upload image from imageview to firebase Android

Question

i have an activity with some images in a recycler view. I want to upload them into firebase storage as profile pictures but i don't know how. I have an activity with 2 image view: the first upload images from phone gallery the second one open this activity below. My idea is: click one image, it uploads the image clicked to firebase and when is finished return to last activity because user need to choose a nickname too.

package it.evilsecret.evilsecretappfinal;

import android.content.Intent;
import android.graphics.Bitmap;
import android.graphics.drawable.BitmapDrawable;
import android.net.Uri;
import android.provider.MediaStore;
import android.support.annotation.NonNull;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.GridLayoutManager;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;
import android.view.View;
import android.widget.ImageView;
import android.widget.ProgressBar;
import android.widget.Toast;

import com.google.android.gms.tasks.OnFailureListener;
import com.google.android.gms.tasks.OnSuccessListener;
import com.google.firebase.storage.FirebaseStorage;
import com.google.firebase.storage.StorageReference;
import com.google.firebase.storage.UploadTask;

import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
import java.util.UUID;

public class ImageSelection extends AppCompatActivity {

private static final int CHOOSE_IMAGE = 101;
ImageView imageView;
RecyclerView recyclerView;
ImageAdapter imageAdapter;
List<Image> imageList;
ProgressBar progressBar;

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

    imageList = new ArrayList<>();
    recyclerView = findViewById(R.id.recycler_view);
    recyclerView.setLayoutManager(new GridLayoutManager(this, 3));

    imageList.add(
            new Image(R.drawable.alis, "Alis"));
    imageList.add(
            new Image(R.drawable.astaroth, "Astaroth"));
    imageList.add(
            new Image(R.drawable.chris, "Chris"));
    imageList.add(
            new Image(R.drawable.sarah, "Sarah"));
    imageList.add(
            new Image(R.drawable.vanessa, "Vanessa"));

    imageAdapter = new ImageAdapter(this, imageList);
    recyclerView.setAdapter(imageAdapter);

To do this you have to convert the image to bitmap (convert image to bitmap)and then compress it. After that you have to upload it to firebase cloud link to firebase cloud

Convert to Bitmap first...

Bitmap bitImage = BitmapFactory.decodeResource(getResources(), imageList.get(0));

Then compress it to reduce its size...

bitImage.compress(Bitmap.CompressFormat.PNG, 100, outputStream);
