Retrieve image download url from Firebase Storage [duplicate]

Question

I am trying to retrieve an image from my firebase storage but I'm having problems storing the image download url. I am using final String downloadUrl = task.getResult().getMetadata().getReference().getDownloadUrl().toString(); but this is only reutrning a reference to the task I believe - com.google.android.gms.tasks.zzu@add13a0

What I want to be storing/retrieving is https://firebasestorage.googleapis.com/v0/b/chat-poll-application.appspot.com/o/Group%20Images%2FGig.jpg?alt=media&token=9a90fc94-e65f-4ace-9259-aaaa91b449c3

Can anyone see where I'm going wrong?

Here is the full code:

filePath.putFile(resultUri).addOnCompleteListener(new OnCompleteListener<UploadTask.TaskSnapshot>() { @Override public void onComplete(@NonNull Task<UploadTask.TaskSnapshot> task) { if (task.isSuccessful()) { Toast.makeText(GroupSettingsActivity.this, "Group image uploaded successfully", Toast.LENGTH_SHORT).show(); final String downloadUrl = task.getResult().getMetadata().getReference().getDownloadUrl().toString(); RootRef.child("Groups").child(currentGroupName).child("Image").setValue(downloadUrl) .addOnCompleteListener(new OnCompleteListener<Void>() { @Override public void onComplete(@NonNull Task<Void> task) { if (task.isSuccessful()) { Toast.makeText(GroupSettingsActivity.this, "Image saved successfully", Toast.LENGTH_SHORT).show(); loadingBar.dismiss(); } else { String message = task.getException().toString(); Toast.makeText(GroupSettingsActivity.this, "Error: " + message, Toast.LENGTH_SHORT).toString(); loadingBar.dismiss(); } } }); } else { String message = task.getException().toString(); Toast.makeText(GroupSettingsActivity.this, "Error " + message, Toast.LENGTH_SHORT).show(); loadingBar.dismiss(); } } });

Here is my database:

This does not work: getMetadata().getReference().getDownloadUrl().toString();. The call to getDownloadUrl returns a Task and you're converting that Task to a string. To get the actual download URL you need to add a completion listener to the task as shown here: stackoverflow.com/questions/51056397/… — Frank van Puffelen

Declare this object globally

Uri uri;

Set uri when user fetches the Image from the gallery

@Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); if (requestCode == 1 && resultCode == RESULT_OK && data != null && data.getData() != null) { uri = data.getData(); try { Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), uri); jimg.setImageBitmap(bitmap); } catch (IOException e) { e.printStackTrace(); } } }

Here sUrl will have downloadURL

private void uploadImage() { try { final StorageReference ref = storageReference.child( UUID.randomUUID().toString() ); //uploads the image ref.putFile( uri ).addOnSuccessListener( new OnSuccessListener<UploadTask.TaskSnapshot>() { @Override public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) { ref.getDownloadUrl().addOnSuccessListener( new OnSuccessListener<Uri>() { @Override public void onSuccess(Uri uri) { final Uri downloadUrl = uri; sUrl = downloadUrl.toString(); } } ).addOnFailureListener( new OnFailureListener() { @Override public void onFailure(@NonNull Exception exception) { } } ); } } ); }catch (Exception e){} }
