SQLite c#

Hi! I'm trying to port my wear os app to tizen (due to switching from ticwatch pro to galaxy watch), but i have some problems. I have a db in my shared/res directory in visual studio project, and i'm trying to open it with sqlite (throught methods of System.Data.SQLite), without success, because i obtain a segmentation error when i create sqlite connection to db...is shared/res maybe read only directory, as in android? If yes, how can i solve the problem?

Here is the code:.

MainApps:

protected override void OnStart()
        {
            // Handle when your app starts
            String db_path = "/opt/usr/apps/com.feduss.example.BusFinder.Tizen.Wearable/shared/res/CTM_BUS.sqlite";

            SQLiteDatabase db = new SQLiteDatabase(db_path);
            if (File.Exists(db_path))
            {
                Console.WriteLine("File exists...");
                SQLiteCommand selectBusLines = new SQLiteCommand
                ("SELECT * from Routes");
                DataTable res = db.GetDataTable(selectBusLines);
            }
            else
            {
                Console.WriteLine("File does not exist!");
            }
        }

SQLiteDatabase.cs:

public class SQLiteDatabase
    {
        private readonly string _dbConnection;

        public SQLiteDatabase(string dataSource)
        {
            _dbConnection = string.Format("Data Source={0}", dataSource);
        }

        public DataTable GetDataTable(SQLiteCommand command)
        {
            if (command == null) throw new ArgumentNullException("command");

            using (SQLiteConnection connection = new SQLiteConnection(_dbConnection))
            {
                connection.Open();
                command.Connection = connection;

                using (SQLiteDataReader reader = command.ExecuteReader())
                {
                    DataTable result = new DataTable();
                    result.Load(reader);
                    return result;
                }
            }
        }

        public SQLiteCommand GetCommand(string sql)
        {
            if (string.IsNullOrEmpty(sql))
                throw new ArgumentNullException("sql");

            return new SQLiteCommand
            {
                CommandText = sql,
                CommandType = CommandType.Text
            };
        }

        public int ExecuteNonQuery(SQLiteCommand command)
        {
            if (command == null) throw new ArgumentNullException("command");

            using (SQLiteConnection connection = new SQLiteConnection(_dbConnection))
            {
                connection.Open();
                command.Connection = connection;

                return command.ExecuteNonQuery();
            }
        }
    }

Hello, it is great to hear that you are trying to port your app to Tizen.

1. Putting your db file in `shared/res` seems quite all right. However, you can get the exact path by using an API `Tizen.Applications.Application.Current.DirectoryInfo.SharedResource` which you can use after installing `Tizen.NET` nuget package.

2. Using `sqlite-net-base`package is recommanded for Tizen. (Install `sqlite-net-base` to a shared project and install `SQLitePCLRaw.provider.sqlite3.netstandard11` to the Tizen project.)

    - `System.Data.SQLite` is not fully tested, so you may need to do more work to make it running on the Tizen devices.

3. Here is the sample application using sql: https://github.com/Samsung/Tizen-CSharp-Samples/tree/master/Wearable/VoiceMemo

4. You could check dlog with the tag "DOTNET_LAUNCHER" to see the exeption. ( ex: "shell ~ $ dlogutil DOTNET_LAUNCHER ")

Hi! Thanks for your reply! Unfortunally, sample code is not working, i always get segmentation fault during the creation of the new SQLiteAsyncConnection(path);

 

string resPath = Tizen.Applications.Application.Current.DirectoryInfo.SharedResource;
string db_name = "CTM_BUS.db";
string dbfile = "/home/owner/apps_rw/com.feduss.example.BusFinder.Tizen.Wearable/shared/res/CTM_BUS.db";
SQLiteAsyncConnection database;
database = new SQLiteAsyncConnection(resPath); //Segmentation fault

 

Moreover, dotnet_launcher log doesn't tell me anything of understandable :(...

 

Here is the log:

'shared/res' is a read-only directory for resource files. The detailed information about the directory can be found here. You can instead use the app's data directory (Tizen.Applications.Application.Current.DirectoryInfo.Data) or the device internal storage (Tizen.System.DirectoryType.Documents) to store the database file.

 

Also could you let me know where you could see the segmentation fault (any specific error logs?)

 

Jay Cho

Thanks @Sangwook Kim for the correction.

@feduss, please try again as Sangwook said. Maybe you want to use `Application.Current.DirectoryInfo.Data` combining your db file name.

Hi!

If i copy the db from Tizen.Applications.Application.Current.DirectoryInfo.SharedResource + db_name to Tizen.Applications.Application.Current.DirectoryInfo.Data throught File.Copy, the app gives me segmentation error in SQLiteConnection

String db_name = "CTM_BUS.db"; //db name

//Copy db from shared/res to shared/data
File.Copy(
    Tizen.Applications.Application.Current.DirectoryInfo.SharedResource + db_name,
    Tizen.Applications.Application.Current.DirectoryInfo.Data + db_name);

//Segmentation error here, without details
SQLiteAsyncConnection database = new SQLiteAsyncConnection(Tizen.Applications.Application.Current.DirectoryInfo.Data + db_name);

Tizen.Applications.Application.Current.DirectoryInfo.SharedResource is not the correct path to the app shared/res.

Btw, i tried to copy the db from app's shared/res + db_name to  Tizen.Applications.Application.Current.DirectoryInfo.Data throught File.Copy, but it gives me Segmentation fault (maybe data dir doesn't exist, even if if put the http://tizen.org/privilege/appdir.shareddata permession)

String db_name = "CTM_BUS.db"; //db name

//Tizen.Applications.Application.Current.DirectoryInfo.SharedResource is not the correct path to shared/res of app!

//Copy db from shared/res to shared/data
//It gives me segmentation error
File.Copy(
    "/home/owner/app_rw/com.feduss.example.BusFinder.Tizen.Wearable/shared/res/" + db_name,
    Tizen.Applications.Application.Current.DirectoryInfo.Data + db_name);

//Connection to db
SQLiteAsyncConnection database = new SQLiteAsyncConnection(Tizen.Applications.Application.Current.DirectoryInfo.Data + db_name);

My db is under:

/home/owner/app_rw/com.feduss.example.BusFinder.Tizen.Wearable/shared/res/

Hi, let me share the simple code you can check.

I installed `sqlite-net-base` and `SQLitePCLRaw.provider.sqlite3.netstandard11` like I explained at the very first comment.

Add using statements

```c#

using SQLite;
using SQLitePCL;

```

and I could find the db file created on the proper path with the following code.

```c#

try
{
    string db_path = Path.Combine(Tizen.Applications.Application.Current.DirectoryInfo.Data, db_name);
    Console.WriteLine("Path " + db_path);

    // To me, it prints "Path: /opt/usr/home/owner/apps_rw/org.tizen.example.CrossTemplate4.Tizen.Wearable/data/CTM_BUS.db"

I just found your comment before I left..so I am just quicky sharing this before I left.

Let me know if this way doesn't fit on your application. Thanks.

Sorry, i mean "/opt/usr/home/owner/app_rw/com.feduss.example.BusFinder.Tizen.Wearable/shared/res/" (in device manager, while in visual studio in BusFinder.Tizen.Wearable/shared/res/)

feduss

Sorry, nope, this file system is confusing me...the correct path of db if this from VisualStudio

 

BusFinder.Tizen.Wearable>shared/res/CTM_BUS.db

feduss

ok, new update:

I found the correct APIs to get paths, but i always get SegmentationFault in SQLiteAsyncConnection.

This is the code:

public App()
        {
            InitializeComponent();

            MainPage = new Ctm_finder.MainPage();

            String db_name = "CTM_BUS.db"; //db name
            Boolean exist = false;

            String res_path = Tizen.Applications.Application.Current.DirectoryInfo.SharedResource;
            String res_filename = Path.Combine(res_path, db_name);

            //Check if db exists
            if (File.Exists(res_filename))
            {
                String data_path = Tizen.Applications.Application.Current.DirectoryInfo.Data;
                String data_filename = Path.Combine(data_path, db_name);

                File.Copy(res_filename, data_filename);

                //Check if new file exists
                if (File.Exists(data_filename))
                {
                    //Segmentation fault
                    SQLiteAsyncConnection database = new SQLiteAsyncConnection(data_filename);
                    exist = true;
                }
                //File not copied correctly
                else exist = false;

                
            }
            //Db doesn't exist in shared/res
            else exist = false;
            
        }

That's my config:

It's great to hear that it works with the sample code.

Is it know if files stored in:

Tizen.Applications.Application.Current.DirectoryInfo.Data

will survive between application updates?

feduss

I don't know, my app isn't yet on samsung store because of isn't finished yet :/

Hi everyone! I've done like here and have following error with Tizen 5:

Method not found: 'Int32 SQLitePCL.ISQLite3Provider.sqlite3_win32_set_directory(Int32, System.String)'.

With T4 have segmentation fault as usual with null exception (Exception e, e == null)

I've included sqlite-net-base v1.7.335 and SQLitePCLRaw.provider.sqlite3.netstandard11 v1.1.14

Project setup for tizen 4.0

 

dataPath is "/opt/usr/home/owner/apps_rw/org.tizen.example.sqlite.NET/data/sqlitenet.db3"

Crashing somewhere here:

        private void InitiateSQLite(string databasePath)
        {
            // Need to initialize SQLite
            raw.SetProvider(new SQLite3Provider_sqlite3());
            raw.FreezeProvider(true);
            Database = new SQLiteConnection(dataPath);

Any tips? Thank you!
