java.lang.reflect.InvocationTargetException appears while starting Activity

This is a block of code inside my ListView Customized Adapter :

@Override
public View getView(int i, View convertView, ViewGroup parent) {
    final MovieEntity feedItem=feedTrailersList.get(i);

    //LinearLayout Trailers_Linear=(LinearLayout) convertView.findViewById(R.id.Trailers_Linear);

    View view=convertView;
    if (view==null){
        view=LayoutInflater.from(getContext()).inflate(R.layout.trailer_list_item, parent,false);
    }
    TextView trailerName=(TextView)view.findViewById(R.id.trailer_name);
    trailerName.setText(feedItem.getTRAILER_NAME_STRING());
    trailerName.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent intent=new Intent(String.valueOf(Intent.FLAG_ACTIVITY_NEW_TASK));
            intent.setData(Uri.parse(feedItem.getTRAILER_KEY_STRING()));
            mContext.startActivity(intent);

        }
    });
 return view;
}

Here, i am trying to startActivity via my Context, as i am in a cutomized adapter class not in an activity, but it gives me this error titles :

ex: java.lang.reflect.InvocationTargetException
cause : android.util.AndroidRuntimeException: Calling startActivity() from outside of an Activity  context requires the FLAG_ACTIVITY_NEW_TASK flag. Is this really what you want?

i was using Intent intent=new Intent(Intent.ACTION_VIEW); flag, and tried Intent intent=new Intent(String.valueOf(Intent.FLAG_ACTIVITY_NEW_TASK)); after it displayed this exception.

Can anybody tell my what does this exception refers to, your aid is completely, and respectively appreciated. Thanks in advance.

This is my block of current Intent Code now, and it's working

Intent intent=new Intent(); 
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);     
intent.setData(Uri.parse(feedItem.getTRAILER_KEY_STRING())); 
getContext().startActivity(intent);
