[Unity] Problem with SQLite on Android
Hello, I have been trying to get SQLite to work on my Android device for days now. First of all, I want to point out, that everything works fine on the computer. I can read and write to the created SQLite database with no errors.
The problem starts when I export the project to .apk and install it on my Android device. When I'm trying to do anything involving the databse, nothing is happening.
The logcat message: 
What have I done to this point:
Downloaded and put sqlite3.dll to Assets/Plugins folder
Copied System.Data.dll and Mono.Data.Sqlite.dll from Unity\Editor\Data\Mono\lib\mono\2.0 folder to Assets/Plugins folder in my project
Created database using 'SQLite Administrator tool' and put it in the Assets folder
Created Assets/Plugins/Android folder and put libsqlite3.so in it
As I said before, this works perfectly fine on the computer (in the Unity Editor), but not on the Android device.
I was looking for the solution everywhere, but in most cases putting libsqlite3.so to the Assets/Plugins/Android solved the problem. Any help will be appreciated.
I've got exactly the same problem and can't find working solution anywhere ;/
So... how did you do it @grzekos ? Did you found the solution? Have similar problem...
Hello, you solved the problem, it happens to me too. This is the code I use.
try
{
string conn = "URI=file:" + Application.dataPath + "/Base de Datos/Catalogo.s3db"; //Path to database.
Debug.Log(conn);
IDbConnection dbconn;
dbconn = (IDbConnection)new SqliteConnection(conn);
dbconn.Open(); //Open connection to the database.
IDbCommand dbcmd = dbconn.CreateCommand();
string CodigoCategoria = VariablesGlobales.codigoCategoria != null ? VariablesGlobales.codigoCategoria : "ninguna";
string sqlQuery = "select codigoCategoria,NombreCategoria from Categorias where codigoCategoria='" + CodigoCategoria + "' ";
dbcmd.CommandText = sqlQuery;
IDataReader reader = dbcmd.ExecuteReader();
if (reader.Read())
{
string codigoCategoria = reader.GetString(0);
string NombreCategoria = reader.GetString(1);
TituloCategoria.text = NombreCategoria;
}
reader.Close();
reader = null;
dbcmd.Dispose();
dbcmd = null;
dbconn.Close();
dbconn = null;
}
catch (Exception exe)
{
Debug.Log(exe.$$anonymous$$essage);
}
Try putting the database in StreamingAssets folder or use file I/O and save it to Application.PersistantDataPath
Seems like it's also not able to find the actual sqlite dll though. Could be that the dll is not supported on Android.

I've used this library with success for compiling on Android
