I can't reproduce the error without more details.

mButton.setText("banana");

It's not sufficient, Please provide the entire code.

on the xml:

<mehdi.sakout.fancybuttons.FancyButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/startButton"
    android:layout_centerHorizontal="true"
    fancy:text="LET'S START"
    fancy:borderColor="#FFFFFF"
    fancy:borderWidth="1dp"
    fancy:textColor="#FFFFFF" />

and in the activity:

    mButton = (FancyButton) findViewById(R.id.startButton);
    mButton.setText("banana");
    mButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

        }
    });

Your code worked perfectly for me. Here is what i did

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

        Intent i = new Intent(this, yoService.class);
        startService(i);

        FancyButton mButton = (FancyButton) findViewById(R.id.startButton);
        mButton.setText("test");
        mButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Log.v("YO", "it Works");
            }
        });
    }

XML

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:fancy="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity">

    <mehdi.sakout.fancybuttons.FancyButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/startButton"
        android:layout_centerHorizontal="true"
        fancy:text="LET'S START"
        fancy:borderColor="#FFFFFF"
        fancy:borderWidth="1dp"
        fancy:textColor="#FFFFFF" />

</RelativeLayout>
