错误:迁移到androidx后找不到符号类MediaStyle [英] error: cannot find symbol class MediaStyle after migrating to androidx

问题描述

android.support.v4.media.app.NotificationCompat.MediaStyle()在音乐播放器应用程序中工作正常，但迁移到android x后出现此错误:找不到符号类MediaStyle.任何帮助将不胜感激.

android.support.v4.media.app.NotificationCompat.MediaStyle() was working fine in a music player application but after migrating to android x I get this error: cannot find symbol class MediaStyle. Any help would be appreciated thanks.

推荐答案

在AndroidX中，该特定样式位于其他程序包中.您需要在媒体样式之前添加"androidx.media.app".

In AndroidX, that specific style is located in a different package. You need to prepend the media style with 'androidx.media.app'.

换句话说:

builder.setStyle(new androidx.media.app.NotificationCompat.MediaStyle());

很奇怪，我不需要在gradle文件中实现此程序包，因此它可能与AndroidX内部依赖项有关.

Curiously enough, I didn't need to implement this package in my gradle file, so it could be something related to AndroidX internal dependencies.
