title: FloatingActionButton causes Activity to crash
body: <p>I have a <code>FloatingActionMenu</code> that has two <code>FloatingActionButton</code>s in it. I am trying to open a website when one of the buttons is clicked, but my app crashes when <code>homePage</code> runs.</p>
  
  <p>Here is my java code:</p>
  
  <pre><code>public class homePage extends AppCompatActivity {
  
  @Override
  protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_home_page);
  
      final String website = "http://www.facebook.com/slgnalinprogrammer";
      FloatingActionButton fabWebsite = findViewById(R.id.fabWebsite);
  
      fabWebsite.setOnClickListener(new View.OnClickListener() {
          @Override
          public void onClick(View view) {
              Intent i = new Intent(Intent.ACTION_VIEW);
              i.setData(Uri.parse(website));
              startActivity(i);
          }
      });
  }
  </code></pre>
  
  <p>My layout XML:</p>
  
  <pre><code>&lt;com.getbase.floatingactionbutton.FloatingActionsMenu
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"

      android:layout_alignParentBottom="true"
      app:fab_addButtonColorNormal="#008577"
      app:fab_addButtonColorPressed="#00574B"
      app:fab_addButtonPlusIconColor="#ffffff"
      app:fab_labelStyle="@style/custom_fab"&gt;
      &lt;com.getbase.floatingactionbutton.FloatingActionButton

          app:fab_title="Website"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          app:fab_colorNormal="#008577"
          app:fab_addButtonColorPressed="#00574B"
          app:fab_icon="@drawable/websiteicon"
