Null image on firebase storage. How to save it original?

I have tried to solve an issue on my app but I couldn't find a solution. I want the app to upload the images on Firebase Storage after the post is clicked. The problem is that when I click post the images are uploaded as .null and I can't add them as posts on my app here is a photo of Firebase Storage:
Here is the code of PostsActivity:

private String getFileExtension(Uri uri) {

MimeTypeMap mimeTypeMap = MimeTypeMap.getSingleton();
return mimeTypeMap.getExtensionFromMimeType(contentResolver.getType(uri));
}
private void uploadImage() {

progressDialog.setMessage("Posting please wait..");
progressDialog.show();
if (imageUri != null) {

return fileReference.getDownloadUrl();
}
}).addOnCompleteListener(new OnCompleteListener<Uri>() {
#Override
public void onComplete(#NonNull Task<Uri> task) {
if (task.isSuccessful()) {
Uri downloadUri = task.getResult();
myUrl = downloadUri.toString();
DatabaseReference reference = FirebaseDatabase.getInstance().getReference("posts");
String postId = reference.push().getKey();
HashMap<String, Object> hashMap = new HashMap<>();
hashMap.put("postId", postId);
hashMap.put("postImage", myUrl);
hashMap.put("description", description.getText().toString());
hashMap.put("publisher", FirebaseAuth.getInstance().getCurrentUser().getUid());
reference.child(postId).setValue(hashMap);
progressDialog.dismiss();
startActivity(new Intent(PostActivity.this, MainActivity.class));
finish();
}else {
Toast.makeText(PostActivity.this, "Failed.", Toast.LENGTH_SHORT).show();
}
}
}).addOnFailureListener(new OnFailureListener() {
#Override

}
});
}else {
Toast.makeText(this, "No image selected.", Toast.LENGTH_SHORT).show();
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == CropImage.CROP_IMAGE_ACTIVITY_REQUEST_CODE && resultCode == RESULT_OK) {
CropImage.ActivityResult result = CropImage.getActivityResult(data);
imageUri = result.getUri();
image_added.setImageURI(imageUri);
}else {
Toast.makeText(this, "Something gone wrong", Toast.LENGTH_SHORT).show();
startActivity(new Intent(PostActivity.this, MainActivity.class));
}
}
}
I thought that I have to initialize Uri inside onCreate method but nothing changed. What should it be?

I found the solution for anyone else who has the same issue, the solution is that I should have added a ! into this if, like this:
if (!task.isSuccessful()) {
throw task.getException();
}

It has been noticed that the method you are using to retrieve the file mime type doesn't work on some devices. You could try some other alternatives like using apache commonsIO lib or alternatively try this code :
public String getMimeType(Uri uri) {
String mimeType = null;
if (ContentResolver.SCHEME_CONTENT.equals(uri.getScheme())) {
ContentResolver cr = getAppContext().getContentResolver();
mimeType = cr.getType(uri);
} else {
String fileExtension = MimeTypeMap.getFileExtensionFromUrl(uri
.toString());
mimeType = MimeTypeMap.getSingleton().getMimeTypeFromExtension(
fileExtension.toLowerCase());
}
return mimeType;
}

How to store user's provider account in Firebase Realtime Database?

I would like you to help me, please. Thanks before

To solve this, please change the following line of code:
DatabaseReference providerLoginRef;
to
DatabaseReference providerLoginRef = FirebaseDatabase.getInstance().getReference();
So you got that error because your providerLoginRef object was never initialized.

User has google account or email account logout force closed firebase

I've logined google account on the application but when I logout of the system, the application force closed. In another, couldn't show google account chooser when I started to login the application again
This was the code I've tried and the problem is null object reference on methode GoogleSignIn Client and I couldn't find method revokeaccess cause it was unavailable.

I expected when I login with either email or google account and then Logout without conflict. So, How should I do?

Following the document here google-signin
Just only FirebaseAuth.getInstance().signOut(); to logout
So you might have to call signOutApp() function only.

I can select an image from the device but it wont upload on and due to that, I am unable to create a user

For my app to register a user all it fills needs to be filled. However when I select an image when clicking on the image view; it doesn't come up, and after filling the other detail I can't create a new user due to the the imageview not being filled. I don't have no errors in my logcat.It only stopped creating a new user after implementing the Image part in the code.

Check the condition you wrote in onActivityResult :)
The second requestCode should be resultCode.
Change:
(requestCode == PICK_IMAGE && requestCode == RESULT_OK &&
data.getData() != null)
To:
(requestCode == PICK_IMAGE && resultCode == RESULT_OK &&
data.getData() != null)
