java.lang.IllegalStateException: attempt to re-open an already-closed object: SQLiteDatabase:

This error occurs when you try to access a closed SQLiteDatabase object. This can happen when you try to perform a database operation on a SQLiteDatabase object which has already been closed.

To resolve this error, you need to ensure that you are not trying to access a closed SQLiteDatabase object. You can do this by checking the state of the SQLiteDatabase object before performing any operation on it.

Here is an example of how you can avoid this error:

1. Open the SQLiteDatabase object:

SQLiteDatabase db = dbHelper.getWritableDatabase();

2. Check the state of the SQLiteDatabase object:

if (db.isOpen()) {
    // Perform database operations here
} else {
    // Handle the case where the SQLiteDatabase object is closed
}

3. Close the SQLiteDatabase object when you are done with it:

db.close();

By following these steps, you can avoid the IllegalStateException: attempt to re-open an already-closed object: SQLiteDatabase error.
