Question

我已经阅读了之前的帖子，但没有提供可行的解决方案（重启模拟器，逗号，间距调整）。

创建一个简单的SQLite数据库，但每次运行时都会收到相同的错误;

我的代码，我用不同的间距尝试了这个但无济于事;

// Login Table Columns names
    private static final String KEY_ID = "id";
    private static final String KEY_NAME = "name";
    private static final String KEY_EMAIL = "email";
    private static final String KEY_UID = "uid";
    private static final String KEY_CREATED_AT = "created_at";
    private static final String KEY_TEL_NO = "tel_no";

    public SQLiteHandler(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
    }

    // Creating Tables
    @Override
    public void onCreate(SQLiteDatabase db) {
        String CREATE_LOGIN_TABLE = "CREATE TABLE " + TABLE_LOGIN + "("
                + KEY_ID + " INTEGER PRIMARY KEY, "
                + KEY_NAME + " TEXT, "
                + KEY_EMAIL + " TEXT UNIQUE, "
                + KEY_UID + " TEXT, "
                + KEY_CREATED_AT + " TEXT, "
                + KEY_TEL_NO + " TEXT " + ")";
        db.execSQL(CREATE_LOGIN_TABLE);

        Log.d(TAG, "Database tables created");
    }

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

        // Create tables again
        onCreate(db);
    }

我错过了一些明显的东西吗？

是的，尽管重新启动了模拟器，但似乎我在另一个Android Studio窗口中运行的第二个应用程序，使用相同的数据库名称，每次运行主应用程序时都会启动。

感谢您回答，很抱歉浪费您的时间。
