Cannot open database connection in android..

Hi...

I am developing an app for medical students which includes database. For database I have used sqilte. my app is running fine on editor and even after building for PC. But for android database connection is not establishing. I have checked for android my code is working fine till the path and it is getting correct path of database but cannot establish the connection.

here is my code

     conn = "URI=file:" + System.IO.Path.Combine(Application.streamingAssetsPath,"anatomy3D.s3db"); //Path to database.
     t.text =  conn;
     IDbConnection dbconn;
     dbconn = (IDbConnection)new SqliteConnection(conn);

     dbconn.Open(); //Open connection to the database.

     t.text = t.text + "\n database opened";
