[Android Central Question]

old code

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;

public class MainActivity extends AppCompatActivity {

public void clickFunction(View view) {

Log.i("Info", "It worked!!");

}

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

new code

package com.example.myapplication;

import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;

public class MainActivity extends AppCompatActivity {
private String tag,msg;

public void clickFunction(View view){
Log.i( tag:"Info" , msg :"Button Pressed");
}

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

First learn programming, including object oriented programming - in English. (You don't 'build an app', you solve a problem. Then you code the solution into Java/Kotlin.)
