I am using Firestore as a NoSQL databse in my Android app. I want to store data locally in my Android device and avoid syncing with Firestore server in the initial stages of app. Is is possible for the data to persist on device even if app or mobile device restarts without syncing with Firestore database? If yes then how do I do it ?
I want to store data locally in my android device and avoid syncing with Firestore server in the initial stages of app.
According to the official documentation regarding Firestore offline persistens:
For Android and iOS, offline persistence is enabled by default. To disable persistence, set the PersistenceEnabled option to false.
And to answer the second question:
Is is possible for the data to persist on device even if app or mobile device restarts without syncing with Firestore database?
Yes it is. This kind of persistens is called disk persistence, which means that recently listened data (as well as any pending writes from the app to the database) are persisted to disk. The data in this cache survives app restarts, and phone reboots.
I am building an Android application for order placement for a car showroom. My customer already has an installed Oracle database where their data is stored. My customer asked me to synchronize this Android application with his old database.
I made an Android application that can connect to database using JSBC.
When I run this Android application on an Android emulator it property retrieves data from oracle database. But when I build its .apk file and install it on mobile, its not getting data from database.
Note: remember my database is installed of server and my laptop is connected through LAN.
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!
I use the Parse.com Cloud service in my Android app to sync data between devices.
I use the app mainly offline and use the local DB
Parse.enableLocalDatastore(getApplicationContext());
I would like to use PinInBackground() to store the data locally and sync once every day by hitting the sync button in my app.
Now if my app crashes or the device restarts - how do I know which objects are stored only locally so I can sync them with Save()?
pinInBackground() will not save to the cloud eventually. The only action that does BOTH is saveEventually(), which will pin your objects locally if your network is down so that you can still query them even though you are still offline.

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.
