Fetching Image Issue from firebase using Picasso

I have done with the text feteching from the database, buit while fetching image from the database using picasso the images are not loading the phone and the logcat is displaying the error :

com.example.lenovo.skanda E/StorageUtil: error getting token java.util.concurrent.ExecutionException: com.google.firebase.internal.api.FirebaseNoSignedInUserException: Please sign in before trying to get a token.

The textviews are easily getting fetching from the firebase. But in case of ImageView its not loading properly.

QuoteList.java

public class QuoteList extends AppCompatActivity {

    private StorageReference storageRef;

    RecyclerView  mRecyclerView;
    FirebaseDatabase mFirebaseDatabase;
    DatabaseReference mReference;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_quote_list);

        //ActionBar actionBar = getSupportActionBar();
        //getSupportActionBar().setTitle("Quotes");
        //getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        //getSupportActionBar().setHomeButtonEnabled(true);

        final LinearLayoutManager layoutManager = new LinearLayoutManager(this);
        layoutManager.setOrientation(LinearLayoutManager.VERTICAL);
        mRecyclerView = findViewById(R.id.quotes_list);
        mRecyclerView.setLayoutManager(layoutManager);


        mFirebaseDatabase = FirebaseDatabase.getInstance();
        mReference = mFirebaseDatabase.getReference("Quotes");
    }





    @Override
    protected void onStart() {
        super.onStart();

        FirebaseRecyclerAdapter<Quote, QuoteViewHolder> firebaseRecyclerAdapter =
                new FirebaseRecyclerAdapter<Quote, QuoteViewHolder>(
                        Quote.class,
                        R.layout.quote_row,
                        QuoteViewHolder.class,
                        mReference
                ) {

                    @Override
                    protected void populateViewHolder(QuoteViewHolder viewHolder , Quote model , int position) {

                     //   viewHolder.setDetails(getApplicationContext(), model.getQuotes(), model.getQuote_Author(), model.getImages());
                            viewHolder.setQuotes(model.getQuotes());
                            viewHolder.setQuoteAuthor(model.getQuote_Author());
                            viewHolder.setImage(getApplicationContext(),model.getImages());


                    }
                };

        mRecyclerView.setAdapter(firebaseRecyclerAdapter);

    }

    public static class QuoteViewHolder extends RecyclerView.ViewHolder{

        View mView;

        public QuoteViewHolder(View itemView) {
            super(itemView);

            mView = itemView;
        }

        public void setQuotes(String Quote){
            TextView post_quote = (TextView) mView.findViewById(R.id.post_quote);
            post_quote.setText(Quote);
        }

        public void setQuoteAuthor(String QuoteAuthor){
            TextView post_quoteAuthor = (TextView) mView.findViewById(R.id.post_author);
            post_quoteAuthor.setText(QuoteAuthor);
        }

        public void setImage(Context ctx, String image){
            ImageView post_image = (ImageView) mView.findViewById(R.id.post_image);
            Picasso.get().load(image).into(post_image);

        }
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {

        getMenuInflater().inflate(R.menu.main_menu, menu);
        return super.onCreateOptionsMenu(menu);
    }
}

I am also attaching the logcat error report. Please go through it.

You are getting the follwing error:

java.util.concurrent.ExecutionException: com.google.firebase.internal.api.FirebaseNoSignedInUserException: Please sign in before trying to get a token.

Because by default, your are security rules require your user to be authenticated.

allow read, write: if request.auth != null;

To solve this, you can either make sure your user is authenticated before trying to diplay the image or change the security rules to:

allow read, write;

But I recommend you to use these rules only for testing purposes. Don't keep this rules always like this. Secure your Firebase realtime database, as well as Firebase Storage.
