title: onStart and Override Error in android studio
body: <p>I wrote some code to get data from Firebase, but it shows some errors. I will explain the errors below and attach a picture.</p>
  
  <p><img src="https://i.stack.imgur.com/unqs6.png" alt="enter image description here"></p>
  
  <p><strong>First error when I put the mouse on it, message show:</strong>
  'onStart()' in 'com.abdullrahman.eng.myapp.FriendsFragment' clashes with 'onStart()' in 'android.app.Fragment'; attempting to assign weaker access privileges ('protected'); was 'public'</p>
  
  <p><strong>Second error when I put the mouse on it, message show:</strong>
  Method does not override method from its superclass</p>
  
  <p>Can anyone solve these problems and help me?</p>
  
  <p>The code:</p>
  
  <pre><code>@Override
  protected void onStart() {
      super.onStart();
  
      FirebaseRecyclerAdapter&lt;Friends, FriendsViewHolder&gt; firebaseRecyclerAdapter = new FirebaseRecyclerAdapter&lt;Friends, FriendsViewHolder&gt;(
  
              Friends.class,
              R.layout.users_single_layout,
              FriendsViewHolder.class,
              mUsersDatabase
  
      ) {
          @Override
          protected void populateViewHolder(FriendsViewHolder friendsViewHolder, Friends friends, int position) {
  
              friendsViewHolder.setDisplayName(friends.getName());
              friendsViewHolder.setUserStatus(friends.getStatus());
              friendsViewHolder.setUserImage(friends.getThumb_image(), mMainView.getContext());
  
              final String user_id = getRef(position).getKey();
  
              friendsViewHolder.mView.setOnClickListener(new View.OnClickListener() {
                  @Override
                  public void onClick(View view) {
  
                      Intent profileIntent = new Intent(getActivity(), UserProfile.class);
                      profileIntent.putExtra("user_id", user_id);
                      startActivity(profileIntent);
  
                  }
              });
          }
      };
  
      mUsersList.setAdapter(firebaseRecyclerAdapter);
  
  }
  </code></pre>
