SQLite - Could not open database file

Question

I am coding a Xamarin Android application, and am getting an error when trying to create a SQLite database.

Here is my code:

string applicationFolderPath = System.IO.Path.Combine(System.Environment.GetFolderPath(System.Environment.SpecialFolder.Personal), "CanFindLocation");
string databaseFileName = System.IO.Path.Combine(applicationFolderPath, "CanFindLocation.db");
SQLite.SQLite3.Config(SQLite.SQLite3.ConfigOption.Serialized);
var db = new SQLiteConnection (databaseFileName);

Here is the error that I am getting:

SQLite.SQLiteException: Could not open database file: /data/data/com.xamarin.docs.android.mapsandlocationdemo2/files/CanFindLocation/CanFindLocation.db (CannotOpen)

I have the same code working in another Xamarin application and would like to know if the exception has something to do with the name of the package?

Thanks in advance

Does the path folder path that you are providing to SQLite exist? If you haven't created the CanFindLocation folder then opening a connection to that path will fail.

Try:

string applicationFolderPath = System.IO.Path.Combine(System.Environment.GetFolderPath(System.Environment.SpecialFolder.Personal), "CanFindLocation");

// Create the folder path.
System.IO.Directory.CreateDirectory(applicationFolderPath);

string databaseFileName = System.IO.Path.Combine(applicationFolderPath, "CanFindLocation.db");
SQLite.SQLite3.Config(SQLite.SQLite3.ConfigOption.Serialized);
var db = new SQLiteConnection (databaseFileName);
