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.

Solution:

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!!
