提供向后兼容性时，如何摆脱弃用警告? [英] How to get rid of deprecation warnings when providing backwards compatibility?

问题描述

如何消除棉绒折旧警告?例如，烦人的NetworkInfo:

How one can get rid of linter deprecation warnings? For example, the annoying NetworkInfo:

warning: [deprecation] NetworkInfo in android.net has been deprecated

推荐答案

为了消除此类过时警告，在提供向后兼容性时，
必须删除不能应用的import @SuppressWarnings("deprecation"):

In order to get rid of such deprecation warnings, when providing backwards compatibility,
one has to remove the import, to which one cannot apply @SuppressWarnings("deprecation"):

// import android.net.NetworkInfo;

，然后使用完全限定的类名android.net.NetworkInfo而不是NetworkInfo.关键是，只能将@SuppressWarnings("deprecation")应用于方法，而不能应用于导入.

And then use it's fully qualified class name android.net.NetworkInfo instead of NetworkInfo. The point is, that one can only apply @SuppressWarnings("deprecation") to methods, but not imports.
