Anyone know how to solve this problem. Thanks a lot.
Also that, I also face problem when try to display the message in my apps. There was no problem with other field such as Text, RadioButton, Date, only photo I unable to up the real url.
fyi. currenly the url display in firebase database is the photo storage location
It seems like the user is not signed (authenticated from the Firebase ) .
their is two method to solve the problem
1)authenticate the user using authentication
2)set your rule to public for fire-base real-time database
copy and paste this rule in Firebase real-time database >rule
{
"rules": {
".read": true,
".write": true
}
}
But doing this will make
your security rules are defined as public, so anyone can steal, modify or delete data in your database
The Exception clearly says that you are trying to perform operations without having the user logged in.
You can follow this manuel to authenticate and then perform your operations

I'm trying to add data to a document to Firebase Firestore. I've added a collection named users to it. Also, the read/write permissions are open for now. I'm following this doc. And I'm not able to add data to document only on this Activity. on other activity, I can add data easily

Try this
#Override

if(response.isSuccessful()) {
UserRegistrationModel res = response.body();
if(res!=null) {
Toast.makeText(view.getContext(), res.getStatus(), Toast.LENGTH_LONG).show();
} else {

}
}
}
Your com.dgdev.mtmicds.DbAccess.Remote.UserRegistrationModel is null. Check whether it is being alloted any value by getting in debug mode. Run the code step by step in debug mode and check how it is getting initialized.
Hint: Check this line of your code in debugger:
UserRegistrationModel res = response.body();
Here in this class i m generating the qRcode and saving it tot the firebase storage everything is working fine but problem is everytime the qrcode is saved with same name i.e "QR Codes".I want to save the qRcode with different name for diffrent user in QRCodes Folder of Firebase Storage.

The issue comes with these two lines:
mStorage = FirebaseStorage.getInstance().getReferenceFromUrl("gs://.../QR codes/");
...
UploadTask uploadTask = mStorage.putBytes(data);
This means that you're uploading to a file named QR%20codes and overwriting it. Instead you need to add a distinct identifier to each file being uploaded:
UploadTask uploadTask = mStorage.child(some-generated-uuid).putBytes(data); // "QR%20codes/some-generated-uuid"
Read our docs on creating references, which hopefully provides some more information. If you're looking for unique names, see this SO post on the subject.

I am able to store(Simply put using object) data in Pay table as well as also get from table but when I am trying to update it doesn't show any change in table..........
same I am applying for Current User(renter data) it done all get data,update but except current user others users data not update
I do not want to try and understand such a large block of code. In the future please try and boil down the relevant pieces. However:
Looks like you do a query right after saving. Note that saveInBackground() is async, thus it starts (as the name suggests) to contact parse.com and save in a background thread. If the query depend on the object being saved, then you need to wait for it to complete by adding the SaveCallback parameter saveInBackground(new SaveCallback)
If it is because the update fails, then again implement the SaveCallback to see what Exception is thrown saveInBackground(new SaveCallback)
You should never be able to update any other User objects than your own. That would be a huge security issue. A work around could be to create a cloud function using useMasterKey() and call that function from your app.
