MainActivity error: cannot find symbol FloatingActionButton

Error Message: 

C:\Users\c2c\Tutiorial\app\src\main\java\com\code2care\tutiorial\MainActivity.java:25: error: cannot find symbol
        FloatingActionButton fab = findViewById(R.id.fab);
                                                    ^
  symbol:   variable fab
  location: class id

You would get the above error when you run your Android App on Android Studio, this is due to a compilation error that you have in your MainActivity.java file at like 25. You may have deleted the fab icon from the XML file but not in the code.

Remove the below lines of code from your MainActivity.java file

FloatingActionButton fab = findViewById(R.id.fab);
        fab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
            Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
             .setAction("Action", null).show();
      }
});

Run your App now it should work :) ... Happy Coding!!
