How to work with sqlite DataBase in Xamarin Android?

I searched for along time for how can I use a pre made Excel table, as a reading database in Xamarin.Android.
Of course I can't use it directly, so I tried many different ways. For example, convert to Json, upload to Firebase, and later download it, while the program runs, and fill the sqlite. This way is not effective aadn most of the time doesn't work.
Is there any chance, that someone could please explain or even give a tutorial on how to create sqlite database and work with it directly? If there any other worse or better ways to do it, please tell me.
Thank You!

If you want use sqlite DataBase for Xamarin.Android, you could use sqlite-net-pcl.
Install from NuGet: sqlite-net-pcl
You could cgeck the MS docs from the link below for reference. https://learn.microsoft.com/en-us/xamarin/android/data-cloud/data-access/using-sqlite-orm

I think I understand your question:
You can write and read data per tag.
Make sure your ProjectBucket is correct.

SQLITE DATABASE for multiple access

I would like to ask if any of you out there uses android studio and sqlite for apps that require multiple users to access the database? I have been looking for source codes and examples online, but haven't seen any. I understand that other database might be better but I only have enough time to use sqlite as I am alr using it now. Could anyone help me with example source codes?

viewComment.setText(name+comment);
replace with below code
viewComment.append("\n"+name+comment);
Update -
limit number comments - use counter , after certain number of hits stop appending to text view.
U can make scrollable too.
for above both please check your requirements or UI/UX teams.

You will have to work with RecyclerView here. Add a different layout resource file in your layout folder and bind it to the RecyclerView and all your comments must be stored somewhere, like in a database. You will then achieve your desired structure.

Making a database with android?

I'm working on an android project that requires writing to a created database and later reading from it.
The idea is for the user to fill out a form and then submit, it will submit into a database table in the first row. Then if they hit submit again it will submit to the second row.
I have all of the activity layouts defined but I'm confused on how to make the databases. I'm thinking maybe I can make a content provider?
Can anyone advise me on what to do? All of the questions I look at on here skip the baby steps, and that's what I need

Yes you should make a content provider. There are a lot of great tutorials out there for making databases - try section 8.0 of this one
http://www.vogella.com/articles/AndroidSQLite/article.html

Since you plan to use a pre-loaded (created) database wherein the DB structure has been already defined, Refer to this link on how to include your pre-created DB file into your app :
http://www.reigndesign.com/blog/using-your-own-sqlite-database-in-android-applications/
And to then add new data to your database refer to this tut.. You can ignore the create Table part here since you already have the table structure ready.

Hope this helps.

First of all you dont need Content provider...Content provider is only need when you want to provide your data to other application...Its kind of central repository of data for other applications.
Now You have to use the SQLITE database in android...Since android support sqlite database..
Below link will guide you...
http://developer.android.com/training/basics/data-storage/databases.html

Google has large manuals for all the aspects of Android development http://developer.android.com/training/basics/data-storage/databases.html

it might be done without content providers too.
this might be helpful.

If any good sample code example is there please give the link.
Thanks in advance.

Here you can find a simple and straight forward tutorial from anddev.
Summarize from the tutorial:
Description: We'll need to to the
following things:
Create a DataBase (generally this is done just once)
Open the DataBase
Create a Table (generally this is done just once)
Insert some Datasets
Query for some Datasets
Close the Database

Android uses the SQLITE database Read up on it here: http://www.screaming-penguin.com/node/7742

I assume you have read the official Android developer guide. If not, there is a wealth of information about doing anything and everything you'd want on an Android device.
Since Android uses SQLite as it's internal database, I'd suggest reading documentation about it + the data storage part of Android guide.
These would be good starting points.
