Button link to internet makes app crash

Question

I managed to make a navigation drawer and trying to get a button working now.

Code:

public class FourthFragment extends Fragment {

    @Override
    public View onCreateView(LayoutInflater inflater,
                             ViewGroup container,
                             Bundle savedInstanceState) {
        return inflater.inflate(R.layout.fourth_layout, container, false);
    }
    public void buttona1(View view){
        Intent browserIntent = new Intent(Intent.ACTION_VIEW,
                                          Uri.parse("https://www.google.nl"));
        startActivity(browserIntent);
    }
}

Layout:

<Button
    android:text="Magister"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:onClick="buttona1"
    android:id="@+id/button2"
    android:visibility="visible"
    android:layout_alignParentLeft="true"
    android:layout_alignParentStart="true"
    android:layout_alignParentTop="true"
    android:layout_alignParentRight="true"
    android:layout_alignParentEnd="true" />

The problem is that when I open the app in my mobile and move to the button page, push the button the app will close and stop working.

Just added the internet permissions to the manifest, didn't solve the problem. — Jannes van den Bogert, Jan 11 '17 at 14:00
What do you mean with initialized? When I open the app the button is there, when I click it the app fails. Where can I put the log? It is a lot and won't fit in this textbox. — Jannes van den Bogert, Jan 11 '17 at 14:37

You should initialize Context in your fragment contsructor which will be passed from your MainActivity while initializing freagment and call context.startActivity(YOUR_INTENT); hope this will help you

your code seems correct but you need to make method buttona1 in your activity and fragment both . You can't call the method from xml resides in Fragment but not in Activity

you may use the following code inside the onCreateView method

    View v=inflater.inflate(R.layout.fourth_layout, container, false);
    Button myButton=(Button)v.findViewById(R.id.button2);
    myButton.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
    buttona1(view)
    });
return v;

also replace this line

 startActivity(browserIntent);

with

getActivity().startActivity(browserIntent);
