【问题描述】：
我在 Android Studio 中连接字符串时遇到了一个问题。似乎最大长度为 120 个字符，但仅限于连接时。
如果我有这个例子：
private static final String HOW_LONG_CAN_A_STRING_BE =
"123456789A"
+ "123456789A"
+ "123456789A"
+ "123456789A"
+ "123456789A"
+ "123456789A"
+ "123456789A"
+ "123456789A"
+ "123456789A"
+ "123456789A"
+ "123456789A"
+ "123456789A"
+ "";
String test = HOW_LONG_CAN_A_STRING_BE;
当我将鼠标悬停在字符串 HOW_LONG_CAN_A_STRING_BE 上时，它会解析连接的字符串。
但是，如果我像本例中那样添加更多字符：
private static final String HOW_LONG_CAN_A_STRING_BE =
"123456789A"
+ "123456789A"
+ "123456789A"
+ "123456789A"
+ "123456789A"
+ "123456789A"
+ "123456789A"
+ "123456789A"
+ "123456789A"
+ "123456789A"
+ "123456789A"
+ "123456789A"
+ "1";
String test = HOW_LONG_CAN_A_STRING_BE;
当我将鼠标悬停在 HOW_LONG_CAN_A_STRING_BE 上时，它会导致错误出现在 Android Studio 的事件日志中，其中包含以下详细信息：

这是一个问题，因为我正在尝试创建一个数据库，并且包含数据库创建语句的字符串大于 120 个字符。以前有没有人遇到过这个问题，如果有，我该如何解决它而不必让我的列名不可读？
这是失败的创建语句：
创建表提醒（ id 整数主键， createdAt TEXT, 开始日期文本， 结束日期文本， 提醒时间整数， 重复整数， 延迟时间整数， 报警整数， 提醒在 INTEGER 上， 说明文字 )【问题讨论】：
-
这只是悬停在变量上时的问题吗？
-
通过我的初始测试，当我运行代码时似乎并不重要。它必须只是一个 android studio 或 intellij-idea 问题。我将不得不密切关注它。
-
这个问题似乎已经通过更新到 Android Studio 版本 0.61 得到解决
-
一般来说，IDE 内部错误通常与你的代码本身没有任何关系。
