使用方法

module的build.gradle中的添加依赖，自行修改为最新版本，同步后通常就可以用了：

dependencies {	...	implementation 'cn.wandersnail:file-selector:latestVersion'	implementation 'com.github.bumptech.glide:glide:latestVersion'	implementation 'cn.wandersnail:common-base:latestVersion'	implementation 'cn.wandersnail:common-utils:latestVersion'}

如果从jcenter下载失败。在project的build.gradle里的repositories添加内容，最好两个都加上，添加完再次同步即可。

allprojects {	repositories {		...		mavenCentral()		maven { url 'https://dl.bintray.com/wandersnail/androidx/' }	}}
