在iOS内，BOOL 是0|1，在Android里是true|false，我在iOS里保存了一个BOOL，在android上取出来，碰到了这样一个问题java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.Boolean，如何解决？

具体log：

现在的解决方案是：在Android中获取boolean值时，做个判断，code snippet:

    public boolean getBooleanKey() {
        Object obj = get("booleanKey");
        if (obj instanceof Integer)
            return getInt("booleanKey") == 1;
        return getBoolean("booleanKey");
    }
