just an advice : A fragment should not start an activity, the parent activity should make the call — An-droid, Dec 31 '14 at 14:26

You were using the Button inside onCreateView, but you can't use the View before it is attached. Add the code show below & don't forget to remove the Button you created inside onCreateView

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);
    btn = (Button) rootView.findViewById(R.id.button1);
    btn.setOnClickListener(this); 
}

P.S : Let me if it works or not

The activity you're trying to start isn't declared in your manifest. Add this to your manifest:

<activity android:name=".trail" />
