I am creating an android app which stores data in the firebase database and I have made an Admin Panel which stores data in the localhost database. So I want to retrieve data of firebase and show in the localhost database. What should I do?
Thanks in advance. :)

now I'm working on hybrid mobile application with SQLite. This application just only retrieve the data from database. The data come from MYSQL database, but I want to store the large amount of data into local storage which is SQLite so when the user don't have the internet, they can retrieve the data from local storage. So,is there a way to connect mysql db and sqlite? I have been following the tutorial from this site
but I do not know how to connect sqlite with mysql db. So,anyone can help me to solve my problem ?
In my app, I have an SQLite/Room database. I want to introduce synchronisation between the devices of my users.
I want to combine my local SQLite/Room DB with a cloud Firebase DB.
I want my SQLite database to be stored in the Firebase Database when the users are logged in, otherwise let it store offline. Any changes to the local database should be reflected in Firebase Database when logged in. Also if a user deletes the local database he/she can retrieve it from Firebase Database. I just want to use Firebase for the synchronization between the local database and Firebase Database.
How can I do it? My app is in Android with Java as a backend.

I don't see any reason why you would add an additional local database to your application, since both Firestore and the Realtime Database have their own offline persistence mechanism. However, you can implement such a feature but you should take into consideration that the entire mechanism of synchronization should be managed by you.

This can be simply done without a local database. How can you achieve that? Simply by attaching an auth state listener to track the user auth state. This means that when you're using Firestore, you can specify the source for reading the data. For example, if the user is authenticated you can read the data from Source.SERVER, otherwise from Source.CACHE.
Also if the user deletes the local database he/she can retrieve it from Firebase Database.
There's currently no API that does that. You should implement your own mechanism. You should track the user when it deletes the database and then take some actions accordingly.
I have one mobile app, and every customer have a lot of data under user account. It is possible to make one database firebase for each customer ? Xamarin app...
You can create multiple databases directly from the Firebase Console as mentioned here.
In case you need to create the databases programmatically as new users sign up or so, then you need to use Firebase Realtime Database Management API.
To create a new database, make a POST request:
https://firebasedatabase.googleapis.com/v1beta/{parent=projects/*/locations/*}/instances
I was able to configure the Firestore database in Firebase with my flutter app and also create and read documents from my collection but when I go to Firestore console I don't see the created data, also when I creat data manually I am unable to see it in my application.
I am using the test mode which means any user can read or write.
I hope someone can help me with this puzzle.
Thanks!!!
It sounds like the device/emulator that you are running on is not connected to the internet, or at least not to the Firestore servers. In that case, the client writes all local changes into a local database, waiting to send them to the server when it gets a connection. So the local app will work, but won't be able to synchronize its local cache with the database servers.
You might want to check the connection on your device, and any proxies that might exist between your app and the Firestore servers.
My app send somme data to firebase storage but it is possible that the connection is off when the app want to send those data. I hear that i can achieve that by enabling local storage, i want to known how?
