Upload Image on Firebase Storage

Hi I want to add an image on firebase storage with android studio but firebase doesn't accept my upload. I changed the rule to allow the write and read and my match folder allows all path.Thus I am confused. Here is the part of my code who should put the image in my database.
If you know how to resolve this problem i would be glad to ear a solution
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK && requestCode == PICK_IMAGE){
image_uri = data.getData();
uploadPicture();
ProfileImage.setImageURI(image_uri);
}
}
private void uploadPicture() {
final ProgressDialog pd = new ProgressDialog(this);
pd.setTitle("Uploading Image...");
pd.show();
final String randomKey = UUID.randomUUID().toString();
StorageReference riversRef = storageReference.child(("images/" + randomKey + ".jpg"));
Toast.makeText(Create_Profile.this, "Upload success", Toast.LENGTH_SHORT).show();
riversRef.putFile(image_uri)
.addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
pd.dismiss();
name = riversRef.getDownloadUrl().toString();
}
}).addOnProgressListener(new OnProgressListener<UploadTask.TaskSnapshot>() {
#Override
public void onProgress(#NonNull UploadTask.TaskSnapshot snapshot) {
double progressPercent = (100.00 * snapshot.getBytesTransferred() / snapshot.getTotalByteCount());
pd.setMessage("Percentage: " + (int) progressPercent + "%");
}
});
}

if you don't getting error compare with this simple code
thank you

I found a solution by modifying my firebase Rules to match with the bucket directly and not with the ref of my firebase storage

User does not have permission to access this object . with storage firebase

I am making an android application which is sort of a social media app
but when I am trying to put image from gallery or from camera for profile or cover this problem occurs.
I want the user to select a photo from his gallery or take a new picture using camera and then upload the image to Firebase Storage.
User does not have permission to access this object using Firebase Storage.
There are my permissions ..
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.INTERNET" />

FIrebase Security Rules:
service firebase.storage {
match /b/learno-fc8fc.appspot.com/o {

}
Screenshot of the issue.

Can you please cross check your bucket name if it correct.

After searching i found solution ..
My rules in Firebase was not right ..
we should make it like that ..
service firebase.storage
{ match /b/learno-fc8fc.appspot.com/o
{ match /{allPaths=**}
{ // Allow access by all users
allow read, write; }

startActivityForResult(intent, 101);
}
here is my xml code
<de.hdodenhof.circleimageview.CircleImageView
android:id="#+id/img_profile"
android:layout_width="150dp"
android:layout_height="150dp"
android:src="#drawable/useree1"
app:civ_border_width="2dp"
app:civ_border_color="#FF000000"
android:elevation="10dp"
android:scaleType="centerCrop"
android:layout_below="#+id/header_cover_image"
android:layout_centerHorizontal="true"
android:layout_marginTop="-80dp"/>
<de.hdodenhof.circleimageview.CircleImageView

try this way :
SharedPreferences sharedPreferences = getPreferences(MODE_PRIVATE);
String profileImage = sharedPreferences.getString("profile_image", "");
Bitmap bitmap = decodeToBase64(profileImage);
public static Bitmap decodeToBase64(String str) {
byte[] decodedByte = Base64.decode(str, 0);
return BitmapFactory.decodeByteArray(decodedByte, 0, decodedByte.length);
}

I'd recommend the Glide image handling library...
Makes this a lot easier...
https://github.com/bumptech/glide
ImageView imgView = findViewById(R.id.imageview);
Glide
.with(context)
.load(imageBytes)
.centerCrop()
.into(imgView);

How to create a tinder/bumble like "Edit Profile Images" page in android studio with firebase?

I'm trying to create an app where you can add profile images from your mobile device, then save it to firebase, and retrieve it from firebase as well, as efficiently as possible.
A few questions:
1: How do these big dating apps such as bumble/tinder create the edit profile image UI where you upload your profile images and rearrange them? Do they place cardviews into a gridview, seeing as how these cards have the ability to be dragged to rearrange the position? Also they normally have a small x button attached to delete the image, so it would be a cardview, right?
I'm currently using ImageViews for testing and wanted to incorporate the ability to add more, but my code is horrible and it overwrites the images in the firebase DB if I return to the page and add a new image.

Currently I can upload images to the imageviews fine and save them to firebase, but for example if I upload 2 images, then save and return to upload a 3rd image, that image overwrites image 1. Does anyone have a simpler way of doing this?

So after looking at the other apps at my disposal again, I've realized that it seems they upload the image to firebase after the onResultActivity of the image selection of your phone gallery. So i've simplified my code to do the same and it works much better. Code now works but I just need to resize the images to fit the imageviews properly, other than that no complaints.
If you have a better and more efficient way of writing this code, please comment, efficiency is key and I would appreciate your input.

You can use custom alertdialog.
LayoutInflater inflater = getLayoutInflater();
View dialoglayout = inflater.inflate(R.layout.dialog_layout, null);
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setView(dialoglayout);builder.show();
before you must create dialog_layout.xml

are you sure that it doesn't work? Your code is correct. It could be perfectly show on Nexus 5.
