problems in creating multiple tables in sqlite

Question

I'm using the following code for creating multiple tables in a database. But, I don't understand why this problem happens.

private static final String TABLE_SMSFilter = "SMSFilter";


public void onCreate(SQLiteDatabase db)
    {
        Log.d("Test", "Control is in Oncreate()");
        String CREATE_SMSSSCHEDULE_TABLE = "CREATE TABLE " + TABLE_SMSSchedule
                + "(" + KEY_ID + " INTEGER PRIMARY KEY autoincrement,"
                + KEY_NUMBER + " TEXT)";

        String CREATE_PROFILE_SCHEDULE_TABLE = "CREATE TABLE "
                + TABLE_ProfileSchedule + "(" + ProfileSchedule_ID
                + " INTEGER PRIMARY KEY autoincrement,"
                + ProfileSchedule_NUMBER + " TEXT, "
                + ProfileSchedule_ProfileMode + " TEXT,"
                + ProfileSchedule_CalendarID + "INTEGER)";

        String CREATE_SMS_FILTER_TABLE = "CREATE TABLE " + TABLE_SMSFilter
                + "(" + SMSFilter_ID + " INTEGER PRIMARY KEY autoincrement,"
                + SMSFilter_NUMBER + " TEXT)";

        db.execSQL(CREATE_SMSSSCHEDULE_TABLE);
        db.execSQL(CREATE_PROFILE_SCHEDULE_TABLE);
        db.execSQL(CREATE_SMS_FILTER_TABLE);
    }

    // Upgrading database
    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion)
    {
        // Drop older table if existed
        db.execSQL("DROP TABLE IF EXISTS " + TABLE_SMSSchedule);
        db.execSQL("DROP TABLE IF EXISTS " + TABLE_ProfileSchedule);

        db.execSQL("DROP TABLE IF EXISTS " + TABLE_SMSFilter);

        // Create tables again
        onCreate(db);
    }

here is the insert function

public void addSMSFilter(SMSFilter filterVariable)
    {

        SQLiteDatabase db = this.getWritableDatabase();

        ContentValues values = new ContentValues();
        values.put(SMSFilter_NUMBER, filterVariable.getPhoneNumber()); // Contact
                                                                        // Name
        // values.put(KEY_PH_NO, contact.getPhoneNumber()); // Contact Phone

        Log.d("test", "inserting" + filterVariable.getPhoneNumber());
        // Inserting Row
        db.insert(TABLE_SMSFilter, null, values);

        db.close(); // Closing database connection
    }

and now in my main activity, I used this code to insert into this table

DatabaseHandler db = new DatabaseHandler(this);

        SMSFilter sms = new SMSFilter("1234556");
        db.addSMSFilter(sms);

but it gives me the error that no table "SMSFILTER" found.

Log result is here

Answer 1

onUpgrade is called when databse version number is changed. When updating your table you need to increment database version number, specify new table creation query in onCreate method and put ALTER TABLE to onUpgrade method to update previous version of table. When Android detects database version mismatch, it will call onUpgrade method automatically
