Didn't find class " androidx .core.content.FileProvider" on path... Didn't find class " android . support . v4 .content.FileProvider" on path... 把这两个库放到 Assets\Plugins\ Android \ 目录下即可。 另外， Android Manifest.xml 文件中， <provider android :name=" android . support . v4 .content.FileProvider" <provider android :name=" androidx .core.content.FileProvider" 做音乐播放器，必然要用到通知栏，由于通知栏很多版本都有改动，一些厂商也做了调整，适配起来比较麻烦，能用系统自带的就用。这里分享一下系统媒体通知栏的适配。需要考虑的问题如下：1，通知栏适配，音乐播放需要常驻，所以要维护一个通知栏。2，音控处理，在安卓7.0及以下，通过MediaSessionCompat可控制锁屏页音乐播放。3，对于耳机的处理，不管是线耳机还是蓝牙耳机，耳机控制播放暂停，下一曲上一曲等操作。4，打电话处理，在听音乐的同时如果电话进来后挂断，希望可以自动播放。 在 Android Manifest.xml中加入下面这段话后， <provider android :name= android . support . v4 .content.FileProvider android :authorities=com.boxin.forklift.fileprovider android :exported=false android :grantUriPermissions=true> <meta-data android :name= android . support .FILE_PROV 一劳永逸方法 网上的其他方法比如修改compileSdkVersion，buildToolsVersion，和 app compat的版本号，虽然可以解决问题，但是下一次新建 项目 的时候还会出现，又得继续改版本号。下面的解决方法可以一次性解决 在你的 Android Studio中找到这个目录。 android -studio-ide-2.3.3\ android -studio\plugins\ android \lib\templates\gradle-projects\New Android Project\root\ 找到build.gradle.ftl文件 编辑 ，在 allprojects ok，问题得到解决了，主要的原因出现以下几点，1、你的Mian Activity 应该要继承 Fragment Activity 类 2、引入 android . support . v4 . app . Fragment Activity ;修改过的代码改为如下：package com.example.test fragment ;import android . app . Activity ;import android . app .Acti... 更新了 Android Studio3.4的小伙伴可能会遇到无法导入 V4 包的问题，即使显示已经导入 插入import android . support . v4 . app . Fragment ; Fragment 显示红色 那是因为较新版的安卓默认使用 androidx 的包，摒弃了以前的 support 包 如果开启了自动导包，使用ViewPager + fragment 的时候会自动导入 androidx 的包 impo...
