Unfortunately all content of my database got deleted by me.

two ways is there
1) Access the phone internal storage to push in SQLite database file

I wrote an app that saves and uses data in/from a Cloud Firestore database. I would want to organize more clearly than for the moment my files, for example by using DOs and DAOs.
I know the concept of "DAO" exists in Android Room.
However, the documentation seems to define Android Room as a "local database". So if I understand it well, I shouldn't use it in addition to Firestore?
By the way, it would be the same with Firebase Cloud Realtime Database (a third database system).
Edit :
I didn't understand the notion of "local" database (Room). Tamir, in his answer, corrected me. This question is off-topic.
So if I understand it well, I shouldn't use it in addition to Firestore?
No and this is beacause Cloud Firestore has offline persistence enabled by default:
For Android and iOS, offline persistence is enabled by default. To disable persistence, set the PersistenceEnabled option to false.
This means that you'll have by default a local copy of your database. So there is no need to add another one.
Basically, when you are developing an app there would be some data that you will want to save into locally and other data that you will want to save on remote database, it's not a bad thing to have both remote and local database.
Some example that I can think of for saving your data remotely is to manage users - when a new user will be created you will want to check if the username is not taken, and you can't do it if this data is only stored locally.
And for using a local database - one of the major advantages in the local database vs remote database its the speed of writing and receiving data.
Here is a nice article on the subject.
i have created a database in sq-lite in-memory for my android app ,i want to push the in-memory database to file system. please help me out .
Tried looking for multiple places but could not find any solution.
I am trying to figure out how I would send a local SQLite database file that is created on runtime of my android app and send that database file to a cloud service so it can have that database in the cloud and I can fetch data from it.
I have already gotten my app to store SQLite database information on the device it self, but now I want to use Amazon Web Services for backing up my database onto those server.
Any tips,help, comments or suggestion are appreciated. Thank you!
How can I connect my local database in my application? I have a database which contains a book. I have to display it in my application in J2ME
Basically, in JME, an app can create a database which is a file stored in the RMS. Actually, there are several APIs that can help you in creating a Java ME database: Is there any option for local database like Sqlite for j2me - CLDC devices?
Anyway, I think the data in a sqlite database is not easily accessible to a JME app. It is not impossible but it, maybe, is complicated. Honestly, I don't know anyway to do it.
You have to create a server application where you access to database. Also your J2ME has to communicate with your server application for getting Data you want to display (Use HttpConnection Class).
In Mobile Application, you can not directly make connection with local or remote database. To Make Connection with Database , you need a middle tier called a web service. You can create web service in any platform like Java-Servlet, .net or in PHP. See this is a very simple example to work with MySql Database.
Hi we have an Android app that currently stores its data in xml files and are looking to move it to SQL Lite based database.
The app is a consumer of data and data is added through a windows application after the phone is connected to the PC (Currently both are done through xml files on the SD card)
If the data is stored on a SQLite database, is it possible to locate and connect to the database from a .NET application which can both enter and delete records from it.
Please advise. Thanks,
Yes. You will be able to connect and then manipulate a SQLite database from a .NET application. Use a data provider like System.Data.SQLite. The downloads are here.
