SQLite unable to open database file (code 14) on frequent “SELECT” query

Question

I have following class \"Singleton\" to handle SQLite connection and to make sure to have 1 instance of connection for whole process/app:

public class DBCon         


        

Answer 1

In your Application class

public static SQLiteDatabase database;

@Override
public void onCreate() {
    super.onCreate();

    SQLiteOpenHelper helper = Database.getInstance(getApplicationContext());

    if (database == null) {
        database = helper.getWritableDatabase();
    } else {
        if (!database.isOpen()) {
            database = helper.getWritableDatabase();
        }
    }
}

In your queries class

 public DataSources() {
    database = ApplicationController.database;
 }

That way you create a writeable db object once
