passing data from activity to activity in android

What is the problem with my code :(

This is the sending class:

public class Send extends AppCompatActivity {

String message_text;
final static String MSG_KEY = "this.is.the.message";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.send_layout);
}

public void sendMessage(View view) {
    EditText entryText = (EditText)findViewById(R.id.message_text);
    message_text = entryText.getText().toString();
    Intent intent = new Intent(this, MainActivity.class);
    intent.putExtra(message_text, MSG_KEY);
    startActivity(intent);
}

}

this is the receiver:

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    TextView theMessage = (TextView)findViewById(R.id.theMessage);
    theMessage.setText(getIntent().getStringExtra("this.is.the.message"));
}

}

the app starts but it does not pass text, just an empty recieving activity ???

If changing intent.putExtra(MSG_KEY, message_text); doesn't fix the issue. Check AndroidManifest.xml to make sure that MainActivity is not the launcher otherwise your MainActivity starts before the send class.

You are using value as key and key as value which is causing this issue.

Change 

intent.putExtra(message_text, MSG_KEY);

to

intent.putExtra(MSG_KEY, message_text);

intent.putExtra(message_text, MSG_KEY);

replace with

intent.putExtra(MSG_KEY, message_text);

Frist argument is NAME , second argument - VALUE
