在一般来说，这些类型的工具是行不通的***选择。提出申请很容易崩溃，内存泄漏，你还有做大量的重复工作制作为iOS和Android的具体解决方案......不推荐。

In general these kinds of tools just doesn't work optimal. Applications made tend to crash, leak memory and you still have to do a lot of double work for making specific solutions for iOS and Android... not recommended.
