Resolution : I was forgetting to put create in the right place.

public void onCreate(SQLiteDatabase database, ConnectionSource connectionSource) {
    try {
        TableUtils.createTable(connectionSource, ListenerList.class);
        TableUtils.createTable(connectionSource, ListenerItem.class);
        TableUtils.createTable(connectionSource, ListenerAlarme.class);
} catch (SQLException e) {
        Log.e(LOG_TAG, "Can't create database", e);
        throw new RuntimeException(e);
    }
}

 public void onUpgrade(SQLiteDatabase database, ConnectionSource connectionSource, int oldVersion, int newVersion) {
    if(oldVersion == 2) {
        try {
            TableUtils.createTable(connectionSource, ListenerAlarme.class);
        } catch (SQLException e) {
            Log.e(LOG_TAG, "Can't create database", e);
            throw new RuntimeException(e);
        }
    }
}
