mIP = _IP;
}
public Client(OnMessageReceived listener) {
mMessageListener = listener;
}
public void sendMessage(String message){
if (out != null && !out.checkError()) {
out.println(message);
out.flush();
}
}
public void stopClient(){
mRun = false;
}
public void run() {
mRun = true;
try {
InetAddress serverAddr = InetAddress.getByName(String.valueOf(SERVERIP));
Log.e("TCP Client", "C: Connecting...");
Socket socket = new Socket(serverAddr, SERVERPORT);
try {
out = new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket.getOutputStream())), true);
Log.e("TCP Client", "C: Sent.");
Log.e("TCP Client", "C: Done.");
in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
while (mRun) {
serverMessage = in.readLine();
if (serverMessage != null && mMessageListener != null) {
mMessageListener.messageReceived(serverMessage);
}
serverMessage = null;
}
Log.e("RESPONSE FROM SERVER", "S: Received Message: '" + serverMessage + "'");
} catch (Exception e) {
Log.e("TCP", "S: Error", e);
} finally {
socket.close();
}
} catch (Exception e) {
Log.e("TCP", "C: Error", e);
}
}
public interface OnMessageReceived {
void messageReceived(String message);
}
}
And here is the MainActivity :
public class MainActivity extends AppCompatActivity {
Server server;
Client client;
public static String message,ippi;
public static TextView terminale,indr,msg;
TextView log;
DataBaseHandler myDB;
allert Allert;

Problem:
Since Client.java (according to you) is not an Activity type class, you cannot call/invoke Client.java using an Intent. Intent is only used for invoking: Activities, BroadcastReceiver, and Services.
Your Client.java does not extend an Activity, Broadcast, or a Service. This is the reason why you don't have the getIntent() function, or even the functions onCreate(), onReceive(),onStartCommand()oronHandleIntent()'` for that matter.
Correct way:
1. So what you have to do is create an object of that class just like any other object and call its setter. You can define a public method in you class to set the value of IP:
YourClass {
private String mIP;
public void setIp(String _IP) {
mIp = _IP;
}
}
And in the MainActivity class you can just call that method after the object is initialized:
MyClassObject.setIp("127.0.0.1");
2. Define an overloaded constructor, and set the value using it.
3. Create a public static String IP in MainActivity, assign value to it and then in your class do this to retrieve the value:
YourClass {
private String mIP;
public void getIp() {
mIP = MainActivity.IP;
}
}

In your Client class.
public void setString(String yourString){
variableToStoreStringInClass = yourString;
}
And in your MainActivity, where you want to send the string to the Client.
Client yourClient = new Client();
yourClient.setString("Enter the string");
Or you can use an static method:
In Client class:
public static void setString(String yourString){
variableToStoreStringInClass = yourString;
}
And in your MainActivity
Client.setString("Enter the string");

In your Settings activity when you set the String in that TextView also save it in a shared preference like this:
SharedPreferences prefs = this.getSharedPreferences(
"com.example.app", Context.MODE_PRIVATE);
prefs.edit().putString("IP", IP_String).apply();
And then in main activity:
SharedPreferences prefs = this.getSharedPreferences(
"com.example.app", Context.MODE_PRIVATE);
String ip = prefs.getString("IP", "AnyDefaultValue");
client.setIp(ip);

Intialize static string in MainActivity and assign textView text to that string.
In Client.java call like this MainActivity.IntializedString

Try following sample
public class Client {
Context context;
Intent intent;
String value = "";
public Client(Activity activity) {
context = activity;
intent = ((Activity) context).getIntent();
value = intent.getStringExtra("String_i_need");
}
}

Can't use the SASLXFacebookPlatformMechanism class in making android xmpp facebook chat client

I m trying to make a simple version facebook messenger.The code that i used has worked well for gtalk and requires facebook authentication to be used for chatting with facebook friends.For that, i have used SASLXFacebookPlatfromMechanism class where i will store the api token and api key along with the apisecret of my app. The problem is SASLXFacebookPlatfromMechanism.java class is full of errors which i cannot resolve at all.Here are my classes-

I am also confused on how to use this SASLXFacebookPlatformMechanism.java class in my MainActivity.class.I have been trying to get a sense of how it works but failing.A complete guideline on how to develop a xmpp facebook chat client using asmack library would be appreciated since the internet lacks enough documentation on it.Thanks.
[I have the apikeys and apitokens,so the empty string will not remain empty]

when i debug my code this will get the connection values but terminate on this line MainActivity.setConnection(connection);
now what i am doing wrong

getText(int host)
is returning null for host, port, service, username and password. That will not bring you very far.
