推荐答案

文档说:

从历史上看，这些方法比等效的基于double的方法要快 java.lang.Math方法.在具有JIT的Android版本上， 变得越来越慢，并且此后被重新实现以包装对 java.lang.Math.应该优先使用java.lang.Math.

Historically these methods were faster than the equivalent double-based java.lang.Math methods. On versions of Android with a JIT they became slower and have since been re-implemented to wrap calls to java.lang.Math. java.lang.Math should be used in preference.

所有方法均已从版本23的公共API中删除.

All methods were removed from the public API in version 23.

@deprecated改用java.lang.Math.

@deprecated Use java.lang.Math instead.

这意味着解决方案是使用Math类:

This means the solution is to use the Math class:

(float)Math.sqrt(...)
