现在，我们知道如何利用Scala代码，将它转换成将在Android设备上运行的二进制格式，接下来可以使用Scala创建一个移动应用程序。

Now that we know how to take Scala code and turn it into the binary format that will run on an Android device, it's time to create a mobile application using Scala.

目标语言通常为二进制格式（如机器代码），但不总是这种格式。

Often the target language is a binary format like machine code, but not always.

当我提到字符格式 要比二进制码格式慢时，你说，从效率的角度来看，二进制代码格式使得软件更加难以维护。

When I mentioned that a character format could be slower than a binary format, you said the binary approach makes things harder to maintain in the name of efficiency.
